IS-IS CLI levels
The CLI includes various levels of commands for IS-IS.

IS-IS CLI levels
The IS-IS CLI levels are as follows:
•
A global level for the configuration of the IS-IS protocol. At this level, all IS-IS configurations at
this level apply to IPv4 and IPv6. You enter this layer using the router isis command.
•
Under the global level, you specify an address family. Address families to separate the IS-IS
configurations for IPv4 and IPv6. You enter configurations that are for a specific You enter
this level by entering the address-family command at the router isis level.
•
Under the address family level, you select a sub-address family, which is the type of routes
for the configuration. For IS-IS, you specify unicast.
NOTE
IS-IS IPv6 is currently not supported.
•
An interface level.
Global configuration level
You enter the global configuration level of ISIS by entering the following command.
BigIron RX(config)#router isis
BigIron RX(config-isis-router)#
Syntax: [no] router isis
The
(config-isis-router)#
prompt indicates that you are at the global level for IS-IS.
Configurations you enter at this level apply to both IS-IS IPv4 and IS-IS IPv6.
Address family configuration level
The BigIron RX implementation of IS-IS includes the address family configuration level. Address
families allow you to configure IPv4 IS-IS unicast settings that are separate and distinct from IPv6
IS-IS unicast settings, when IPv6 is supported.
Under the address family level, Brocade currently supports the unicast address family
configuration level only. The device enters the IPv4 IS-IS unicast address family configuration level
when you enter the following command while at the global IS-IS configuration level.
BigIron RX(config-isis-router)# address-family ipv4 unicast
BigIron RX(config-isis-router-ipv4u)#
