Configuring ISIS properties on an interface

This section describe the IS-IS parameters for an interface.

Disabling and enabling IS-IS on an interface

In addition to enabling IS-IS globally, you also must enable the protocol on the individual interfaces
connected to ISs or ESs. To enable IS-IS locally on specific interfaces, enter commands such as the
following.
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-1/1)# ip router isis
BigIron RX(config-if-1/1)# exit
BigIron RX(config)# interface ethernet 1/2
BigIron RX(config-if-1/2)# ip router isis
These commands enable IS-IS on ports 1/1 and 1/2. The NET configured above (at the IS-IS
configuration level) applies to both interfaces.
Syntax: [no] ip router isis

Disabling or re-enabling formation of adjacencies

When you enable IS-IS on any type of interface except a loopback interface, the interface also is
enabled to send advertisements and form an adjacency with an IS at the other end of the link by
default. Adjacency formation and advertisements are disabled by default on loopback interfaces.
You can enable or disable adjacency formation and advertisements on an interface.
NOTE
The BigIron RX advertises an IS-IS interface to its area regardless of whether adjacency formation is
enabled.
To disable IS-IS adjacency formation on an interface, enter commands such as the following.
BigIron RX(config)# interface ethernet 2/8
BigIron RX(config-if-e1000-2/8)# isis passive
This command disables IS-IS adjacency formation on port 2/8. The device still advertises this IS-IS
interface into the area, but does not allow the port to form an adjacency with the IS at the other end
of the link.
Syntax: [no] isis passive
