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.
