R21xx-HP FlexFabric 11900 MPLS Command Reference

141
tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19
characters. If no tunnel policy is specified, the default tunnel policy is used.
Usage guidelines
This command configures a backup PW for a PW to implement PW redundancy. The backup PW is used
when the primary PW fails.
To configure a static backup PW, you must specify the in-label and out-label. To configure a backup LDP
PW, there is no need to specify the in-label and out-label.
The peer LSR ID and PW ID specified for the backup PW must not both be the same as those for any VPLS
PW or any PW bound to a cross-connect.
PW redundancy is mutually exclusive from the multi-segment PW function. If you have configured two
PWs by using the peer command in cross-connect view, you cannot configure a backup PW by using the
backup-peer command in PW view, and vice versa.
Examples
# Configure a primary PW and a backup PW for the cross-connect pw2pw in the cross-connect group
vpn2. The primary PW is destined to 6.6.6.6 and has a PW ID of 100. The backup PW is destined to
7.7.7.7 and has a PW ID of 200.
