te bandwidth max-reservable-bandwidth dynamic

Function

The te bandwidth max-reservable-bandwidth dynamic command sets the proportion of the dynamic maximum reservable bandwidth to the physical bandwidth.

By default, the proportion of the dynamic maximum reservable bandwidth to the physical bandwidth is not set.

Usage Guidelines

Usage Scenario

The reservable bandwidth values set on the interfaces along a TE tunnel are used by the TE module to check whether a link meets all bandwidth requirements. If a fixed bandwidth value is set on an interface and the available physical bandwidth changes on the interface, the TE module cannot correctly evaluate link bandwidth resources if the available bandwidth is different than the configured reservable bandwidth.

To address this issue, you can set the dynamic maximum reservable bandwidth and BC dynamic reservable bandwidth. The maximum reservable bandwidth can be determined by setting the proportion of the maximum reservable bandwidth to the actual physical bandwidth. The BC dynamic reservable bandwidth can be determined by setting the proportion of the BC dynamic reservable bandwidth to the maximum reservable bandwidth. In this manner, the TE module can be aware of physical bandwidth changes on the interfaces along a tunnel.

To set the proportion of the dynamic maximum reservable bandwidth to the physical bandwidth of a specific interface, run the te bandwidth max-reservable-bandwidth dynamic command.

Configuration Impact

When both the te bandwidth max-reservable-bandwidth dynamic command and the te bandwidth max-reservable-bandwidth command are run in the same interface view, only the later executed command takes effect.

After the te bandwidth max-reservable-bandwidth dynamic command is run on an interface, only the te bandwidth dynamic command can be used to set the proportion of the BC dynamic reservable bandwidth to the maximum reservable bandwidth.

Precautions

MPLS TE-related commands apply only to MPLS TE and SR-MPLS TE. However, this command applies to SRv6 TE Policies, besides MPLS TE and SR-MPLS TE.

# Set the proportion of the maximum reservable bandwidth to the physical bandwidth to 80% on GE 0/1/0.
