IS-IS Configuration Grouping
Cisco IOS XR groups all of the IS-IS configuration in router IS-IS configuration mode, including the portion
of the interface configurations associated with IS-IS. To display the IS-IS configuration in its entirety, use
the show running router isis command. The command output displays the running configuration for all
configured IS-IS instances, including the interface assignments and interface attributes.
IS-IS Configuration Modes
The following sections show how to enter each of the configuration modes. From a mode, you can enter the
? command to display the commands available in that mode.
Router Configuration Mode
The following example shows how to enter router configuration mode:
RP/0/RP0/CPU0:router# configuration
RP/0/RP0/CPU0:router(config)# router isis isp
RP/0/RP0/CPU0:router(config-isis)#
Router Address Family Configuration Mode
The following example shows how to enter router address family configuration mode:
RP/0/RP0/CPU0:router(config)# router isis isp
RP/0/RP0/CPU0:router(config-isis)# address-family
ipv4 u
nicast
RP/0/RP0/CPU0:router(config-isis-af)#
Interface Configuration Mode
The following example shows how to enter interface configuration mode:
RP/0/RP0/CPU0:router(config)# router isis isp
RP/0/RP0/CPU0:router(config-isis)# interface GigabitEthernet 0
/3/0/0
RP/0/RP0/CPU0:router(config-isis-if)#
Interface Address Family Configuration Mode
The following example shows how to enter interface address family configuration mode:
RP/0/RP0/CPU0:router(config)# router isis isp
RP/0/RP0/CPU0:router(config-isis)# interface
GigabitEthernet 0 /3/0/0
RP/0/RP0/CPU0:router(config-isis-if)# address-family ipv4 unicast
RP/0/RP0/CPU0:router(config-isis-if-af)#
