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.
Views
Interface view
Predefined user roles
network-admin
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.
To solve this problem, use this command to add relevant interfaces to a mesh group. An interface in a
mesh group only floods a received LSP or a generated LSP to interfaces not in the same mesh group.
You can also use this command to block an interface. A blocked interface sends LSPs only after receiving
LSP requests.
The mesh-group feature takes effect only on point-to-point links.
Examples
# Add the frame relay subinterface Serial2/1.1 to mesh-group 3.
