Modifying global IS-IS parameters

You can modify, disable, or remove global IS-IS parameters without shutting down entities. Changes take effect immediately. Modifying the level capability on the global level causes the IS-IS protocol to restart.

Example

The following shows the command usage to modify various parameters.

config>router>isis#  overload timeout 500
    config>router>isis# level-capability level-1/2
    config>router>isis# no authentication-check
    config>router>isis# authentication-key raiderslost
