Routing Policy and Manipulation

Question Image

Refer to the exhibit. Company_A hosts multiple online VoD platforms. R3 connects to the MAN with a 100 Mbps link. R2 has only a 10 Mbps connection, but it has the lowest hop count to R1. A network engineer must allow users in area 49.421 e.2331.5548.7624.00 to access online library resources by using the best possible route toward the online platforms to guarantee the highest connection quality. After the engineer implements the requirements, they observe an excessive number of routes in the R4 routing table and high memory consumption on the router. Which two actions must the engineer take to resolve the issue?

Choose two
Explanation

Redistributing Level 2 routes into Level 1 at R3 makes the MAN-hosted platform prefixes reachable from the Level 1 area through R3 and its higher-bandwidth 100 Mbps connection. Summarizing 64.45.52.0/22 into Level 1 at R3 advertises a single aggregate instead of the individual platform routes, reducing routing-table and memory consumption on Level 1 routers. Cisco documents summary-address address mask level-1 as the form that summarizes routes redistributed into Level 1 IS-IS.
