RE: L3VPN works, except default route

Incase y'all didn't see my gratitude for your assist in the other mail list.

Beautiful, y'all are awesome...thanks luis, michele, peter, joe, frog, Jason

This worked. (under bgp)

vrf one

rd 10.101.0.1:1

default-information originate

address-family ipv4 unicast

  redistribute ospf 1

(still wondering why I get all my ospf IA and E2 routes cleanly over to the
other pe's just fine even without matching internal external 1 2 when I
redis ospf 1 as below, any ideas)

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.

In your BGP configuration on the PE, under the address-family configuration
for the VRF receiving the default-route in OSPF. So if your VRF is
"CustomerA" for example, you might have something like this

router bgp 100
 address-family ipv4 vrf CustomerA
  default-information originate
  redistribute ospf 1

Give that a try. BGP is a bit..."interesting" when it comes to default
routing.

Thanks Joe, No I don't have that, so where would I put it? I assume it
would be in the bgp process of the pe closest to the 0/0 origin coming from
the ce correct? But where exactly in the bgp process? Would it be on a
neighbor session ? a vpnv4 neighbor session? Or in an address family level
config ?

Do you have default-information originate in your vrf BGP config? The
default route will not be redistributed without it
