To me it boils down to for example: Primary & backup PE with per-prefix VPN label POP VPN Label 100 (for prefix A) --> port 1, mac 00-53-AA POP VPN Label 100 (for prefix A) --> backup: port 2, VPN Label 300, Transport Label 123, mac 00-53-CC POP VPN Label 200 (for prefix B) --> port 1, mac 00-53-AA POP VPN Label 200 (for prefix B) --> backup: port 2, VPN Label 400, Transport Label 123, mac 00-53-CC Vs Primary & backup PE with per-ce/NH VPN label POP VPN Label 100 (for prefix A) --> port 1, mac 00-53-AA POP VPN Label 100 (for prefix A) --> backup: port 2, VPN Label 300, Transport Label 123, mac 00-53-CC POP VPN Label 100 (for prefix B) --> port 1, mac 00-53-AA POP VPN Label 100 (for prefix B) --> backup: port 2, VPN Label 300, Transport Label 123, mac 00-53-CC adam _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
