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 on
R3 when running the debug ip route command.
Which action stabilizes the service?
The issue is due to the mutual redistribution of routes between BGP, EIGRP, and OSPF, which can cause routing loops and instability. Specifically, the 10.1.1.0/24 prefix needs to be carefully managed to avoid it being advertised back into OSPF on R1 after being redistributed through EIGRP and BGP. By tagging the 10.1.1.0/24 prefix and denying its redistribution into OSPF on R1, you can prevent routing updates from causing frequent changes and potential loops, thereby stabilizing the routing environment and service.
Given answer is correct. B is the only one with makes sence. A = this is not an action C = Outbound to fix advertisments back into R3? Inbound would be good but this doesn't fix the problem D = No L2 issue The Issue is that the AD from IBGP is 200. Highter than the AD from OSPF (110) or external EIGRP (170)
The correct answer is: B
Choose B. Because C apply on R3 out which is not correct
B is correct
