The following example congures ORF in send mode.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 activate
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 prefix-list myprefixlist in
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 capability orf prefixlist send
The following example congures ORF in both send and receive modes.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 activate
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 prefix-list myprefixlist in
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 capability orf prefixlist
Conguring BGP4+ confederations
BGP4+ confederations, composed of multiple subautonomous systems, can be created.
1. Enter the congure terminal command to access global conguration mode.
device# configure terminal
2. Enter the router bgp command to enable BGP routing.
device(config)# router bgp
3. Enter the local-as command to congure the autonomous system number (ASN) in which your device resides.
device(config-bgp-router)# local-as 65520
4. Enter the confederation identier command and specify an ASN to congure a BGP confederation identier.
device(config-bgp-router)# confederation identifier 100
5. Enter the confederation peers command and specify as many ASNs as needed to list all BGP peers that will belong to the
confederation.
device(config-bgp-router)# confederation peers 65520 65521 65522
The following example creates a confederation with the confederation ID “100” and adds three subautonomous systems to the
confederation.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 65520
device(config-bgp-router)# confederation identifier 100
device(config-bgp-router)# confederation peers 65520 65521 65522
Dening a community ACL
A BGP community ACL can be congured, and BGP community attributes set in a route map instance.
1. Enter the congure terminal command to access global conguration mode.
device# configure terminal
