Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
To accept 4-byte formats before entering a 4-byte AS number, congure your system. All the routers in the
Confederation must be 4 byte or 2 byte identied routers. You cannot mix them.
The autonomous systems congured 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.
