Abstract:
1. A method comprising: identifying a current topology associated with a virtual local area network (VLAN); determining whether the current topology of the VLAN is to be moved to a base topology associated with a Transparent Interconnection of Lots of Links (TRILL) protocol; and moving the current topology of the VLAN to the base topology if it is determined that the current topology of the VLAN is to be moved to the base topology, wherein when the current topology associated with the VLAN is identified as a non-base topology associated with the TRILL protocol, determining whether the current topology of the VLAN is to be moved to the base topology includes determining when the non-base topology has been partitioned, and wherein determining when the non-base topology has been partitioned includes obtaining a system-ID for at least one routing bridge (rbridge) associated with the non-base topology and determining when the system-ID is present in a broadcast graph of the base topology and missing from a broadcast graph of the non-base topology.
