issue default route under mpls

[i.fontana]

Hi,

we have:

(vrf1) ce1--pe1--(bgp_mpls)--pe2--(ospf)--ce2 (vrf2)

only pe2 generate the default for ce2 and for ce1 (trough pe1 that made a redistridution on default)

ce1 and ce2 must see ONLY default route.

The problem is on pe2. Pe2 generate the default for ce1 and ce2 using a static null0. The default is correctly seen on ce1 and on ce2 but the tracert from ce1 to ce2 stop on pe2 I think because the pe2 have a null0 and null0 drop all pachet.

I think we need inject ce2 subnet on pe2 vrf "ce1" but the ce1 and pe1 routers must see ONLY the default. So we must see the specific route ONLY on vrf (ce1 and ce2) inside pe2 and not on vrf inside pe1.

I need a help to do this.

Thanks

Isacco

For your topology, it is important and compulsory for PE1 and PE2 to at least have the route for CE1 and CE2. CE1 and CE2 can use default routes.

As you described in your requirement, you will not have bi-drectional traffic flow.
