To configure an explicit path, you must first create the path and then configure the use of any one path. If an explicit path is not configured, the minimum cost path is used by default. If an explicit path is configured and is functioning, the specified path is used. To create an explicit path for the scenario in Figure 51-14, follow these steps: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Step 7 Command Purpose switchS# config t Enters configuration mode. switchS(config)# fc-tunnel explicit-path Path1 Places you at the explicit path prompt for the switch(config-explicit-path)# path named Path 1. switchS(config-explicit-path)# next-address 10.10.10.2 strict switchS(config-explicit-path)# next-address 10.10.10.3 strict switchS(config-explicit-path)# next-address 10.10.10.4 strict Specifies that the next hop VSAN interface IPv4 addresses and the previous hops specified in the explicit path do not require direct connection. switchS(config)# fc-tunnel explicit-path Path2 Places you at the explicit path prompt for switch(config-explicit-path)# Path2. switchS(config-explicit-path)# next-address 10.10.10.5 strict switchS(config-explicit-path)# next-address 10.10.10.4 strict Specifies that the next hop VSAN interface IPv4 addresses and the previous hops specified in the explicit path do not require direct connection. switchS(config)# fc-tunnel explicit-path Path3 Places you at the explicit path prompt for switch(config-explicit-path)# Path3. switchS(config-explicit-path)# next-address 10.10.10.3 loose Configures a minimum cost path in which the 10.10.10.3 IPv4 address exists. Note In Figure 51-14, Path 3 is the same as Path 1-10.10.10.3 exists in Path 1. Using the loose option, you can achieve the same effect with one command instead of issuing three commands (using the strict option) in Step 3.
