Trouble Ticket 18-3

Problem: You are the administrator for BGP autonomous system 65502. Traffic reports indicate that all traffic out of the autonomous system is flowing through R3 and across the backup link. This is undesirable unless the link between R2 and R1 fails.

To verify the issue, you use traceroute from R5. As shown in Example 18-76, the trace to 10.1.1.1 and 10.1.1.65 goes through R3 to get to autonomous system 65501.
