Parameters
min min-number: Specifies the minimum interface number for automatically created bypass tunnels. The
following matrix shows the value ranges for the min-number argument:
Hardware Value ran
g
e
MSR2000 0 to 1023
MSR3000 0 to 2047
MSR4000 0 to 4095
max max-number: Specifies the maximum interface number for automatically created bypass tunnels.
The following matrix shows the value ranges for the max-number argument:

MSR2000 0 to 1023
MSR3000 0 to 2047
MSR4000 0 to 4095
Usage guidelines
To enable the PLR to automatically create bypass tunnels, you must enable auto FRR globally by using the
auto-tunnel backup command, and then specify the interface number range for bypass tunnels by using
the tunnel-number command. The PLR uses the interface numbers in the specified range in ascending
order for the bypass tunnels.
When you use the tunnel-number command, follow these restrictions and guidelines:
• The min-number must be smaller than or equal to the max-number.
• The specified range must include less than 1000 interface numbers. Otherwise, this command
cannot be executed successfully.
• If you execute this command multiple times, the most recent configuration takes effect.
• When you execute this command, if bypass tunnels are already created automatically, make sure
the min-number is not greater than the minimum interface number used by the existing bypass
tunnels, and the max-number is not smaller than the maximum interface number used by the existing
bypass tunnels.
