Configuring Multitopology for IS-IS
Multitopology is configured in the same way as the single topology for IPv4 and IPv6 address families.
However, the single- topology command is omitted, invoking the default multitopology behavior. This
task is optional.
Step 13
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-isis-if-af)# end
or
RP/0/RP0/CPU0:router(config-isis-if-af)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
Step 14

[type instance] [detail] [level {1 | 2}]
Example:
RP/0/RP0/CPU0:router# show isis interface
POS0/1/0/1
(Optional) Displays information about the IS-IS interface.
Step 15
show isis [instance instance-id] topology
[systemid system-id] [level {1 | 2}]
[summary]
Example:
RP/0/RP0/CPU0:router# show isis topology
(Optional) Displays a list of connected routers in all areas.
