multi-homing (VPLS Multihoming for BGP VPLS)


Hierarchy Level


Configuration of this statement tracks BGP peers, such as to prevent isolation of the PE router from the core or split brain.. If no BGP peer is available, all active interfaces for a site are deactivated.

When identical site IDs are used without configuring multihoming, a collision log message is generated at each signaling: RPD_L2VPN_SITE_COLLISION: Same site ID 2 configured on remote PE (RD and local PE in VPN 1013 (non-multihomed site 2). This is expected behavior.


In the VPLS documentation, the word router in terms such as PE router is used to refer to any device that provides routing functions.
