VRRP-E Extension for Server Virtualization

VRRP-E is enhanced with the VRRP-E extension for Server Virtualization feature so that the Brocade
device attempts to bypass the VRRP-E master router and directly forward packets to their
destination through interfaces on the Backup router.

Figure 42

shows an example of VRRP-E Extension for Server Virtualization. As shown, the virtual

servers are dynamically moved between Host Server 1 and Host Server 2. Each time the virtual
server is activated, it can be on a different Host Server, and sometimes the traffic crosses the WAN
two times before it reaches the client. For example, in the VRRP-E implementation (without VRRP-E
Extension for Server Virtualization), traffic from virtual server 1 to the client at 10.0.0.X was
switched to the VRRP-E master router, then routed back to VRRP-E Backup router, and then routed
to the client (the normal forwarding path, dotted lines).
