About FCIP
VRRP
Figure 48-6 displays a Virtual Router Redundancy Protocol (VRRP)-based high availability FCIP
configuration example. This configuration requires at least two physical Gigabit Ethernet ports
connected to the Ethernet switch on the island where you need to implement high availability using
VRRP.
Figure 48-6 VRRP-Based High Availability
The following characteristics set VRRP solutions apart from other solutions:
• If the active VRRP port fails, the standby VRRP port takes over the VRRP IP address.
• When the VRRP switchover happens, the FCIP link automatically disconnects and reconnects.
• This configuration has only one FCIP (E)ISL link.
Ethernet PortChannels
Figure 48-7 displays an Ethernet PortChannel-based high- availability FCIP example. This solution
addresses the problem caused by individual Gigabit Ethernet link failures.
Figure 48-7 Ethernet PortChannel-Based High Availability
The following characteristics set Ethernet PortChannel solutions apart from other solutions:
• The Gigabit Ethernet link level redundancy ensures a transparent failover if one of the Gigabit
Ethernet links fails.
• Two Gigabit Ethernet ports in one Ethernet PortChannel appear like one logical Gigabit Ethernet
link.
