Configuring Point-to-Point Pseudowire Redundancy
• Use the never keyword to specify that the secondary pseudowire does not fall back to the primary pseudowire if
the primary pseudowire becomes available again, unless the secondary pseudowire fails.
Step 5 exit
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-pwc)# exit
RP/0/RSP0/CPU0:router(config-l2vpn)#
Exits the current configuration mode.
Step 6 xconnect group group-name
Example:
RP/0/RSP0/CPU0:router(config-l2vpn)# xconnect group A
RP/0/RSP0/CPU0:router(config-l2vpn-xc)#
Enters the name of the cross-connect group.
Step 7 p2p { xconnect-name }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-xc)# p2p xc1
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p)#
Enters a name for the point-to-point cross-connect.
Step 8 neighbor { A.B.C.D } { pw-id value }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p)# neighbor 10.1.1.2 pw-id 2
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p-pw)#
Configures the pseudowire segment for the cross-connect.
Step 9 pw-class { class-name }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p-pw)# pw-class path1
Configures the pseudowire class name.
Step 10
backup { neighbor A.B.C.D } { pw-id value }
Example:
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p-pw)# backup neighbor 10.2.2.2 pw-id 5
RP/0/RSP0/CPU0:router(config-l2vpn-xc-p2p-pw-backup)#
Configures the backup pseudowire for the cross-connect.
