Explicit Path Configuration

One other command set is used in MPLS TE, but it doesn't fit into any of the preceding categories all that well.

Command Modifiers Use
ip explicit-path {identifier identifier | name name} [disable | enable] Configures an explicit path.

This puts you into a submode called cfg-ip-expl-path, where your configuration choices are as follows.

Command Modifiers Use
append-after {previous-index {exclude-address ip-addr | next-address [loose | strict] ip-addr}} Adds a path-option statement after an existing path-option statement.
exclude-address {ip-addr} An address (router ID or interface address) to avoid while doing CSPF for this path option.
index {index {exclude-address ip-addr | next-address [loose | strict] ip-addr}} Much like the append-after command, except that index overwrites whatever is already configured at a given level in the path option.
list None Unusual for configuration mode, this command doesn't configure any-thing. Instead, it lists the addresses you already have configured in the path option, and their indices.
next-address {[loose | strict] ip-addr} Gives the next address in the path you'd like to take. exclude-address and next-address are mutually exclusive. If you use them both in the same explicit path, the path is not successfully calculated.
no {index index} Removes a given index number.

For more documentation on and examples of this command, see Chapter 4.
