Configuring Adjacency

host1(config)#interface atm 2/0.1
host1(config-subif)#ip router isis floor12
host1(config-subif)#exit
host1(config)#interface atm 2/1.1
host1(config-subif)#ip router isis floor12
You can override the passive-interface configuration simply by issuing the
complementary command. For example, suppose you issue the following commands
after the previous configuration:
host1(config-router)#passive-interface atm 2/0.1
host1(config-router)#exit
host1(config)#interface loopback 0
host1(config-if)#ip router isis floor12
Now IS-IS advertises the IP address of ATM 2/0.1 in its link-state PDUs, but runs only
on loopback 0 and ATM 2/1.1.
Example 2—Sets a route tag on the IS-IS passive interface configured in Example 1.
host1(config)#router isis floor12
host1(config-router)#passive-interface loopback 0 tag 12
Example 3—Sets a metric and level on the IS-IS passive interface configured in Example
1.
host1(config)#router isis floor12
host1(config-router)#passive-interface loopback 0 metric 45 level-2
Use the no version to delete the passive interface, or to remove the tag, metric, or both.
See passive-interface
You can configure the type (level) of adjacency you want to use on an IS-IS interface.
Use to specify adjacency levels on a specified interface; however, normally, you do not
need to use this command.
Configure a router as a level 1-only, a level 1–level 2 system, or a level 2-only system.
Configure some interfaces to be level 2-only for routers that are between areas. This
prevents wasting bandwidth by sending out unused level 1 hellos.
On point-to-point interfaces, the level 1 and level 2 hellos are in the same packet.
Level 1-2 is the default.
Example
host1(config-if)#isis circuit-type level-2-only
Use the no version to restore the default value, level-1-2.
