Example 46 Using the show ip explicitpaths name Command

RtrA#show ip explicit-paths name foo

PATH foo (strict source route, path complete, generation 28) 1: next-address 192.168.1.2 2: next-address 192.168.7.4 3: next-address 192.168.1.5

As you can see, path option foo is a strict source route, it is a complete path (paths are almost always complete; incomplete paths are rare), and it is generation 28 of that path option. The generation number changes every time the path option is changed—in much the same way that the BGP table version changes when any updates happen.

If the explicit path in Example 4-6 had any loose subobjects specified in it (see "Interarea Tunnels" later in this chapter), you'd see loose source route rather than strict source route in the output of show ip explicit-paths.

This example uses the RID for RtrB and RtrE, but uses RtrD's incoming link address on link 2 to specify which link the tunnel crossed. The explicit path configuration can accept a mix of node addresses and link addresses; it's pretty flexible that way. Example 4-7 demonstrates another way to specify the explicit path.
