Configuring BGP Community and Extended-Community Advertisements
BGP community and extended-community filtering cannot be configured for iBGP neighbors. Communities
Note
and extended-communities are always sent to iBGP neighbors under VPNv4, MDT, IPv4, and IPv6 address
families.
SUMMARY STEPS
1. configure
2. router bgp as-number
3. neighbor ip-address
4. remote-as as-number
5. address-family{ipv4 {labeled-unicast | unicast | mdt | multicast | mvpn | tunnel} | ipv6
{labeled-unicast | mvpn | unicast}}
6. Use one of these commands:
7. commit

• send-community-ebgp
• send-extended-community-ebgp
Purpose
Specifies the autonomous system number and enters the BGP
configuration mode, allowing you to configure the BGP routing
process.
Places the router in neighbor configuration mode for BGP routing
and configures the neighbor IP address as a BGP peer.
Creates a neighbor and assigns a remote autonomous system number
to it.
Enters neighbor address family configuration mode for the specified
address family. Use either ipv4 or ipv6 address family keyword
with one of the specified address family sub mode identifiers.
IPv6 address family mode supports these sub modes:
• labeled-unicast
