Implementing RSVP for MPLS-TE and MPLS O-UNI
Configuring Traffic Engineering Tunnel Bandwidth
To configure traffic engineering tunnel bandwidth, you must first set up TE tunnels and configure the reserved
bandwidth per interface (there is no need to configure bandwidth for the data channel or the control channel).
Cisco IOS XR software supports two MPLS DS-TE modes: Prestandard and IETF.
For prestandard DS-TE you do not need to configure bandwidth for the data channel or the control channel.
Note
There is no other specific RSVP configuration required for this application. When no RSVP bandwidth
is specified for a particular interface, you can specify zero bandwidth in the LSP setup if it is configured
under RSVP interface configuration mode or MPLS-TE configuration mode.

Confirming DiffServ-TE Bandwidth
Perform this task to confirm DiffServ-TE bandwidth.
In RSVP global and subpools, reservable bandwidths are configured per interface to accommodate TE tunnels
on the node. Available bandwidth from all configured bandwidth pools is advertised using IGP. RSVP signals
the TE tunnel with appropriate bandwidth pool requirements.
SUMMARY STEPS
