[c-nsp] Redistributing default route across MPLS WAN

[jason evans]

Seems like this should be easy, but I'm having no success ...

The problem is the SF office has a flaky internet connection that
Verizon is looking into (we all know how long that can take). Good
news is that there is an MPLS Multilink PPP connection back into the
Verizon MPLS network and SF can reach NY and other offices (via
private IP's) on the MPLS bone just fine.

My objective is to route all traffic, Internet included for the time
being, through the MPLS link to NY, into the NY LAN and out of the NY
Firewall. All this has been set up and everything works fine IF the
NY-PPP router has a specific entry for the external network I'm trying
to reach. So for instance if I put a static route entry in NY-PPP for
1.2.3.4 255.255.255.255 NY-FW it works fine and from SF I can ping to
this external host. However, if I don't have a static entry in NY-PPP
then the packet gets dropped after it traverses the Verizon MPLS
first-hop neighbor. The DR on NY-PPP is the NY-FW btw.

Obviously, I'm not redistributing my entire BGP table into my LAN, so
how do I "trick" the NY-PPP into accepting the packets without a
specific entry being advertised to my SF MPLS router?

Any guidance is greatly appreciated!
