Address Family Configuration Level; Interface Level - Dell PowerConnect B-RX Configuration Manual

IS-IS CLI levels
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)#
Syntax: address-family ipv4 unicast
The (config-isis-router-ipv4u)# prompt indicates that you are at the IPv4 IS-IS unicast
address family configuration level. While at this level, you can access several commands that allow
you to configure IPv4 IS-IS unicast settings.
NOTE
Each address family configuration level allows you to access commands that apply to that particular
address family only. To enable a feature in a particular address family, you must specify any
associated commands for that feature in that particular address family. You cannot expect the
feature, which you may have configured in the IPv4 IS-IS unicast address family, to work in the IPv6
IS-IS unicast address family unless it is explicitly configured in the IPv6 IS-IS unicast address family.
To exit from the ipv4 IS-IS unicast address family configuration level, enter the following command.
BigIron RX(config-isis-router-ipv4u)# exit-address-family
BigIron RX(config-isis-router)#
Entering this command returns you to the global IS-IS configuration level.

Interface level

Some IS-IS definitions are entered at the interface level. To enable IS-IS at the interface level, enter
the following command.
BigIron RX(config)# interface ethernet 2/3
BigIron RX(config-if-e1000-2/3)#ip router isis
Syntax: [no] ip router isis
