Assume you have the following hypothetical scenario, R2 and R7 on one site, connected to a WAN infrastructure via multiple links (omitted here), where there are two gateways R5 & R6:
Client requests the following:
- R2 should be the active HRSP router if R2 has connectivity to BOTH R5 and R6 loopbacks.
- R7 should be the active HSRP router if R2 has connectivity to only ONE of the 2 gateways.
- R2 should be the active HSRP router if R2 has NO connectivity to either R5 or R6.
