262 Using the FC-FC routing service
.
Figure 16 Configuration during the upgrade
The switch Domain ID and BB fabric ID of the new FC router can be identical. Once the metaSAN is stable,
EX_Ports on the new router are ‘active’, the old router can be taken out of the setup.
Redundant configuration
The configuration shown in Figure 17 on page 261, shows that old routers can be removed one by one. For
example, FC router 2 can be replaced with the new FC router. You are expected to maintain the
connections to the edge fabrics and the other router, same as with old router. Configuration parameters
described in ”To configure the new router:” on page 262 should also be preconfigured on the new routers
and match with the routers being replaced. The same procedure can be repeated for FC router 1.
NOTE: During the swap, traffic flowing through the ISL is affected.
Figure 17 shows an example of a simple redundant configuration.

Dual backbone configuration
In the configuration shown in Figure 18, follow the steps described in ”To configure the new router:” on
page 262 for each FC router.
Following is the example of a dual backbone configuration.
