QUESTION: 5

Refer to the exhibit.

A network operator is getting the route for 10.11.11 0/24 from two upstream providers on
#XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?

weight of 0 on the prefix coming from 192.168.0.2
lower local preference on the prefix coming from 192.168.0.2
higher local preference on the prefix coming from 192.168.0.1
weight of 100 on the prefix coming from 192.168.0.1

Answer(s): A

Explanation:

Weight is the first attribute in path selection algorithm and is 0 for eBGP routes by default. If we set it to 0, router will continue from weight to the bottom, and when comparing neighbor router IDs it will find 192.168.0.1 less than 192.168.0.2 and st path will be selected as the best

Router 2 uses router 3 as the next hop for 192.168.0.0/24
Router 2 uses router 1 as the next hop for 192.168.0.0/24
Router 2 receives a Type 7 LSAs from router 3 for its connected subnets
