Configuring BGP4+ Confederation

Route confederation has the similar function as the route reflector.
It is to reduce the number of IBGP neighbor connections in an AS.
Route confederation allows an AS to be divided into multi sub-ASs.
IBGP routers in the AS belong to the sub-ASs respectively. IBGP is
established within the sub-ASs. EBGP is established between the
sub-ASs. The sub-AS ID is called confederation ID. Sub-ASs are
invisible to the outside world of the AS.
To configure BGP4+ confederation, perform the following steps.
bgp confederation identifier
bgp confederation peers
There are 5 BGP4+ routers in AS200, as shown in
is divided into two sub-ASs. One is defined as AS65010, which
includes R3, R5 and R6, and the other is defined as AS65020,
which includes R4 and R7.
