fast-reroute timer
Use fast-reroute timer to configure the interval for selecting an optimal bypass tunnel.
Use undo fast-reroute timer to restore the default.
Syntax
fast-reroute timer interval
undo fast-reroute timer
Default
The optimal bypass tunnel selection interval is 300 seconds.
Views
MPLS TE view
Predefined user roles
network-admin
Parameters
interval: Specifies the interval for selecting an optimal bypass tunnel, in the range of 0 to 604800
seconds. If you set the interval to 0 seconds, RSVP does not periodically select an optimal bypass tunnel.
Usage guidelines
If you have specified multiple bypass tunnels for a primary CRLSP, MPLS TE selects an optimal bypass
tunnel to protect the primary CRLSP. Sometimes, a bypass tunnel might become better than the current
optimal bypass tunnel because, for example, the reservable bandwidth changes. Therefore, MPLS TE
must poll the bypass tunnels periodically to update the optimal bypass tunnel.
NOTE:
A
fter traffic is switched from the primary CRLSP to a bypass tunnel, MPLS TE no lon
g
er periodically selects
optimal bypass tunnels for the primary CRLSP.
Examples
# Set the optimal bypass tunnel selection interval to 120 seconds.

interface tunnel-bundle
Use interface tunnel-bundle to create a tunnel bundle interface in load sharing mode, and enter tunnel
bundle interface view.
Use undo interface tunnel-bundle to delete a tunnel bundle interface.
