DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters IS-IS configuration submode.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router
isis purple
Step 2
Specifies link-group values. Following are the valid values:
link-group link-group-name { [
metric-offset count | maximum ] | [
Step 3
•
metric-offset: Configures the metric offset for link group. The range
is 1-16777214. The default metric offset range is between 1-63 for
narrow metric; and 1-16777214 for wide metric.
minimum-members count |
revert-members count ] }
The maximum option here sets the maximum wide metric offset.
All routers exclude this link from their SPF.
•
minimum-members: Configures the minimum number of members
in the link group. The range is 2-64.
•
revert-members: Configures the number of members after which
to revert in the link group. The range is 2-64.
A link-group is only active after the minimum-members and
offset-metric are configured in the profile. The revert-members
is default to minimum-members if it is not configured.
