Sim 06: HSRPv2 with Object Tracking

Blueprint 3.3.c, 1.1 · Difficulty: Medium · Time target: 15 minutes

DIST1 and DIST2 are Layer 3 distribution switches for VLANs 10 and 20. Someone configured a basic HSRP group on VLAN 10 with all defaults. Replace it with a proper design: HSRP version 2, one active switch per VLAN, authentication, fast timers, and failover when an uplink goes down.
