Chapter 19 FCIP Configuration
FCIP High Availability
The following characteristics set FSPF solutions apart from other solutions:
•Each FCIP link is a separate (E)ISL.
•The FCIP links can connect to different switches across two SAN islands.
•The Fibre Channel traffic is load balanced across the FCIP link.
VRRP
Figure 19-14 displays a 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 19-14 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 19-15 displays an Ethernet PortChannel-based high availability FCIP example. This solution
addresses the problem caused by individual Gigabit Ethernet link failures.
