All 300-510 Test Inside Cisco Questions

Refer to the exhibit The engineering team noticed route disruptions when DSL subscriber 172.16.20.10 goes offline. In this service provider environment:

The OSPF backbone area is configured to advertise loopback prefixes

The PE routers are running BGP-IPv4 address family in a BGP-free core topology.

The DSL subscriber IP subnet 172.16.20.10/32 is redistributed in BGP on PE1

Which configuration on PE1 resolves the issue?

Refer to the exhibit. CE1 and CE2 use connectivity over the service provider cloud to reach CE3 In the event of a link failure in the service provider cloud which BGP feature relies on IGP convergence to quickly assist in the installation of a backup path?

Topology

Tasks

Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:

1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.

2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.

3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24, 172.16.101.0/24, and 172.16.103.0/24.

Refer to the exhibit.

Traffic flow from router R1 to router R6 is delay-sensitive It must consider potential link-failure and node-failure conditions Which configuration must an engineer apply to router R1 to route traffic to router R6 if router R2 fails?
