Configuring Guaranteed Bandwidth Service
To configure guaranteed bandwidth service, perform the following required configuration tasks:
•
•
•
For guaranteed bandwidth service configuration examples, see the MPLS Traffic Engineering—DiffServ
Aware, Release 12.2(14)S feature module.
Providing Strict QoS Guarantees Using DS-TE Sub-pool Tunnels
To provide strict QoS guarantees using DS-TE sub-pool tunnels, do the following:
1.
OL-7433-09
configures DS-TE on the tunnel interface.

Providing Strict Guarantees and Differentiated Service in the Same Network, page 20-26
Select a queue (referred to as per-hop behavior (PHB) in DiffServ terminology) to be used
exclusively by the strict guarantee traffic. This queue is referred to as the guaranteed bandwidth
queue.
If you want to provide delay or jitter guarantees, use the DiffServ expedited forwarding queue (EF
PHB). On the Cisco 10000 series router, it is the absolute priority queue.
Purpose
Configures the path (hops) that you want an MPLS traffic
engineering tunnel to use. You can configure many path options
for a single tunnel, including both dynamic and explicit path
options.
(Optional) protect indicates a backup label-switched path (LSP).
When you configure several path options, use lower numbered
options for number.
dynamic indicates that the router dynamically calculates the LSP
path.
explicit indicates that the LSP path is an IP explicit path.
name path-name specifies the path name of the IP explicit path.
This path name represents the specific IP addresses of the hops.
path-number is the path number of the IP explicit path.
lockdown indicates that the LSP cannot be reoptimized.
