Chapter 24 ERRP Command Configuration
24.1 Brief introduction of ERRP
ERRP(Ethernet Ring Redundancy Protocol) is the private Ethernet ring protocol of QTECH which is used to
protect real-time service (video/voice delay sessitive service). The basic working theory is many switches serial
connect to be ring to provide link redundancy, and a master device detects/maintains the ring. The master device
provides redundant port which can release redundant port when the ring break down to guarantee the service smooth.
The calculation is less, so the convergency is faster than STP.
24.2 ERRP Overview
Ethernet Ring Redundancy Protocol (ERRP) is an Ethernet ring-specific link layer protocol. It can not only
prevent data loop from causing broadcast storm efficiently when the Ethernet ring is complete, but also restore
communication channels among nodes on the Ethernet ring rapidly when a link is torn down.
Compared with Spanning Tree Protocol (STP), ERRP features :
Expedited topology convergence
Independent of the number of nodes on the Ethernet ring
24.3 Basic Concepts in ERRP

24.3.1 ERRP domain
The interconnected devices with the same domain ID and control VLANs constitute an ERRP domain. An
ERRP domain contains multiple ERRP rings, in which one ring serves as the primary ring and other rings serve as
subrings. You can set a ring as either the primary ring or a subring.
As shown in Figure 1, Domain 1 is an ERRP domain, including two ERRP rings : Ring 1 and Ring 2. All
the nodes on the two ERRP rings belong to the ERRP domain.

- If the master priority in the vrrp advertisement is higher than the priority of the router the router remains as a backup 93
- If the master priority in the vrrp advertisement is lower than the priority of the router when the router works in preemptive mode it becomes the master to periodically send vrrp packets when the router works in non preemptive mode it remains as a backup 93
- If the priority of a backup is higher than that of the master whether a new master needs to be elected depends on the working mode of the backup preemptive or non preemptive 93

- Bfd control packet authentication fields 111
- Bfd control packet format 111
- Bfd control packets 111
- Bfd packets 111
- Field description 111
- Figure 3 shows the format of the required fields 111
- Figure 4 shows the format of the optional authentication fields 111
- Qtech software configuration manual 111
- Table 1 description of the fields of a bfd control packet 111
- A session to be established the following example shows the session establishment process with both ends working in the active mode the session establishment process with one end in active mode and the other in passive mode is the same 112
- Active mode before a session is established bfd actively sends bfd control packets regardless of whether any bfd control packet is received from the peer 112
- Before a bfd session is established there are two bfd operation modes active or passive 112
- Bfd control packets are encapsulated in udp packets using destination port 3784 and a source port from 49152 to 65535 112
- Bfd echo packets 112
- Bfd echo packets are encapsulated in udp packets using destination port 3785 with the ip address of the transmitting interface as the destination ip address and a configured source ip address which must not cause icmp redirection 112
- Bfd echo packets provide a fault detection mechanism without the use of bfd control packets one end sends bfd echo packets to the peer which returns received bfd echo packets back without processing them therefore no bfd echo packet format is defined as long as the transmitting end can distinguish between sessions through packet contents 112
- Bfd session establishment 112
- During session initialization at least one end of the two in communication must operate in the active mode for 112
- Field description 112
- Passive mode before a session is established no bfd control packet is sent until a bfd control packet is received from the peer 112
- Qtech software configuration manual 112
- Application routers a and b send a bfd control packet in down state to the peer 113
- As shown in the above figure upon receipt of a notification from an upper layer 113
- Both bfd peers are up a session is established successfully and bfd starts to 113
- Detect link failures 113
- Local session state transits from init to up in the bfd control packet sent subsequently the sta field is filled with a value of 3 indicating the session state is up router b experiences the same bfd state transition as router a 113
- Session state transits from down to init in the bfd control packet sent subsequently the sta field is filled with a value of 2 indicating the session state is init router a experiences the same bfd state transition as router b 113
- Timer negotiation 113
- When router a receives the bfd control packet in init state from the peer the 113
- When router b receives the bfd control packet in down state the local 113
- After bfd session establishment and timer negotiation both ends start to transmit bfd control 115
- Application scenarios 115
- Configuring bfd for routing protocols 115
- Fault detection 115
- Packets at the negotiated interval each time a bfd control packet is received the detection timer is reset so that the session remains up if no bfd control packet is received within the detection timer the bfd session state transits to down and bfd notifies the failure to the upper layer application it services the upper layer application then takes proper measures when the bfd session on the local end is down the sta field of the bfd control packet transmitted to the peer is filled with a value of 1 to notify the peer that the session is down then the bfd session state of the peer also transits to down 115

