High Availability (HA) is an integral component when designing and implementing switched networks. HA is technology delivered in Cisco IOS software that enables networkwide resilience to increase IP network availability. All network segments must be resilient to recover quickly enough for faults to be transparent to users and network applications. First Hop Redundancy Protocols (FHRPs) provide redundancy in switched LAN environments.
Today you will learn about the following:
- Hot Standby Router Protocol
- Virtual Router Redundancy Protocol
- Gateway Load Balancing Protocol
This lesson maps to the following ICND2 syllabus requirements:
ü Recognise High Availability (FHRP)
- HSRP
- VRRP
- GLBP
