Câu 160: 300-410: Implementing Cisco Enterprise Advanced Routing and Services (ENARSI)

Refer to the exhibit. BGP and EIGRP are mutually redistributed on R3, and EIGRP and OSPF are mutually redistributed on R1. Users report packet loss and interruption of service to applications hosted on the 10.1.1.0/24 prefix. An engineer tested the link from R3 to R4 with no packet loss present but has noticed frequent routing changes onR3 when running the debug ip route command. Which action stabilizes the service?

1. A. Reduce frequent OSPF SPF calculations on R3 that cause a high CPU and packet loss on traffic traversing R3.
2. B. Tag the 10.1.1.0/24 prefix and deny the prefix from being redistributed into OSPF on R1. — đáp án hiện tại
3. C. Place an OSPF distribute-list outbound on R3 to block the 10.1.1.0/24 prefix from being advertised back to R3.
4. D. Repeat the test from R4 using ICMP ping on the local 10.1.1.0/24 prefix, and fix any Layer 2 errors on the host or switch side of the subnet.
