1:

If a RIF is present in a source-routed frame, does a source-route switch ever examine the MAC address of a frame?

2:

To how many VLANs can a TrBRF belong?

3:

The transparent-bridge learning process adds entries to the bridging table based on the source address. Source addresses are never multicast addresses. Yet when examining the Catalyst bridge table, it is possible to see multicast. Why?

4:

Two Cisco routers attach to a Catalyst. On one router you type show cdp neighbor.You expect to see the other router listed because CDP announces on a multicast address 01-00-0C-CC-CC-CC, which is flooded by bridges. But you see only the Catalyst as a neighbor. Suspecting that the other router isn't generating cdp announcements, you enter show cdp neighbor on the Catalyst. You see both routers listed verifying that both routers are generating announcements. Why didn't you see the second router from the first router? (Hint: neither router can see the other.)
