I have a working MPLS network but when a new VRF is added one router
refuses to install the default received from an Ebgp peer.
Below is the simple part if the VRF config
ip vrf test
rd 60000:1009
route-target export 60000:1009
route-target import 60000:1009
router bgp 60000
neighbor etc etc
address-family ipv4 vrf test
neighbor 10.238.165.125 remote-as 60000
neighbor 10.238.165.125 version 4
neighbor 10.238.165.125 activate
neighbor 10.238.165.125 send-community
no auto-summary
no synchronization
exit-address-family
routes in the vrf look fine

I can force a route to be advertised as I have done with 1.1.1.1 using a
null route.
Is the default route not being installed due to the cef drop or
something else?
Driving me nuts everything works but not a default route.
