Parameters
seconds: Specifies the period of time after which an unused bypass tunnel is removed, in the range of
300 to 604800 seconds. You can also set this argument to 0, which means not to remove unused bypass
tunnels.
Usage guidelines
An automatically created bypass tunnel can protect multiple primary CRLSPs. A bypass tunnel is unused
when all primary CRLSPs protected by the bypass tunnel are removed. When a bypass tunnel is unused
for the period of time configured by this command, MPLS TE removes the bypass tunnel to release the
occupied bandwidth and tunnel interface number.
Configure a removal timer according to your network conditions, with the following considerations:
• Save resources—If the timer value is too big, unused bypass tunnels occupy bandwidth and
interface numbers for a long time.
• Keep network stability—If the timer value is too small, bypass tunnels might be set up and removed
frequently.
Examples
# Configure the removal timer for unused bypass tunnels to 60000 seconds (100 minutes).
