Tip: upstream PE election (NG-MVPN)

‎12-30-2010 07:15 AM

In NG-MVPN, if an egress PE has multiple routes to a multicast source via different ingress PEs, by default it choses the PE with the highest IP address. However, sometimes people want more control over the upstream multicast hop election. This can be achieved by using the following config in the VRF: "unicast-umh-election". In this way, the normal unicast selection rules are used to determine which route to the source is best (for example, BGP local preference).
