Re: L3VPN works, except default route

Sorry, I had a typo in my example: If you are redistributing OSPF running
in a VRF you would have "redistribute ospf 1 vrf CustomerA" but you get the
idea.

A few more "gotchas":

- If you are running OSPF as your IGP on the other end as well, you will
need to make sure to add "default-information originate" in the OSPF
process on the remote PE as well
- Also, don't forget to match external routes on your OSPF --> BGP
redistribution as by default they don't get pulled in.
