116 CHAPTER 5: IP ROUTING PROTOCOL OPERATION
Setting the IS-IS to Use the MD5 Algorithm That Is Compatible With Other
Vendors’
You must configure this command when the switch needs to
authenticate the devices of other vendors using MD5 algorithm in IS-IS.
Perform the following configurations in IS-IS view.
By default, the system uses the MD5 algorithm in IS-IS that is compatible with the
3Com algorithm.
Setting the Mesh Group of the Interface
On NBMA network, the interface of a router will flood the received LSP to other
interfaces. However, this processing method applied to a network with higher
connectivity and several p2p links will cause repeated LSP flooding and waste
bandwidth.
To avoid this problem, you can configure several interfaces into a mesh group. The
interface will flood outside the group only.
Perform the following configurations in VLAN interface view..
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.
The
IS-IS configuration tasks on the interface are finished. The following sections
discuss how to configure other parameters of IS-IS.
Setting the Router Type
Users can set the level for the current router; based upon the location of the router
in the network, Level-1 (intra-domain router), Level-2 (inter-domain router) and
Level-1-2 (intra-domain router as well as inter-domain router) can be selected.
Perform the following configurations in IS-IS view..
By default, the router type is level-1-2.

Operation Command
Set the IS-IS to use the MD5 algorithm that is
compatible with the algorithm of another
vendor
