Patent ID: 8345697

Claim:
A routing bridge in a Transparent Interconnection of Lots of Links (TRILL) domain, comprising: a first link coupled to a first device in the TRILL domain; an Intermediate System to Intermediate System (IS-IS) Traffic Engineering (TE) module operable to: receive first configuration information from the first device; and determine that data packets received by the routing bridge need to be routed to the first device based upon the first configuration information; and a TRILL header module operable to: determine that the routing bridge is not a last RBridge in a first TRILL path field of a first TRILL header in a first data packet; and decrement a first hop count value in a first hop count field of the first TRILL header; and wherein the routing bridge is operable to: receive the first data packet; forward the first data packet to a next hop RBridge based on the first TRILL path field; receive a second data packet; and route the second data packet to the first link in response to the IS-IS TE module determining that the second packet needs to be routed to the first device.
