Description (partial)

After moving an interface with multicast enabled from one VRF to another one, there is an IGMP syslog error similar to:
igmp[213]: %ROUTING-IPV4_IGMP-3-IDB_VERIFY1_ERR : VRF Te0402Te0403: Interface TenGigE0_4_0_2 has configured under context vrf0 already
No S,G state is inserted into MRIB for the affected VRF.

The interface in question must have belonged to a different VRF before it was configured under the affected VRF.
