•
Exchange of BGP routes of a VPN instance is the same as that of ordinary BGP routes.
• The BGP configuration task in BGP VPN instance view is the same as that in BGP view. For more
information, see
Layer 3—IP Routing Configuration Guide.
• For information about BGP peer and BGP peer group configuration, see Layer 3—IP Routing
Configuration Guide. This chapter does not differentiate between peer and peer group.

Configuring routing features for BGP VPNv4 subaddress family
With BGP VPNv4 subaddress family, there are a variety of routing features that are the same as those for
BGP IPv4 unicast routing. You can select any of the features as required.
Configuring common routing features for all types of subaddress families
For VPN applications, BGP address families include BGP VPN-IPv4 address family, BGP-L2VPN address
family, and VPLS address family. Every command in the following table has the same function on BGP
routes for each type of the address families and only takes effect for the BGP routes in the address family
view where the command is executed.
Follow these steps to configure common routing features for all types of subaddress families:
