• Configuring gvrp 216
• Part 9 216
• Gvrp garp vlan registration protocol is a garp generic attribute registration protocol application that allows registration and deregistration of vlan attribute values and dynamic vlan creation 217
• Overview 217
• The configuration may seem easy in this situation however for a larger or more complex network such manual configuration would be time consuming and fallible gvrp can be used to implement dynamic vlan configuration with gvrp the switch can exchange vlan configuration information with the adjacent gvrp switches and dynamically create and manage the vlans this reduces vlan configuration workload and ensures correct vlan configuration 217
• Without gvrp operating configuring the same vlan on a network would require manual configuration on each device as shown in figure 1 1 switch a b and c are connected through trunk ports vlan 10 is configured on switch a and vlan 1 is configured on switch b and switch c switch c can receive messages sent from switch a in vlan 10 only when the network administrator has manually created vlan 10 on switch b and switch c 217

• Department a and department b of a company are connected using switches offices of one department are distributed on different floors as shown in figure 3 1 the network topology is complicated configuration of the same vlan on different switches is required so that computers in the same department can communicate with each other 223
• Network requirements 223
• The two departments are in separate vlans to make sure the switches only dynamically create the vlan of their own department you need to set the registration mode for ports on switch 1 4 as fixed to prevents dynamic registration and deregistration of vlans and allow the port to transmit only the static vlan registration information 223
• To configure dynamic vlan creation on the other switches set the registration mode of the corresponding ports as normal to allow dynamic registration and deregistration of vlans 223
• To reduce manual configuration and maintenance workload gvrp can be enabled to implement dynamic vlan registration and update on the switches 223
• When configuring gvrp please note the following 223
• Using the gui 224
• Using the cli 228

• A member port is a port on snooping switch that is connecting to the host 235
• A router port is a port on snooping switch that is connecting to the igmp querier 235
• A snooping switch indicates a switch with igmp snooping enabled the switch maintains a multicast forwarding table by snooping on the igmp transmissions between the host and the querier with the multicast forwarding table the switch can forward multicast data only to the ports that are in the corresponding multicast group so as to constrain the flooding of multicast data in the layer 2 network 235
• An igmp querier is a multicast router a router or a layer 3 switch that sends query messages to maintain a list of multicast group memberships for each attached network and a timer for each membership 235
• Demonstrated as below 235
• Igmp querier 235

• Overview 456
• Supported features 456
• An option 82 has two sub options namely the agent circuit id and agent remote id the information that the two sub options carry depends on the settings of the dhcp relay agent and are different among devices from different vendors to allocate network addresses using option 82 you need to define the two sub options on the dhcp relay agent and create a dhcp class on the dhcp server to identify the option 82 payload 457
• Option 82 457
• Option 82 is called the dhcp relay agent information option it provides additional security and a more flexible way to allocate network addresses compared with the traditional dhcp 457
• Table 1 1 and table 1 2 show the packet formats of the agent circuit id and agent remote id respectively 457
• Tp link switches preset a default circuit id and remote id in tlv type length and value format you can also configure the format to include value only and customize the value 457
• When enabled the dhcp relay agent can inform the dhcp server of some specified information of clients by inserting an option 82 payload to dhcp request packets before forwarding them to the dhcp server so that the dhcp server can distribute the ip addresses or other parameters to clients based on the payload in this way option 82 prevents dhcp client requests from untrusted sources besides it allows the dhcp server to assign ip addresses of different address pools to clients in different groups 457
• Dhcp l2 relay 460
• Unlike dhcp relay dhcp l2 relay is used in the situation that the dhcp server and clients are in the same vlan in dhcp l2 relay in addition to normally assigning ip addresses to clients from the dhcp server the switch can inform the dhcp server of some specified information such as the location information of clients by inserting an option 82 payload to dhcp request packets before forwarding them to the dhcp server this allows the dhcp server which supports option 82 can set the distribution policy of ip addresses and other parameters providing a more flexible way to distribute ip addresses 460

• Before configuring dhcp interface relay create two dhcp ip pools on the dhcp server for the two departments respectively then create static routes or enable dynamic routing protocol like rip on the dhcp server to make sure the dhcp server can reach the clients in the two vlans 494
• Configuration scheme 494
• Configure 802 q vlan on the dhcp relay agent add all computers in the marketing department to vlan 10 and add all computers in the r d department to vlan 20 494
• Configure dhcp interface relay on the dhcp relay agent enable dhcp relay globally and specify the dhcp server address for each vlan 494
• Create vlan interfaces for vlan 10 and vlan 20 on the dhcp relay agent 494
• In the given situation the dhcp server and the computers are isolated in different network segments so the dhcp requests from the clients cannot be directly forwarded to the dhcp server to assign ip addresses in two different subnets to two departments respectively we recommend you to configure dhcp interface relay to satisfy the requirement 494
• In this example the dhcp server is demonstrated with t1600g 52ts and the dhcp relay agent is demonstrated with t1600g 28ts this section provides configuration procedures in two ways using the gui and using the cli 494
• The overview of the configurations are as follows 494

• Interface helper address 514

• Local proxy arp is similar with proxy arp as shown below two hosts are in the same vlan and connected to vlan interface 1 but port 1 0 1 and port 1 0 2 are isolated on layer 2 in this case both of the hosts cannot receive each other s arp request so they cannot communicate with each other because they cannot learn each other s mac address using arp packets 527
• To solve this problem you can enable local proxy arp on the layer 3 interface and the interface will respond the arp request sender with its own mac address after that the arp request sender sends packets to the layer 3 interface and the interface forwards the packets to the intended device 527