- A bgp router filters routes in the following order 157
- Bgp route advertising policy 157
- Bgp routing policy 157
- Bgp routing tables in a large scale network may be huge in size route summarization can largely diminish 157
- Cannot be advertised outside the confederation they can only be advertised in the sub ass in the confederation 157
- Chooses routes in the order of the route origin type that is the order of igp egp and incomplete 157
- Chooses the route learnt from ebgp the route learnt from confederation and the route learnt from the ibgp in turn 157
- Does not send ibgp routes to its ibgp peers 157
- Drops the next_hop unreachable route 157
- No_advertise routes with this attribute cannot be advertised to any other bgp peers after being received by a bgp router 157
- No_export_subconfed routes with this attribute can neither be advertised outside the local as nor be advertised to other sub ass inside the confederation after being received 157
- Prefers the route with highest local_pref value 157
- Prefers the route with the lowest med value 157
- Prefers the route with the shortest as path 157
- Prefers the route with the smallest originator id 157

- The disadvantage of confederation is that when an as changes from non confederation to confederation configurations are needed on the routers and the topology changes 161
- To a bgp speaker that does not belong to any confederation the sub ass of a confederation are a whole and the information about the sub ass is invisible to the bgp speaker the confederation id which is usually the corresponding as number uniquely identifies a confederation in figure 13 as 200 is a confederation id 161

- Multicast implementation 168
- Overview 168
- Multicast addressing mechanism 169
- As for link layer multicast this document focuses on the multicast implementations of the ethernet protocol only and the multicast implementations of other link layer protocols are out of the scope of this document 170
- Figure 3 ip to mac address mapping 170
- Group membership management 170
- Igmpv1 documented in rfc 1112 defines the group member query and report processes 170
- Igmpv2 documented in rfc 2236 adds a leave group mechanism based on igmpv1 170
- Multicast address mapping 170
- A major enhancement in igmpv3 documented in rfc 3376 is that it allows hosts to specify a list of sources they expect or do not expect multicast data from the source specific multicast ssm model needs the support of igmpv3 171
- Figure 4 how igmpv2 works 171
- Igmp snooping 171
- Based on the group memberships maintained by igmp an intra domain multicast routing protocol builds multicast distribution trees according to certain 172
- Multicast forwarding tree 172
- Multicast packet forwarding 172
- Multicast packet forwarding mechanism 172
- Multicast routing protocols 172
- Able to differentiate the unicast topology and the multicast topology 174
- Having a set of stable methods for peering and policy control 174
- Inter domain multicast routing protocols 174
- Multicast border gateway protocol mbgp is used for exchanging multicast routing information between ass 174
- Multicast source discovery protocol msdp is used for advertising multicast source information between internet service providers isps 174
- When a multicast source sends multicast data to a multicast group the source side dr first registers the multicast source with the rp by sending register messages to the rp by unicast the arrival of a register message at the rp triggers the establishment of an spt then the multicast source sends subsequent multicast packets along the spt to the rp upon reaching the rp the multicast packet is duplicated and delivered to the receivers down the rpt 174
- Asm model any source multicast model in the asm model any sender can be a multicast source sending multicast information to a multicast group and receivers can join a multicast group identified by a group address and obtain multicast information addressed to that multicast group in this model receivers are not aware of the location of the multicast source in advance however they can join or leave the multicast group at any time 175
- Gmrp overview 175
- Multicast models 175
- Ssm model source specific multicast model in actual situations users may be interested in the multicast data only from certain specific multicast sources the ssm model provides a transmission service that allows users to specify the multicast sources they are interested in at the client side 175
- With igmpv1 or igmpv2 running on the receivers no source addresses are specified in igmpv1 or igmpv2 report messages in such cases static ssm mappings must be configured on the router to map the g information carried in these reports to the g include s1 s2 information 175
- With igmpv3 running on the receivers multicast source addresses are contained in igmpv3 report messages 175

