I need your advice ;)
I've an hub-2spokes topology, and the Customer has to implement a primary link MPLS with a provider, and a backup link MPLS with another ISP. All sites have an isolate routing process ospf (area 0) and two CE, one for each link.
So, depending that, at the moment, a load balancing solution is not a 'must', but maybe a 'nice to have', I'm thinking about these scenarios:
a) CE-PE iBGP
b) CE-PE OSPF (superbackbone for primary link; for the backup link I could use a traditional OSPF-BGP redistribution, so we have LSA3 from primary, and LSA5 from backup)
Any advice will be appreciated
Andrea, yes thats correct its not applicable for OSPF in this scenario where the down bit would take care of not advertising that route back. Its was more of a generic statement for any protocol used, to avoid suboptimal routing.
