Thanks Nick, We are quite a small service provider and have just expanded our MPLS and the issue was not seen before - is it common to use an anycast address as default route destination then?
Interestingly, the ME3600 PE nodes I have are actually picking the nearest RR for default so there appears to be a difference between IOS and Junos.
