So something like
CE---PE1----PE2---P---( cloud )
^ ^
cust PE |
agg PE
??
Thats the idea linewrap is evil ;o).
If you're talking a vrf-lite-like scenario, then that means packets
are going from PE1 to PE2 unlabeled. If that's the case, they'll
follow the default route just like any other route. If you're talking
about label exchange of some sort between PE1 and PE2, there's a few
ways you can do that; we'd have to talk about more specifics, but in
general there's no provisions that a default route is treated
differently than any other route.
We are looking at label exchange rather than matching VRFs on both the
PE's. Mind you that might be an idea ...... :o).
Maybe you could tell me a little more about the label exchange scenario
between the two PE's. We do not want to run OSPF to the second PE (PE1)
as we are conecerned about OSPF stability. Just as a ball park figure
we might be talking 700 PE1's. Maybe you could explain "no provisions
that a default route is treated differently than any other route" in
the above context. Any comments most welcome as my head hurts at this stage.

Kevin
