Configuring LSP
Parameters
An IS-IS router periodically advertises all the local LSPs to maintain the LSP
synchronization in the entire area.
A LSP is given an aging time when generated by the router. When the LSP is
received by another router, its aging time begins to decrease. If the receiving
router does not get the update for the LSP within the aging time, the LSP will be
deleted from the LSDB.
The router will discard a LSP with incorrect checksum. You can configure the
router to ignore the incorrect checksum, which means a LSP will be processed
even with an incorrect LSP checksum.
On the NBMA network, the router will flood a new LSP received from an interface
to other interfaces. This can cause the LSP reflooding on the high connectivity
networks. To avoid this problem, you can make a mesh group of interfaces. The
interface in this group will only flood the new LSP to interfaces outside the mesh
group.
Follow these steps to configure the LSP parameters:
