Configuring the Administrative Distance for IS-IS
An administrative distance is a rating of the trustworthiness of a routing information
source, such as an individual router or a group of routers. Numerically, an
administrative distance is an integer between 0 and 255. The higher the value, the
lower the trust rating. For example, an administrative distance of 255 means the
routing information source cannot be trusted and should be ignored. The default
administrative distance for IS-IS is 115.
Use the distance command in Router Configuration mode to set the administrative
distance for the IS-IS router, as shown below:
MOT(config-isis)#distance <n>
where:
n is the IS-IS routing administrative distance from 1 to 255.
Configuring IS-IS Area or Domain Passwords
Passwords can be assigned to areas and domains. The area authentication password is
inserted in Level 1 (station router level) LSPs, CSNPs, and Partial Sequence Number
PDUs (PSNPs). The routing domain authentication password is inserted in Level 2
(the area router level) LSP, CSNP, and PSNPs.
Follow these steps to configure either area or domain authentication passwords:
• If you want to configure an IS-IS area authentication password, use the
area-password command in Router Configuration mode, as shown below:
MOT(config-isis)#area-password <password>
where:
password is the unencrypted text password that is 1-8 characters in length.
• If you want to configure an IS-IS routing domain authentication password, use
the domain-password command in Router Configuration mode, as shown below:
MOT(config-isis)#domain-password <password>
where:
password is the unencrypted text password that is 1-8 characters in length.
