You are troubleshooting an IS-IS adjacency issue between two routers. The 'show isis adjacency' command shows the adjacency as 'Up', but you notice that no routes are being exchanged. What is the next step to diagnose the issue?

Verify that the routers are in the same area.

Check the interface MTU to ensure it is large enough for IS-IS packets.

Reboot both routers to reset the IS-IS process.

Check the IS-IS database on both routers to see if LSPs are being received.

You are applying a routing policy to IS-IS to set the preference of a specific route. After applying the policy, you want to verify that the preference has been applied correctly. Which command would you use?

show configuration protocols isis

In a single-area IS-IS configuration, what is the purpose of setting the area address under the IS-IS protocol?

It enables IS-IS on all interfaces in the area automatically.

It specifies the IP address of the loopback interface used for router ID.

It defines the NET for the router and determines the area to which the router belongs.

It sets the metric style for the area (narrow or wide).

In Junos OS, which configuration statement is required to enable IS-IS on a specific interface?

set routing-options isis interface ge-0/0/0.0

set protocols isis interface ge-0/0/0.0

set interfaces ge-0/0/0 unit 0 family iso

set protocols isis level 1 interface ge-0/0/0.0
