13.2.7 Configuring advertised route filters

Points to note

The example below shows how to set the priority of advertised BGP4 routes by using route-map and specifying the conditions and settings.

Command examples

1. (config)# ip prefix-list MY_NET_1 seq 10 permit 192.169.10.0/24

   (config)# ip prefix-list MY_NET_2 seq 10 permit 192.169.20.0/24

   (config)# route-map SET_EXT_OUT permit 10

   (config-route-map)# match ip address prefix-list MY_NET_1

   (config-route-map)# set metric 120

   (config-route-map)# exit

   (config)# route-map SET_EXT_OUT permit 20

   (config-route-map)# match ip address prefix-list MY_NET_2

   (config-route-map)# exit

   Sets 120 in the MED attribute when the destination network is 192.169.10.0/24.

   Allows route advertisements to be sent also to destination network 192.169.20.0/24.
