RSVP-TE - Multiple Bypass LSP for Node/Link Protection

By default, link protection relies on a single bypass label-switched path (LSP) to provide path protection for an interface. However, you can also specify multiple bypass LSPs to provide link protection for an interface. You can individually configure each of these bypass LSPs or create a single configuration for all the bypass LSPs. If you do not configure the bypass LSPs individually, all the LSPs share the same path and bandwidth constraints. You can use multiple link protection bypass LSPs when link protection, or node-link protection, is configured.
