Cisco IOS XR Routing Configuration Guide
Step 11
circuit-type {level-1 | level-1-2 |
level-2-only}
Example:
RP/0/RP0/CPU0:router(config-isis-if)#
circuit-type level-1-2
(Optional) Configures the type of adjacency.
• The default circuit type is the configured system type
(configured through the is-type command).
• Typically, the circuit type must be configured when the
router is configured as only level-1-2 and you want to
constrain an interface to form only level-1 or
level-2-only adjacencies.
Step 12
address-family {ipv4 | ipv6} [unicast]
Example:
RP/0/RP0/CPU0:router(config-isis-if)#
address-family ipv6 unicast
Specifies the IPv4 or IPv6 address family, and enters
interface address family configuration mode.
• This example specifies the unicast IPv6 address family
on the interface.
Step 13
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-isis-af)# end
or
RP/0/RP0/CPU0:router(config-isis-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
show isis [instance
instance-id
] interface
[
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.
