Reserving Bandwidth for MPLS
In order to manage the bandwidth used by MPLS RSVP-TE LSPs, a configured amount of bandwidth must be reserved for MPLS. Bandwidth in the transmit direction must be reserved on all MPLS interfaces which will be used as egress interfaces for RSVP-TE LSPs requesting bandwidth. Bandwidth in the receive direction can be optionally reserved on all MPLS interfaces that will be used as ingress interfaces for RSVP-TE LSPs requesting bandwidth. Note that the receive bandwidth reservation can be exceeded, and is provided only for tracking and informational purposes.
The committed_rate_unit must be specified in Kbps, Mbps, or Gbps. Choosing the vlan all option reserves the specified amount of bandwidth on all MPLS interfaces.
The default reserved value is zero. Therefore, no LSPs requesting bandwidth can be established until the bandwidth has been configured.
