[c-nsp] Why L2VPN Pseudowire Redundancy not work?

Mon Sep 2 22:03:31 EDT 2013

Hi all,

                I used this configure on PE1:

interface GigabitEthernet9/16.12

description test redundant psedowire

encapsulation dot1Q 12

xconnect 10.5.0.38 1138074000 encapsulation mpls

  backup peer 10.5.0.87 1174087000

end

                When I shutdown interface of 10.5.0.38, log on PE is ok.

267506: Sep  3 08:45:51.820 bkk: %XCONNECT-5-PW_STATUS: MPLS peer 10.5.0.38
vcid 1138074000, VC DOWN, VC state DOWN

267507: Sep  3 08:45:51.828 bkk: %XCONNECT-5-PW_STATUS: MPLS peer 10.5.0.87
vcid 1174087000, VC UP, VC state UP

                But I ping from switch that connect with PE1 not work until
I ping back from switch that connect with 10.5.0.87.

Success rate is 92 percent (927/1000), round-trip min/avg/max = 1/3/26 ms

                Why it doesn't automatic?

Thank you very much.
