Generic Associated Channel Advertisement Protocol IETF 82 November 2011 MPLS MPLS Generic Associated Channel Advertisement Protocol draft-fbb-mpls-gach-adv-00 Dan Frost danfrost@cisco.com Stewart Bryant stbryant@cisco.com Matthew Bocci matthew.bocci@alcatel-lucent.com

G-ACh Advertisement Protocol Simple protocol for one-way advertisement of application-specific data Fundamental use-case: a link-layer-agnostic equivalent to Ethernet’s Link Layer Discovery Protocol (LLDP) for MPLS networks Gives network operators an easy way to see basic information about adjacent nodes, and verify the network topology Bootstrap capability: next-hop Ethernet address determination, MCC/SCC setup, … Can be used to advertise device capabilities and configuration parameters, alerting the operator of mismatches: link-layer settings, MTU, OAM, …

Questions 82 Do operators find this functionality useful? Does the WG want to pursue this work? 82
