Hi Everyone,
We typically use OSPF (CE/PE) so customer can advertise routes into their VRF -
We have issues with failover (When customer site has 2 links) but the links go
to different PE"s of ours (We only have agg's from carriers on certain PE's)..
eg.
Customer(vrf) has a site(foo) connected to PE A + B (PE B is "failover" link)
Same customer has another site(bar) connected to PE B.
Traffic from site "bar" to "foo" will go via PE B, which is not what we
want...we have manipulated this to work via longer subnets (i.e. failover link
advertising a /23 instead of a /24), but this isnt always feasible.
Would BGP(Instead of OSFP) help in this situation...i.e. Can we manipulate how
the routes are advertised(PE A/B) within the vrf more easily if the CE
advertises via BGP vs OSPF? Or any other suggestions?
Cheers
