I have two routers in the same AS connected to the same upstream ISP. i'm trying to use router A and its link to the internet primarily and router B and its link only for backup.
my outbound plan is to have the BGP session for link A install a route to 0.0.0.0 and if this fails then a static route with a high metric to router B will be able to carry all my traffic.
my inbound plan is to advertise my class C via both BGP links however router B is setting the metric to 200 via a routemap.
On route A The ISP is only sending the origin route (0.0.0.0/0) but they are also withdrawing lots of routes as the topology of the internet changes. I'm not sure if this is interfering with my 0.0.0.0/0 but i just don't see where it is withdraw in the debugs yet sh ip bgp stats say 1 route received and 1 withdrawn.
I have tried a number of configurations but each of them usually end up with either a) the incoming route is blocked by my own route map or b) the route is received then withdrawn.
how do i get their origin route to stick in my route tables?
Thanks in advance,
