When this command is configured, the interface does not participate in the LFA calculation, and cannot
be elected as a backup interface.

# Disable LFA calculation on interface GigabitEthernet 2/1/1.

isis mesh-group
Use isis mesh-group to add an interface into a mesh group or block the interface.
Use undo isis mesh-group to restore the default.
Syntax
isis mesh-group { mesh-group-number | mesh-blocked }
undo isis mesh-group
Default
An interface does not belong to any mesh group and is not blocked.

Parameters
mesh-group-number: Specifies a mesh group by its number in the range of 1 to 4294967295.
mesh-blocked: Blocks the interface.
Usage guidelines
An interface not in a mesh group floods received LSPs to other interfaces. For an NBMA network with
multiple point-to-point links, this mechanism causes repeated LSP flooding and bandwidth waste.
