Peer Ip-Prefix Export - 3Com 8807 Command Reference Manual

LDP Configuration Commands 737
In BGP view and VPN-instance sub-address family view, when adding a peer to an
external group out of an AS, you need to specify an AS number. When adding a
peer to an internal group or an external group in an AS, the AS number is not
needed.
A peer must have been added in a group in BGP view before it can be added to
another group in multicast sub-address family view or VPNv4 sub-address family
view.
In different address families, one peer can be in different groups and one group
may have different peers.
Example
# Add the peer with IP address 10.1.1.1 to the peer group test. In this example,
the peer group is IBGP peer by default, thus you need not to specify the AS
number when adding peers.
[3Com-bgp] ipv4-family vpnv4
[3Com-bgp-af-vpn] peer 10.1.1.1 group test
