Dell 9.7(0.0) manual Bgp confederation peers as-number...as-number

Related Commands

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.

If the neighbor is an eBGP neighbor, then BGP performs a check on the first AS number. In this scenario, it is mandatory that the first sequence in the AS path is of type AS_SEQUENCE or AS_CONFED_SEQUENCE (in the case of confederations). If the first entry appears as an AS_CONFED_SET and the neighbor is not in the local AS, then this is strictly a problem with the neighbor node.

This command automatically restarts the BGP instance for the configuration to take effect.
