GLBP_election.cap (8.4 KB)
Routers 1, 2, and 3 participate in a GLBP election. R1 becomes the AVG due to having the highest priority (200), and R3 becomes the standby GLBP. All three routers become AVFs. VRRP_preempt.cap (1.2 KB)
Initially R3 is the master, R2 is backup, and R1 is offline. R1 comes back online with a priority of 200, preempting R3 to become the master router.
VRRP_failover.cap (2.4 KB)
The master router (R1) goes offline. After the down interval passes (roughly 3 seconds), R3 takes over as the master router in packet #12. R2 also offers to take over but R3 wins because it has the higher IP address.
HSRP_coup.cap (3.9 KB)
Initially only routers 3 (active) and 2 (standby) are online. R1 comes online with a priority higher than R3's. R1 takes over as the active router (the coup occurs in packet #22) almost immediately. R2 is bumped down to passive and R3 becomes the standby router.
HSRP_failover.cap (3.0 KB)
R1 is the active router, R3 is the standby, and R2 is passive. R1 goes offline and R3 takes over as active after ten seconds. R2 is then promoted to the standby state.
HSRP_election.cap (3.7 KB)
The Ethernet link shared by routers 1, 2, and 3 comes online. R1 wins the HSRP election because it has a priority of 200 (versus the default of 100 held by the other two routers). R3 becomes the standby router.
