Usage Information 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.

period expires. The range is 1 to 45. The default is 15 minutes.

compared to the flapping route's Penalty value. If the Penalty

value is less than the reuse value, the flapping route is once

again advertised (or no longer suppressed). The range is 1 to

20000. The default is 750.

compared to the flapping route's Penalty value. If the Penalty

be suppressed. The default is four times the half-life value. The
