In this lab, I learned the following:

  • configuring a HSRP group on physical interfaces,
  • testing how a PC can reach a remote subnet through a redundant gateway, by configuring its default gateway as the HSRP virtual address,
  • testing how the second router becomes Active,
  • testing interface tracking.

For interface tracking, at first, I thought there was a problem with the lab. Topology: sc1 configure interface tracking and a decrement value: sc2 When I shut down ser0/0 on R2, I expected R2 to become Standby router. But reality bites: sc3 Then I checked on R3. R3 is still Standby, not Active ! sc4 So what’s wrong? Here’s what Cisco says: How Object Tracking Affects the Priority of an HSRP Router
