Re: MPLS Super Backbone + Default route

Hi Gordon,
maybe the issue is on redistribution point at pe:
- in order to redistribute external ospf routers in bgp, you have to be
explicit;
- default-information originate is required inside address-family.

pe1#
router bgp 1
 address-family ipv4 vrf vpnA
   redistribute ospf 1 match external
   default-information originate

pe2#sh ip route vrf vpnA | i 0.0.0.0
B* 0.0.0.0/0 [200/1] via ..........

HTH,
-mirco.
