Cisco Cisco IOS Software Release 12.2(14)S

In the following example, the local router is configured as a route reflector and configures the 10.0.0.100 
multihop peer as a route reflector client. A route map is created to set the advertised next hop to 
172.16.0.1. 

Router(config)# route-map NEXTHOP 

Router(config-route-map)# set ip next-hop 172.16.0.1 

Router(config-route-map)# exit 

Router(config)# router bgp 65534 

Router(config-router)# neighbor 10.0.0.100 remote-as 65412 

Router(config-router)# address-family ipv4 

Router(config-router-af)# neighbor 10.0.0.100 activate 

Router(config-router-af)# neighbor 10.0.0.100 ebgp-multihop 255 

Router(config-router-af)# neighbor 10.0.0.100 route-reflector-client 

Router(config-router-af)# neighbor 10.0.0.100 route-map NEXTHOP out 

Router(config-router-af)# end 

In the following example, the local router (route-reflector client) is configured to establish peering with 
the route reflector and to propagate the next hop unchanged: 

Router(config)# router bgp 65412 

Router(config-router)# neighbor 192.168.0.1 remote-as 65412 

Router(config-router)# address-family ipv4 

Router(config-router-af)# neighbor 192.168.0.1 activate 

Router(config-router-af)# neighbor 192.168.0.1 ebgp-multihop 255 

Router(config-router-af)# neighbor 192.168.0.1 next-hop-unchanged 

Router(config-router-af)# end
