Fully-meshed point-to-point topologies suffer from a potentially large
amount of needless LSP flooding. At the trade-off of resiliency, interfaces can be
restricted from flooding received LSPs.
To configure an interface for a mesh environment, use the
following command:
configure
isis [vlan all | {vlan} vlan_name] mesh [block-none | block-all | block-group group_id]
-
To block the flooding of received LSPs altogether, use
the mesh block-all option.
-
To block the flooding of LSPs received on a specific
group of interfaces (which are those with the same mesh group ID), use the
mesh block-group group_id option.
-
To remove blocking for an interface, use the
mesh block-none option.
