Level: 8. (EI Mode Only Command)
A confederation can be used to reduce the internal BGP (iBGP) mesh by dividing a
large single AS into multiple subs-ASs. External peers interact with the
confederation as if it is a single AS.
Each subs-AS is fully meshed within itself and it has connections to other sub-ASs
within the confederation. The next-hop, Multi Exit Discriminator (MED), and local
preference information is preserved throughout the confederation, allowing users to
retain a single Interior Gateway Protocol (IGP) for all the autonomous systems.
Use the show ip bgp confederation command to verify your settings.
This example shows how to create a confederation in which the AS number is 20.
Specifies one or multiple AS number partitions, separated by a comma. This value
must be between 1 and 4294967295, however, for the AS TRANS, this value must
be 23456. This parameter specifies Autonomous System numbers for BGP peers
that will belong to the confederation.
None.
