There is a customer requirement where hub site has dual CEs connecting to
dual CPEs which are connecting to the same PE router. The spoke site need
to connect the hub site on primary-backup mode.
Can not use the site preference in l2vpn instance since both primary and
backup sites are terminating on the same PE.
Tried testing with the two different routing instances with same RT and
Site IDs on the hub site PE. This causes l2vpn connections of both the
instances in hub PE to be up all the time [only one site in the spoke
though]. This causes layer2 loop.
Is there a fix for this?
