R3303-HP 6600/HSR6600 Routers MPLS Command Reference Guide

152
A bypass tunnel cannot be used for services like VPN at the same time.
When you specify a bypass tunnel, make sure that:
• The state of the tunnel is up.
• The protected interface is not the outgoing interface in the route entries for the LSP of the bypass
tunnel.
Examples
# Use tunnel 0 as the bypass tunnel to protect the link connected to interface GigabitEthernet 2/1/1.
<Sysname> system-view
[Sysname] interface giabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] mpls te fast-reroute bypass-tunnel tunnel 0
mpls te failure-action teardown
Use mpls te failure-action teardown to enable the capability of tearing down a failed RSVP TE tunnel and
then reestablishing it.
Use undo mpls te failure-action teardown to disable the capability.
Syntax
mpls te failure-action teardown
undo mpls te failure-action teardown
Default
This capability is disabled.
Views
Tunnel interface view
Default command level
2: System level
Usage guidelines
With this capability configured, after BFD or periodic LSP tracert detects a failure of an RSVP-TE tunnel,
if RSVP does not reestablish the RSVP-TE tunnel within a specific period of time, MPLS TE will remove the
tunnel and reestablish it.
Examples
# On tunnel interface Tunnel 0, enable the capability of tearing down a failed MPLS TE tunnel and then
reestablishing the tunnel.
<Sysname> system-view
[Sysname] interface tunnel 0
[Sysname-Tunnel0] mpls te failure-action teardown
mpls te igp advertise
Use mpls te igp advertise to enable IGP to advertise the MPLS TE tunnel as a link to IGP neighbors.
Use undo mpls te igp advertise to remove the configuration.
