Configuring the Path Bandwidth

Each LSP has a bandwidth value. This value is included in the sender’s Tspec field in RSVP path setup messages. To specify a bandwidth value, include the bandwidth statement:




bandwidth bps;

For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.

You specify the bandwidth value in bits per second, with a higher value implying a greater user traffic volume. The default bandwidth is 0 bits per second.

A nonzero bandwidth requires transit routers to reserve capacity along the outbound links for the path. RSVP’s reservation scheme is used to reserve this capacity. Any failure in bandwidth reservation (such as failures at RSVP policy control or admission control) might cause the LSP setup to fail.
