Changes to VPLS signaling -02 assumed that signaling was PE-PE, therefore need only identify the VPLS instance within the PE AGI = VPN-ID, TAII = SAII = null When signaling between ASBRs, need to identify the PE as well AGI = VPN-ID, TAII = PE_addr, SAII = null Note: PE_addr is just an identifier, need not be routable For Dist. VPLS, SAII = n - this allows multiple PWs from N-PE to N-PE |
