3Com Switch 8800 Family Configuration Guide

Configuring Integrated IS-IS 353
Setting IS-IS area or IS-IS routing domain authentication password
Users can configure the IS-IS area or the IS-IS routing domain with authentication
password.
If area authentication is needed, the area authentication password will be
encapsulated into the level-1 LSP, CSNP and PSNP packets, in the specified mode.
If other routers in the same area also have started the area authentication, their
authentication modes and passwords must be identical to those of their
neighbors, so that they can work normally. Similarly, for domain authentication,
the password will also be encapsulated into the level-2 LSP, CSNP and PSNP
packets in the specified mode. If the routers in the backbone layer (level-2) also
need domain authentication, their authentication mode and password must be
identical to those of their neighbors.
Note that the passwords for authentication of the routers on the same network
segment must be identical.
Perform the following configurations in IS-IS view.
By default, the system does not require password or perform authentication.
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.
By default, the system uses the MD5 algorithm in IS-IS which is compatible with
that of 3Com.
