By default, the system does not require password or perform authentication.
III. Setting the IS-IS to use the MD5 algorithm compatible with that of the 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 configuration in IS-IS view.
Table 20-23
Set the IS-IS to use the MD5 algorithm compatible with that of the other
vendors
Operation
Command
Set the IS-IS to use the MD5 algorithm compatible
with that of the other vendors
md5-compatible
Set the IS-IS to use the default MD5 algorithm
undo md5-compatible
By default, the system uses the MD5 algorithm in IS-IS which is compatible with that of
3Com.
20.2.17 Setting the Mesh Group of the Interface
On a 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 such problem, you can configure several interfaces into a mesh group. The
interface will flood it outside the group only.
Perform the following configuration in interface view.
