Hi everyone,
I have OSPF as a CE to PE which is up and all looks good, my PE (ASR 9001) has a load of prefixs:

I am then redistributing OSPF into BGP:
vrf A
rd 57:1
address-family ipv4 unicast
redistribute ospf 1 match internal external 1 metric 20
I can see all the intra area routes going into BGP but the E1 default isn't :
RP/0/RSP0/CPU0:POP-01-PE1#sh bgp vpnv4 unicast
Status codes: s suppressed, d damped, h history, * valid, > best
i - internal, r RIB-failure, S stale, N Nexthop-discard
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
Route Distinguisher: 57:1 (default for vrf A)

Hi,
BGP does not allow the redistribution of the default route by default. You need to use the "default-information originate" to change the default behavior.
vrf A
rd 57:1
default-information originate
address-family ipv4 unicast
redistribute ospf 1 match internal external 1 metric 20
