MS-PWs can be used to scale PW based networks over both a single AS, or between multiple ASs, and there is a particular need to be able to dynamically route MS-PWs through a given AS to reach PEs at or beyond the edge of the AS, where the route of the PW through each AS needs to be automatically determined. This draft proposes extensions to OSPF to enable the automatic advertisement of summarized PW FECs, thus enabling the dynamic routing of MS-PWs across an OSPF domain.}, }
