Traffic engineering rates define the bandwidth parameters for the dynamic bypass LSP to be created corresponding to a protected link. The dynamic bypass LSP bandwidth is based on this command's mean-rate and protected LSP backup path requested bandwidth.
When there is no configuration for the interface mode mean-rate value, then all dynamic bypass LSPs create with the bandwidth the same as the backup path requested bandwidth. This means that system tries to create a dynamic bypass LSP with backup path requested bandwidth and dynamic bypass LSP bandwidths varying from one to the other, based on the riding backup.
When the interface mode configured mean-rate value is 0 kbps, such as when it is explicitly configured as 0 by use, then the system can create dynamic bypasses for backup bandwidth requests of 0 kbps only. When the backup path bandwidth is more than zero, then such a request does not lead to the creation of a new dynamic bypass LSP. This option provides a way for the user to limit the dynamic bypass creations to only non-bandwidth protected backups.
When the interface mode configuration mean-rate value is a non-zero value, then the system does not create dynamic bypasses for the backups which request backup bandwidth that is more than the interface mode configured value. When the backup bandwidth is less than, or equal to, the configured value, then such request can be honored to ride an existing dynamic bypass or create a new dynamic bypass. With this configuration, all the newly created dynamic bypasses have a fixed bandwidth (value same as interface mode user configured non-zero mean-rate value).
A mean-rate value more than current interface reservable bandwidth is not recommended. Configuration succeeds with the new value even when it is more than the interface reservable bandwidth.
