Configuring the Amount of Bandwidth Subscribed for Bypass LSPs

You can configure the amount of bandwidth subscribed to bypass LSPs. You can configure the bandwidth subscription for the whole bypass LSP or for each class type that might traverse the bypass LSP. You can configure any value between 1 percent and 65,535 percent. By configuring a value less than 100 percent, you are undersubscribing the bypass LSPs. By configuring a value greater than 100 percent, you are oversubscribing the bypass LSPs.

The ability to oversubscribe the bandwidth for the bypass LSPs makes it possible to more efficiently use network resources. You can configure the bandwidth for the bypass LSPs based on the average network load as opposed to the peak load.

To configure the amount of bandwidth subscribed for bypass LSPs, include the subscription statement:




subscription percentage {
ct0 percentage;
ct1 percentage;
ct2 percentage;
ct3 percentage;
}

You can include this statement at the following hierarchy levels:

[edit protocols rsvp interface interface-name link-protection]
[edit logical-systems logical-system-name protocols rsvp interface interface-name link-protection]
