The first two highlighted portions of the output illustrate where the MPC recognized what is called interesting traffic. Interesting traffic targets a host in another ELAN. Therefore, the source and destination Layer 3 addresses differ. But the destination MAC address targets a neighbor ingress MPS. Why does it see a MAC address for the MPS? The MPC sees a MAC address for the MPS because this is the first router in the default path. The MPC puts the first hop router's MAC address in the data link header. The two highlighted statements are for frames 9 and 10 within the configured one-second period (the first eight frames were removed for simplicity). There is no indication of the frame count, so you might need to sort through the debug output to see if at least ten frames were seen. Because there are ten frames per second, the MPC triggers a resolution request to the ingress MPS. This is shown in the third highlighted area of Example 10-18.

Eventually, the MPC should receive a resolution reply from the MPS as shown in Example 10-19.
