Dano,
Are you asking because you see the VLAN defined in the running-config, or because you are actually seeing it distributed in the routing tables?
This is a special VLAN that does not exist anywhere except the wired ethernet port of the MSR, for emergency use in case something happens to the unit.
The VLAN is not reachable from any other interface, and should not be propagated via AWR or OSPF.
