[c-nsp] 0/0 into an ipv4 vrf

I'm fiddling with my lab, attempting to edumacate myself on L3VPNs.  I'm trying to figure out the best way to get a default route into my test vrf.  Since I'm doing BGP between all my PEs, it seems sensible that I try to originate the default route in BGP instead of redistributing it from another protocol.  I'm having problems doing this.

- I've tried to default-information originate within the ipv4 address family, then redistribute that default from the global table into the VRF, but Cisco doesn't like bgp to bgp redistribution.
- The BGP sessions that are established between the PEs are established via the global table, not from within the ipv4 vrf address family, so I can't configure default-originate from in there either.
- I'd rather not establish sessions with other PEs from within the ipv4 vrf address family.  Other than being able to see the default route in that address family, there's really no other information that has to be in that routing table, so unless there's no other way to do what I want, I don't see a need to complicate that routing table at all.

Any ideas?  I'm sure it's possible, I'm just still a bit ignorant.

Thanks in advance.
