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.
Dell Networking OS accepts confederation EBGP peers without a LOCAL_PREF attribute. The software sends
AS_CONFED_SET and accepts AS_CONFED_SET and AS_CONF_SEQ.
If a local-as is configured, BGP does not allow for the configuration of BGP confederation. Similarly, if BGP
confederation is configured, then BGP does not allow the configuration of local-as.
