Additional Paths for 6VPE
This section explains how to configure the 6VPE additional path feature to enable advertising additional paths for a 6VPE prefix, over a 6VPE session.
Topology
The topology below illustrates CE1 and CE2 as customer edge routers connected to the Provider Edge routers PE1 and PE2 respectively over a non-default VRF. CE2 is advertising the IPv6 prefix 2222::2/128 over non-default VRF to PE2, PE3, and PE4 which further advertises the prefix to RR over 6VPE sessions. RR has the 6VPE prefix 2222::2/128 with 3 next-hops PE2, PE3, and PE4. In a normal scenario, RR advertises the 6VPE prefix 2222::2/128 to PE1 with only one path (the next-hop which is marked the “best”). But with 6VPE addpath configured on RR and PE1, RR can be made to advertise the 6VPE prefix with additional-paths to PE1
