A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Pseudowire Emulation Edge to Edge Working Group of the IETF. Title : LDP extensions for AII reachability Author(s) : Y. Stein, L. Martini, C. Wei, S. DeLord, F. JOUNAY, P. Niger, M. Aissaoui, M. Bocci Filename : draft-ietf-pwe3-ldp-aii-reachability-03.txt Pages : 10 Date : 2009-11-23 The dynamic End-to-End Multisegment pseudowire setup requires PEs to maintain a pseudowire routing table when using FEC129. There is a requirement to automatically advertise Attachment Individual Identifiers to enable the pseudowire routing tables to be populated. Two mechanisms already exist, a BGP reachability information distribution mechanism and an IGP based one. Here we define a third solution relying on LDP. It allows for automatic advertisement of the Attachment Individual Identifier prefixes provisioned on a T-PE when this node does not run BGP or IGP. The mechanism described here runs on the T-LDP (Targeted LDP) session between the T-PE and S-PE, and is intended to complement existing PW routing mechanisms using BGP or OSPF.
