Configuring MPLS
Statistics for Automatic Bandwidth Allocation
To enable automatic bandwidth allocation, you first
need to configure MPLS statistics. Include the auto-bandwidth option for the statistics statement. You can also use the interval option to specify the interval for calculating the
average bandwidth usage.
These settings apply to all LSPs configured on
the router on which you have also configured the auto-bandwidth statement at the [edit protocols mpls label-switched-path label-switched-path-name] hierarchy level. You can
also set the adjustment interval on specific LSPs.
 |
Note:
To prevent unnecessary resignaling of LSPs, it is best to configure
an MPLS automatic bandwidth statistics interval of no more than one
third the corresponding LSP adjustment interval. For example, if you
configure a value of 30 seconds for the interval statement at the [edit protocols mpls statistics] hierarchy
level, you should configure a value of no more than 90 seconds
for the adjust-interval statement at the [edit protocols
mpls label-switched-path label-switched-path-name auto-bandwidth] hierarchy level. See also Configuring the
Automatic Bandwidth Allocation Interval.

To configure the MPLS and automatic bandwidth allocation
statistics, include the statistics statement:
-
statistics {
- auto-bandwidth;
- file filename <files number> <no-stamp> <replace> <size size> <world-readable | no-world-readable>;
- interval seconds;
- }
You can include this statement at the following
hierarchy levels:
-
[edit protocols mpls]
-
[edit logical-systems logical-system-name protocols mpls]
