Section 4.6 says:
Available Bandwidth: This field carries the available bandwidth on a link, forwarding adjacency, or bundled link in IEEE floating-point format with units of bytes per second. For a link or forwarding adjacency, available bandwidth is defined to be residual bandwidth (see Section 4.5) minus the measured bandwidth used for the actual forwarding of non-RSVP-TE label switched path packets. For a bundled link, available bandwidth is defined to be the sum of the component link available bandwidths minus the measured bandwidth used for the actual forwarding of non-RSVP-TE label switched path packets. For a bundled link, available bandwidth is defined to be the sum of the component link available bandwidths.
It should say:
Available Bandwidth: This field carries the available bandwidth on a link, forwarding adjacency, or bundled link in IEEE floating-point format with units of bytes per second. For a link or forwarding adjacency, available bandwidth is defined to be residual bandwidth (see Section 4.5) minus the measured bandwidth used for the actual forwarding of non-RSVP-TE label switched path packets. For a bundled link, available bandwidth is defined to be the sum of the component link (residual) bandwidths minus the measured bandwidth used for the actual forwarding of non-RSVP-TE label switched path packets.For a bundled link, available bandwidth is defined to be the sum of the component link available bandwidths.
Notes:
Two sentences to explain 'available bandwidth' on a bundled link, but one says "sum of component available bandwidth minus xxx", the other says "sum of component available bandwidth", is conflicting. need to change the first sentence to 'sum of component residual bandwidth minus xxx'
