peer advertise-large-community (BGP-EVPN address family view) (group)

Function

The peer advertise-large-community command enables the function to advertise routes carrying the large-community attribute to a BGP EVPN peer group.

The undo peer advertise-large-community command disables the function to advertise routes carrying the large-community attribute to a BGP EVPN peer group.

By default, a device does not advertise routes carrying the large-community attribute to a BGP EVPN peer group.

Format

peer peerGroupName advertise-large-community

undo peer peerGroupName advertise-large-community

Usage Guidelines

Usage Scenario

To enable the function to advertise routes carrying the large-community attribute to the BGP EVPN peer, run the peer advertise-large-community command. If a device is enabled to advertise the routes carrying the large-community attribute to a BGP EVPN peer group, all the BGP EVPN peers in the peer group inherit this configuration. This simplifies the application of a route-policy and facilitates route maintenance and management.

Prerequisites

A route-policy has been used to define the large-community attribute.
