I have this setup (see pic) and it does not seem that OSPF is advertise the default route to the neighbor. I want my mpls link as the primary default gateway and my Internet link as my backup gateway with higher AD, I use default-information originate in ospf to redistribute my default gateway. But I don't see it from the core.
From the core, sh ip ro shows the last resort as 10.10.110.1. Isn't it supposed to be 10.10.100.1 (advertised via ospf from the wan router?
