Configuring Basic Features for a BGP Peer
In configuring a MBGP peer (group), you should first configure AS ID for it and
then enter the corresponding address family view to activate the association.
Perform the configurations in the following subsections in BGP view.
Creating a Peer Group
A BGP peer must belong to a peer group. Before configuring a BGP peer, you must
create a peer group to which the peer will belong.
There are two types of BGP peer groups, IBGP and EBGP. Use internal to create a
IBGP peer group. Use external to create a EBGP peer group and sub-AS peer
groups inside a confederation.
The default type of BGP peer group is internal.
Configuring the AS Number of an EBGP Peer Group
You can specify the AS number for an EBGP peer group, but an IBGP peer group
needs no AS number. When a peer group is specified with an AS number, all its
member peers inherit that AS number.
The AS number cannot be specified for a peer group which already has group
numbers. Deleting the AS number of a peer group deletes all member peers in
that group.
