7.16.6 Checking the Configurations
After the parameters specifying the IPv6 IS-IS route convergence speed are set, run the following
commands to verify that the configurations are correct.

Example
Run the
display isis interface verbose
command. The command output shows that GE 6/0/0
sends Hello packets at an interval of 15 ms, the number of IS-IS Hello packets sent by the
neighbor before IS-IS should declare the neighbor is invalid is 3, the sending interval for Level-1
CSNPs is 123 ms, and the minimum sending interval for LSPs is 159 ms.
