Usage Information
To accept 4-byte formats before entering a 4-byte AS number, configure your
system. All the routers in the Confederation must be 4 byte or 2 byte identified
routers. You cannot mix them.
The autonomous systems configured in this command are visible to the EBGP
neighbors. Each autonomous system is fully meshed and contains a few
connections to other autonomous systems. The next hop, MED, and local
preference information is preserved throughout the confederation.
The system accepts confederation EBGP peers without a LOCAL_PREF attribute.
The software sends AS_CONFED_SET and accepts AS_CONFED_SET and
AS_CONF_SEQ.
