I am redistributing a VRF learnt route (0/0) into OSPF configured within a VRF as an external route. The OSPF domain is area 0. I have noticed a tag on the route as shown below. No tags have been set by the export policy.
{master}

This number does not mean anything to me and is not in the routing table.
Can anyone explain where this has come from?
