Hi Yakov,

Could you clarify your point for this errata?  In RFC 4090, in the
terminology it says:
" Backup Path: The LSP that is responsible for backing up one
                       protected LSP.  A backup path refers to either a
detour LSP
                       or a backup tunnel.

  Backup Tunnel: The LSP that is used to backup up one of the many
                 LSPs in many-to-one backup."

Thanks,
Alia
