Here's the sample scenario:
- plain MPLS network (MPBGP + OSPF) with VRF VPNs
- VRF XXX configured say on PE1,PE2,PE3
- PE1 and PE2 are colocated in the same site: there is a a transit vlan to communicate with a couple of firewalls, mapped to VRF XXX; no CEs, just HSRP/VRRP and static routic redistributed in MPBGP
How can I force PE3 (remote site) to choose PE1 as best path to reach the Firewalls, for the single VRF XXX ?
Hope it's clear, thanks a lot
your findings are correct not all route-map statements are acceptable in this direction.
In this case you need to apply the route-map outbound on PE1, in this way you rise the local-preference at the origin PE.
Hope to help
