Abstract

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.
