Plug the cable to the 2621A router back in and notice that the 2621A
router does not become the active router. Run debug stand on the
2501A router to see this.

Even though the 2621A router has sent and received a hello, it is in
speak state and did not cause a reelection because the priorities are the
same. You want the 2621A to be the active router because it is running
FastEthernet, so change the priority of the router so it's higher and
make it force an election. In addition, to make an HSRP router force
an election, you must also add the preempt command or it won't
work.
