Refer to the exhibit. An engineer is troubleshooting an issue with this network and notices that prefixes from R3 are missing on the R1 routing table Due to repeated ASN when the 10 0 0 0'8 prefix from R3 arrives at R1, BGP automatically rejects it There is no prefix-list on R1 which blocks the traffic from R3 What should the engineer do to fix the problem so that BGP allows that prefix on R1?

出題：3

Refer to the exhibit.

A network operator is working to filter routes from being advertised that are covered under an aggregate announcement.

Which configuration change ensures that only the aggregate is announced now and in the future if other networks are to be added?

A. Configure the summary-only keyword on the aggregate command

B. Set each specific route in the AGGRO policy to drop instead of suppress-route

C. Filter the routes on the receiving router

D. Set each specific route in the AGGRO policy to remove instead of suppress-route
