CCNP - ENTERPRISE - First Hop Redundancy notes

- A standby router configured with HSRP will take 9 seconds to detect the loss of an active router (based on default timers)
- With GLBP there is no limit to the number of routers you can implement in a group, however only a maximum of 4 active routers will be forwarding at any given time (due to a limit of 4 virtual MAC addresses that can be used with a group).
- Default GLBP priority is 100, when a router is the Active Virtual Gateway or an Active Virtual forwarder either the priority has been increased from the default on the AVG OR the Priority has been reduced from the default on the AVF
