The explicit path must be created in the source switch. 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

Path 2 (minimum cost)
Figure 52-14, follow these steps:
Purpose
Enters configuration mode.
Places you at the explicit path prompt for the
path named Path 1.
Specifies that the next hop VSAN interface
IPv4 addresses and the previous hops specified
in the explicit path do not require direct
connection.
Places you at the explicit path prompt for
Path2.
Specifies that the next hop VSAN interface
IPv4 addresses and the previous hops specified
in the explicit path do not require direct
connection.
Places you at the explicit path prompt for
Path3.
Configures a minimum cost path in which the
10.10.10.3 IPv4 address exists.
In Figure
Note
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.
