Routers R1 and R2 reside in AS 65530, which is multihomed to the Internet. A network engineer expects devices in the AS to use R2 to access the Internet, but they are using R1 as the exit point from the AS. Which action corrects the problem?
Routers R1 and R2 reside in AS 65530, which is multihomed to the Internet. A network engineer expects devices in the AS to use R2 to access the Internet, but they are using R1 as the exit point from the AS. Which action corrects the problem?
Change the route map direction in the neighbor statement to out.
Configure the route map with a local preference of 200 or higher.
Remove the neighbor statements from the address family configuration and activate the neighbor globally on R1.

QoS and Traffic Engineering
Refer to the exhibit. A network engineer applied configuration on R1 to summarize all ISIS routes, but R2 is still receiving specific routes from R1. The engineer has confirmed that both routers are configured with the correct summarization configuration, but R1 is not sending the correct summary routes. Which configuration must be applied to router R1 to summarize routes within Level 1?
R1(config-router)#no summary-address 1.0.0.0 255.0.0.0 level-1
R1(config-router)#summary-address 1.0.0.0 255.0.0.0 level-2
R1(config-router)#summary-address 1.0.0.0 255.0.0.0 level-1-2
R1(config-router)#summary-address 1.0.0.0 255.0.0.0 level-1

Refer to the exhibit. An engineer working for a private telecommunication company with an employee id: 1234:09:567 implemented this configuration on Router1, what is the effect of it?
Router 1 receives only one best path from neighbor 192.168.1.1
Router 1 sends only one best path to neighbor 192.168.1.1
Router 1 sends up to three paths to neighbor 192.168.1.1 for all routes
Router 1 sends and receives multiple best paths from neighbor 192.168.1.1

While configuring Cisco NSF awareness, a network engineer enters the bgp graceful-restart command after the BGP session is established in a router that runs IOS XE Software. Graceful restart capabilities are not exchanged. Which two actions should be taken? (Choose two.)
Reload the router
Verify that BGP route dampening is configured
Reduce BGP convergence time
Issue the clear ip bgp * command
Issue the show ip bgp neighbors command.

A network consultant is troubleshooting IS-IS instances to identify why a routing domains is having communication problems between the two instances. Which description of the possible cause of issues in the routing domain is true?
The same interface cannot be advertised in two different IS-IS instances
The IS-IS ISP and ISP2 instances are unrelated and unable to intercommunicate
The configured IS-IS NSEL value is not allowing the routing systems to establish a neighborship
The interface mode ip router is-is command was not included in the script
Routing Protocols
Refer to the exhibit. CE1 and CE2 cannot communicate through the service provider BGP peering is established between PE1 and PE2. IS-IS is the only routing protocol running in the service provider core. What step can be done to troubleshoot the issue?
Switch the IGPs running in the core from IS-IS to OSPF to support a Cisco MPLS TE tunnel from PE1 to PE2.
Configure BGP between CE and PE routers.
Confirm that IS-IS is running with metric-style narrow.
Verify the MPLS LSPs.

Refer to the exhibit. Router 1 has established an SR-TE tunnel with router 2. Which statement describes this configuration?
Router 1 has a list of labels used to explicitly lay out a path to router 2.
Router 1 and router 2 have a bidirectional tunnel set up with dynamic path selection.
Router 1 is the head-end tunnel and has dynamically chosen a path to router 2.
Router 2 is the head-end tunnel and has explicitly set a path to router 1.

Differences between OSPF and IS-IS: What are two?
Multiple Choice
What are two differences between OSPF and IS-IS? (Choose two.)
Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area
OSPF uses a router ID to identify a router, and IS-IS uses a system ID
OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol
Unlike OSPF, IS-IS supports virtual links
OSPF elects a DR and BDR, and IS-IS elects a DIS
