Perform the following configurations in Interface view.
Table 5-16 Setting the mesh group of the interface
Add an interface to a mesh group.
Remove the interface from the mesh
group
By default, the LSP is flooded normally from the interface. When configured with the
mesh-blocked parameter, it will not flood the LSP to other interfaces.
Thus the IS-IS configuration tasks on the interface are finished. The following sections
discuss how to configure other parameters of IS-IS.
5.2.15 Setting Router Type
Users can set the levels of the current router. Based upon the position of the router, the
levels can be divided into Level-1 (intra-domain router), Level-2 (inter-domain router)
and Level-1-2 (i.e. intra-domain router as well as inter-domain router).
Perform the following configurations in IS-IS view.
Table 5-17 Setting router type
Set router type
Restore the default router type
By default, the router type is level-1-2.
5.2.16 Setting to Generate Default Route
In the IS-IS route domain, the Level-1 router only has the LSDB of the local area, so it
can only generate the routes in the local areas. But the Level-2 router has the
backbone LSDB in the IS-IS route domains and generates the backbone network
routes only. If a Level-1 router in one area wants to forward the packets to other areas,
it needs to first forward the packets to the closest Level-1-2 router in the local area
along its default route.
Perform the following configurations in IS-IS view.
