If the 'localAvailable' bit is set, it indicates that the link downstream of this node has been protected by means of a local repair mechanism. This mechanism can be either the one-to-one backup method or the facility backup method. If the 'localInUse' bit is set, then it indicates that the local protection mechanism is being used to maintain this tunnel. If the 'bandwidthProtected' bit is set, then it indicates that the backup path is guaranteed to provide the desired bandwidth. If the 'nodeProtected' bit is set, then it indicates that the backup path provides protection against the failure of the next LSR along the LSP.
