User Manual

Chapter 1. Commands for Routing Policy 13

www.qtech.ru

 Parameter: <map_name> is the name of route-map, permit sets route-map matching

mode to permit mode, deny sets route-map matching mode to permit mode (set sub

will not be executed under this mode), <sequence_num> is the route-map sequence

number, ranging between 1～65535.

 Default: None

 Command Mode: Global Mode

 Usage Guide: A route-map may consist of several nodes each of which is a check unit.

The check sequence among nodes is identified by sequence-number. “permit” means

the node filter will be passed if all match subs are obtained by current route and then

further all the set sub of this node will be executed without entering the check in the

next node; if the match subs can not be met, the proceed to the check in next node.

Relation among different node should be “or”, namely one node check passed then the

route filter is passed when the switch checks each node in turn in the route-map.

 Attentions should be paid on that at least one node match mode should be “permit”

when more than one node is defined. When a route-map is used for filtering routing

messages, if certain routing message can not pass any node check, then it is considered

denied by the route-map. If all nodes in the route-map are set to deny mode, then all

routing message should not be able to pass that route-map.

 Example:

 Switch#config terminal

 Switch(config)#route-map r1 permit 5

 Switch(config-route-map)#match as-path 60

 Switch(config-route-map)#set weight 30

1.15 set aggregator

 Command: set aggregator as <as-number> <ip_addr>

 no set aggregator as [<as-number> <ip_addr>]

 Function: Assign an AS number for BGP aggregator. The “no set aggregator as [<as-

number> <ip_addr>]” deletes this configuration.

 Parameter: <as-number > is the AS number, <ip_addr> is the ip address of the

aggregator shown in decimal notation.

 Command Mode: route-map mode

 Usage Guide: To use this command, one match clause should at first be defined.

 Example:

 Switch#config terminal

 Switch(config)#route-map r1 permit 5

 Switch(config-route-map)#set aggregator as 200 10.1.1.1
