Huawei AR1200 Series Enterprise Routers
Configuration Guide - VPN
Context
By default, no router ID is configured for a BGP VPN instance IPv4 address family, and the
BGP router ID is used. This makes different BGP VPN instance IPv4 address families on the
same device have the same router ID. In some cases, different router IDs need to be configured
for different BGP VPN instance IPv4 address families. For example, BGP peer relationships
need to be established between different BGP VPN instance IPv4 address families on the same
PE.
There are two methods to configure a router ID for a BGP VPN instance IPv4 address family.
