HAPTER ONFIGURATION OMMANDS
By default, no autonomous system is configured as a member of the
confederation.
Before this command is performed, the confederation ID should be configured by
the confederation id command. Otherwise this configuration is invalid. The
configured ASs in this command are inside the confederation and each AS uses
fully meshed network. The confederation appears as a single AS to the routers
outside it.
Related command: confederation nonstandard, confederation id.
Example
