Description: When vRtrMplsLspPathBwProtect has a value of 'true', bandwidth protection is enabled on a LSP. LSPs that reserve bandwidth will be used for EF services where customers need guaranteed bandwidth. It is expected that multiple EF services will be assigned to a single LSP. When bandwidth protection is enabled on an LSP, each time this LSP is used for a certain service the bandwidth allocated on that service is deducted from the bandwidth reserved for the LSP. Once the bandwidth is exhausted on the LSP, the ESR will provide feedback to the provider indicating that this LSP has exhausted its resources.
