RP/0/RP0/CPU0:router(config-isis-af)# exit
Exits router address family configuration mode, and returns the router to router configuration mode.
Step 10 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-isis)# interface HundredGigE 0/1/0/3
Enters interface configuration mode.
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 ipv4 unicast
Specifies the IPv4 or IPv6 address family, and enters interface address family configuration mode.
• This example specifies the unicast IPv4 address family on the interface.
Step 13 commit
Step 14 show isis [ instance instance-id ] interface [ type interface-path-id ] [ detail ] [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router# show isis interface HundredGigE 0/1/0/1
(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.
