Configuring IS-IS
Note You must also remove any IS-IS commands configured in interface mode to completely remove all
configuration for the IS-IS instance.
You can configure the following optional parameters for IS-IS:
The following example shows how to create an IS-IS instance in a level 2 area:
switch# config t
switch(config)# router isis Enterprise
switch(config-router)# net 47.0004.004d.0001.0001.0c11.1111.00
switch(config-router)# is-type level 2
switch(config-router)# copy running-config startup-config
To clear neighbor statistics and remove adjacencies, use the following command in router configuration
mode:
Restarting an IS-IS Instance
You can restart an IS-IS instance. This clears all neighbors for the instance.
To restart an IS-IS instance and remove all associated neighbors, use the following command:
Command Purpose
distance value
Example:
switch(config-router)# distance 30
Sets the administrative distance for IS-IS. The
range is from 1 to 255. The default is 115. See the
“Administrative Distance” section on page 1-7.
log-adjacency-changes
Example:
switch(config-router)#
log-adjacency-changes
Sends a system message whenever an IS-IS
neighbor changes state.
lsp-mtu size
Example:
switch(config-router)# lsp-mtu 600
Sets the MTU for LSPs in this IS-IS instance. The
range is from 128 to 4352 bytes. The default is
1492.
maximum-paths number
Example:
switch(config-router)# maximum-paths 6
Configures the maximum number of equal-cost
paths that IS-IS maintains in the route table. The
range is from 1 to 16. The default is 4.
reference-bandwidth bandwidth-value {Mbps
| Gbps}
Example:
switch(config-router)# reference-bandwidth
100 Gbps
Sets the default reference bandwidth used for
calculating the IS-IS cost metric. The range is from
1 to 4000 Gbps. The default is 40 Gbps.
Command Purpose
clear isis [ instance-tag ] adjacency [* |
system-id
| interface ]
Example:
switch(config-if)# clear isis adjacency *
Clears neighbor statistics and removed adjacencies
for this IS-IS instance.
