FSPF routing rules and traffic isolation

All traffic must use the lowest cost path. FSPF routing rules take precedence over the TI zones, as
described in the following situations.
272
Ensure that there are multiple paths between switches.
Disabling failover locks the specified route so that only TI zone traffic can use it. Non-TI zone
traffic is excluded from using the dedicated path.
You should enable failover-enabled TI zones before enabling failover-disabled TI zones, to avoid
dropped frames.
When you issue the cfgEnable command to enable the zone configuration, if you have failover
disabled zones, do the following:
1. Temporarily change failover-disabled TI zones to failover-enabled.
2. Enable the zones (cfgEnable).
3. Reset all the zones you changed in
4. Enable the zones again (cfgEnable).
These steps are listed in the procedures in this section.
It is recommended that TI zone definitions and regular zone definitions match.
Domain controller frames can use any path between switches. Disabling failover does not
affect Domain Controller connectivity.
For example, in Figure 32, if failover is disabled, Domain 2 can continue to send domain
controller frames to Domain 3 and 4, even though the path between Domain 1 and Domain 3
is a dedicated path. Domain controller frames include zone updates and name server queries.

It is recommended that the insistent Domain ID feature be enabled; if a switch changes its
active domain ID, the route is broken. See the configure command in the Fabric OS Command
Reference for information about setting insistent Domain ID.
