A large enterprise uses a full mesh of IBGP sessions between 50 routers. The network team wants to reduce the number of BGP sessions and improve scalability. They decide to implement route reflectors. Which configuration is required on the route reflector to allow it to reflect routes to its clients?

Set the next-hop-self on the route reflector

Configure the neighbor as a route-reflector-client

Create a confederation with sub-AS numbers

Enable BGP soft-reconfiguration inbound

A network administrator changes an inbound route-map on a BGP neighbor to filter a specific prefix. The administrator wants to apply the new policy without disrupting the BGP session. Which action should be taken?

Use the clear ip bgp neighbor hard command

Use the clear ip bgp neighbor soft in command

Shut down the BGP neighbor and re-enable it

An enterprise has two BGP peers providing the same route. The administrator wants to prefer the route from peer A over peer B. Both peers are in the same AS. The administrator decides to use a route-map to set local preference on routes from peer A. Which configuration is correct?

Apply a route-map that prepends AS path on peer A's outbound updates

Apply a route-map that sets local preference 200 to peer A's inbound updates

Apply a route-map that sets weight 100 to peer A's outbound updates

Apply a route-map that sets MED 100 to peer A's outbound updates

A network engineer is configuring a new IBGP session between two routers in the same AS. The routers are not directly connected, and the engineer wants to use loopback interfaces for the session. Which configuration is required on both routers to establish the session?

Set the next-hop-self on the neighbor

Configure the neighbor as a route-reflector-client

Use the update-source loopback0 command and ensure the neighbor is reachable via IGP

Use the ebgp-multihop command on the neighbor

A company advertises its prefix to two ISPs. The primary ISP is preferred for inbound traffic. The backup ISP is currently receiving the same prefix with an equal AS path length. The administrator wants to make the backup path less preferred without affecting the primary. Which configuration should be applied on the backup ISP advertisement?

Set a higher local preference on the backup advertisement

Prepend the company's AS number three times on the backup advertisement

Set a lower MED on the backup advertisement

Use a community to tag the backup route
