FHRP

The video demonstrates IPv6 HSRP configuration on Cisco router. We will show how HSRP is integrated with IPv6 Router Advertisement message to provide first hop redundancy to end-hosts. HSRPv6 will be operationally compared to the IPv6 Default Router Preference method and any distinctions between the two will be made. We will use a router and Windows 7 computer as our test end devices.

The video demonstrates GLBP configuration on two routers providing an IP gateway. We review the roles of Active Virtual Gateway (AVG) and Active Virtual Forwarder (AVF), and how load balancing is achieved, and perform various failover test scenarios. GLBP main distinction from HSRP and VRRP is its ability to natively provide gateway load balancing to end devices, hence increase in protocol complexity.

The video demonstrates VRRP configuration on two routers providing an IP gateway. Failover behavior caused by interface object tracking is observed. We also review VRRP packet captured on Wireshark. VRRP serves the same purpose as HSRP with minor differences: one being a standard protocol, hence it would be a protocol of choice for inter-operability with other vendors.

The video demonstrates HSRPv2 configuration on two routers providing an IP gateway. Failover behavior caused by interface object tracking is observed. We look into the HSRP packet and identify differences between having MD5 authentication enabled and disabled. HSRP provides redundancy at the first-hop gateway to end devices. Although load balancing is possible, multiple HSRP group and virtual IPs are needed.
