11.7.2 Configuration example 1. Route-map for BGP
Objective:
Assign community for routing information coming from AS 20:
First, do the following:
Configure BGP with AS2500 on ESR router;
Establish neighboring with AS20.
Solution:
Create a policy:
esr# configure
esr(config)# route-map from-as20
Create rule 1:
esr(config-route-map)# rule 1
If AS PATH contains AS20, assign community 20:2020 to it and exit:
esr(config-route-map-rule)# match as-path contain 20
esr(config-route-map-rule)# action set community 20:2020
esr(config-route-map-rule)# exit
esr(config-route-map)# exit
In AS2500 BGP process, enter neighbor parameter configuration:
esr(config)# router bgp 2500
esr(config-bgp)# neighbor 185.0.0.2
esr(config-bgp-neighbor)# address-family ipv4 unicast
Map the policy to routing information:
esr(config-bgp-neighbor-af)# route-map from-as20 in
