Usage guidelines
After you create a BGP peer in BGP-VPN instance view, the BGP routes learned from the peer are added
into the routing table of the specified VPN instance.
This command and all commands in BGP-VPN instance view are usually executed on provider edge (PE)
or Multi-VPN-Instance CE (MCE) devices to add routes learned from different sites into different VPN
instances.
Before you execute this command, use the ip vpn-instance command to create the VPN instance in
system view, and use the route-distinguisher command to configure a route distinguisher (RD) for the
VPN instance.

[Sysname-vpn-instance-vpn1] quit
