PurposeCommand or Action
of the NET differs, the system ID portion of the NET
must match exactly for all of the configured items.
Specifies the IPv6 address family and enters router address
family configuration mode.
address-family ipv6 [ unicast ]
Example:
Step 7
• This example specifies the unicast IPv6 address
family.
RP/0/RP0/CPU0:router(config-isis)# address-family
ipv6 unicast
(Optional) Configures the link topology for IPv4 when
IPv6 is configured.
single-topology
Example:
Step 8
• The single-topology command is valid only in IPv6
submode. The command instructs IPv6 to use the
RP/0/RP0/CPU0:router(config-isis-af)#
single-topology
single topology rather than the default configuration
of a separate topology in the multitopology mode.
• See the Single-Topology IPv6 Support, on page 205
for more information.
Exits router address family configuration mode, and returns
the router to router configuration mode.
exit
Example:
Step 9
RP/0/RP0/CPU0:router(config-isis-af)# exit
Enters interface configuration mode.
interface type interface-path-id
Example:
Step 10
RP/0/RP0/CPU0:router(config-isis)# interface
GigabitEthernet 0/1/0/3
(Optional) Configures the type of adjacency.circuit-type { level-1 | level-1-2 | level-2-only }
Step 11
Example:
• The default circuit type is the configured system type
(configured through the is-type command).
RP/0/RP0/CPU0:router(config-isis-if)# circuit-type
level-1-2
• 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.
Specifies the IPv4 or IPv6 address family, and enters
interface address family configuration mode.
address-family { ipv4 | ipv6 } [ unicast ]
Example:
Step 12
• This example specifies the unicast IPv4 address
family on the interface.
RP/0/RP0/CPU0:router(config-isis-if)#
address-family ipv4 unicast
commit
Step 13
(Optional) Displays information about the IS-IS interface.
show isis [ instance instance-id ] interface [ type
