Redundant configuration Figure 89 shows an example of a simple redundant configuration. The configuration shown in Figure 89, 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 545 should also be preconfigured on the new routers and match with the routers being replaced. The backbone fabric ID of the new FC router should be the same as that of the replaced router. The same procedure can be repeated for FC router 1. NOTE: During the swap, traffic flowing through the ISL is affected. Figure 89 shows an example of a simple redundant configuration. Figure 89 Redundant router configuration Dual backbone configuration In the configuration shown in Figure 90, follow the steps described in "To configure the new router:" on page 545 for each FC router. Figure 90 is an example of a dual backbone configuration. Figure 90 Dual backbone fabric configuration 544 Migrating from an MP Router to a 400 MP Router
