Information
You must configure your system to accept 4-byte formats before entering a 4-byte AS number.
All the routers in the Confederation must be 4– 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.
FTOS accepts confederation EBGP peers without a LOCAL_PREF attribute. The software sends
AS_CONFED_SET and accepts AS_CONFED_SET and AS_CONF_SEQ.
