Configuring Reporting of Automatic Bandwidth Allocation Statistics for LSPs

Copyright © 2017, Juniper Networks, Inc.
Automatic bandwidth allocation allows an MPLS tunnel to automatically adjust its
bandwidth allocation based on the volume of traffic flowing through the tunnel. You can
configure the device to collect statistics related to automatic bandwidth allocation by
completing the following steps:
To collect statistics related to automatic bandwidth allocation, configure the
1.
auto-bandwidth option for the
hierarchy level. These settings apply to all LSPs configured on the router on which
you have also configured the

NOTE: To prevent unnecessary resignaling of LSPs, it is best to configure
an LSP adjustment interval that is at least three times longer than the
MPLS automatic bandwidth statistics interval. For example, if you
configure a value of 30 seconds for the MPLS automatic bandwidth
statistics interval (
hierarchy level), you should configure a value of at least 90 seconds for
the LSP adjustment interval (
