a protocol that carries upper-layer data and error indications

In IS-IS routing, when is level 2 routing required?

when routing between end systems and intermediate systems

RTC(config-if)# isis circuit-type layer-2-only

RTC(config-router)# is-type level-1

RTC(config-router)# is-type level-2-only

What is the area number for the following IS-IS router configuration? RouterA(config)# router isis RouterA(config-router)# net 49.2385.A02C.025B.0001.00

49

49.2385

49.2385.A02C

A02C.025B.0001

Which two commands must be issued to initially configure a network for IS-IS? (Choose two.)

net command

isis circuit-type

ip router isis

isis metric

isis password

Observe the diagram. The IS-IS routers are not exchanging updates. What is a possible reason?

The routers are not in the same area.

The metrics do not match.

The IS-IS circuit types do not match.

The routers are not both configured as level 1 routers.

In an IS-IS environment, what is true about Level 2 routers?

responsible for routing between separate domains

responsible for routing between different areas within the same domain

responsible for routing between ISs within the same area

responsible for routing between ESs and ISs on the same subnet

Which three statements are true about IS-IS L2 routers? (Choose three.)

L2 routers have interfaces in multiple areas.

L2 routers have interfaces in a single area.

L2 routers maintain a link-state database that contains only inter-area topology information.

L2 routers are responsible for routing to end systems inside an area.

L2 routers make up the backbone of an IS-IS routing domain.

Which two statements are true about the IS-IS pseudonode LSP? (Choose two.)

It represents a LAN.

It is sent by the DIS only.

It is sent on point-to-point networks.

It is sent by L2 routers only.

It increases the number of adjacencies on a LAN.

Which configuration specifies the IP networks to be advertised by IS-IS?

a network command for each IP network address

a router isis command for each IP network address

a clns router isis command for each interface with an IP network address that must be advertised

an ip router isis command for each interface with an IP network address that must be advertised

an isis circuit-type command for each IP network address

Observe the diagram. The administrator requires the IS-IS adjacencies to authenticate so that no unauthorized routers will create adjacencies. Which interface command is required for a router to authenticate with another directly connected router before allowing the adjacency to form?

area-passwordpassword

domain-password password

area # authentication password

isis passwordpassword

Which two are likely to be a cause for IS-IS neighbor relationships to be stuck in INIT state? (Choose two.)

physical layer up, but data-link layer is down

mismatched area configurations

mismatched authentication configurations

mismatched MTU configuration

data-link layer connectivity, but no IP connectivity

Refer to the exhibit showing a network diagram and partial configuration. Two neighboring IS-IS routers are unable to form an adjacency. Which two statements identify configuration problems causing the adjacency problem? (Choose two.)

IS-IS routing not properly enabled on R1

IS-IS routing not properly enabled on R2

mismatched area configurations

mismatched authentication configurations

ES-IS adjacency settings not configured properly
