IS-IS CLI levels
FIGURE 36 IPv6 IS-IS CLI levels
The IPv6 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 separate the IS-IS
configuration IPv6 and IPv4. You enter configurations that are for a specific You enter this
level by entering the address-family command at the router IS-IS 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.
• An interface level
Global configuration level
You enter the global configuration level of IS-IS by entering the following command:
Brocade(config)#router isis
Brocade(config-isis-router)#
Syntax: 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 implementation of IPv6 IS-IS includes a new configuration level: address family. You enter IS-IS
definitions for IPv6 IS-IS under this level. Address-family allows you to create configurations for IPv6
IS-IS unicast routes that are separate and distinct from configurations for IPv4 IS-IS unicast routes.
Under the address family level, Brocade devices support the unicast address family configuration
level only. The device enters the IPv6 IS-IS unicast address family configuration level when you
enter the following command while at the global IS-IS configuration level:
Brocade(config-isis-router)# address-family ipv6 unicast
Brocade(config-isis-router-ipv6u)#
Syntax: address-family ipv6 unicast
The (config-isis-router-ipv6u)# prompt indicates that you are at the IPv6 IS-IS unicast address
family configuration level. While at this level, you can access several commands that allow you to
configure IPv6 IS-IS unicast routes.
