SmartSwitch Router User Reference Manual 157Chapter 12: BGP Configuration GuideRouter SSR8 has the following CLI configuration:Router SSR9 has the following CLI configuration:Route Reflection ExampleIn some ISP networks, the internal BGP mesh becomes quite large, and the IBGP full meshdoes not scale well. For such situations, route reflection provides a way to alleviate theneed for a full IBGP mesh. In route reflection, the clients peer with the route reflector andexchange routing information with it. In turn, the route reflector passes on (reflects)information between clients.The IBGP peers of the route reflector fall under two categories: clients and non-clients. Aroute reflector and its clients form a cluster. All peers of the route reflector that are not partof the cluster are non-clients. The SSR supports client peers as well as non-client peers of aroute reflector.interface add ip xleapnl address-netmask 212.19.192.2/24interface create ip hobbygate address-netmask 212.19.199.62/24 portet.1.2interface create ip xenosite address-netmask 212.19.198.1/24 portet.1.7interface add ip lo0 address-netmask 212.19.192.1/30bgp create peer-group webnet type external autonomous system 64901bgp add peer-host 194.109.86.5 group webnet## Create an aggregate route for 212.19.192.0/19 with all its subnets as# contributing routes#ip-router policy summarize route 212.19.192.0/19ip-router policy redistribute from-proto aggregate to-proto bgp target-as 64901 network 212.19.192.0/19ip-router policy redistribute from-proto direct to-proto bgp target-as64901 network all restrictbgp create peer-group rtr8 type external autonomous system 64900bgp add peer-host 194.109.86.6 group rtr8