- Actions 179
- An igmp snooping enabled switch deems that all its ports on which igmp general 179
- How igmp snooping works 179
- Leads the switch to a layer 3 multicast device rather than a port on a router 179
- Port aging timers in igmp snooping and related messages and 179
- Queries with the source address other than 0 or pim hello messages are received to be router ports 179
- Table 1 179
- The port aging mechanism of igmp snooping works only for dynamic ports a static port will never age out 179
- When receiving a general query 179
- Whenever mentioned in this document a router port is a port on the switch that 179
- A switch does not forward an igmp report through a non router port the reason is as follows due to the igmp report suppression mechanism if the switch forwards a report message through a member port all the attached hosts listening to the reported multicast address will suppress their own reports upon hearing this report and this will prevent the switch from knowing whether any hosts attached to that port are still active members of the reported multicast group 180
- When receiving a leave group message 180
- When receiving a membership report 180
- Processing of multicast protocol messages 181
- Qtech software configuration manual 182
- Table 2 3 igmp snooping messages 182
- An igmp snooping enabled ethernet switch judges whether the multicast group exists when it receives an igmp leave packet sent by a host in a multicast group if this multicast group does not exist the switch will drop the igmp leave packet instead of forwarding it 183

- The client sends a request to the dhcp server to release the dhcp information and the client deactivates its ip address as clients usually do not know when users may unplug them from the network the protocol does not mandate the sending of dhcp release 208
- Dhcp packet format 209
- Note the ip addresses offered by other dhcp servers if any are not used by the dhcp client and are still available to other clients 209
- Obtaining ip addresses dynamically 209

- Introduction to stp 250
- Protocol packets of stp 250
- Why stp 250
- How stp works 251
- Note all the ports on the root bridge are designated ports 251
- Principle for configuration bpdu comparison the configuration bpdu that has the lowest root bridge id has the highest priority if all the configuration bpdus have the same root bridge id they will be compared for their root path costs if the root path cost in a configuration bpdu plus the path cost corresponding to this port is s the configuration bpdu with the smallest s value has the highest priority if all configuration bpdu have the same root path cost they will be compared for their designated bridge ids then their designated port ids and then the ids of the ports on which they are received the smaller the id the higher message priority 253
- Table 2 selection of the optimum configuration bpdu 253
- When the network topology is stable only the root port and designated ports forward traffic while other ports are all in the blocked state they only receive stp packets but do not forward user traffic 254
- In rstp a newly elected designated port can enter the forwarding state rapidly if this condition is met the designated port is an edge port or a port connected with a point to point link if the designated port is an edge port it can enter the forwarding state directly if the designated port is connected with a point to point link it can enter the forwarding state immediately after the device undergoes handshake with the downstream device and gets a response 257
- In rstp a newly elected root port can enter the forwarding state rapidly if this condition is met the old root port on the device has stopped forwarding data and the upstream designated port has started forwarding data 257

- To facilitate description the spanning tree computing process in this example is simplified while the actual process is more complicated 257
- Why mstp 257
- Some concepts in mstp 258
- Currently the device is not capable of recognizing boundary ports when the device interworks with a third party s device that supports boundary port recognition the third party s device may malfunction in recognizing a boundary port 259
