This attribute gives the bandwidth (in bits per second) reserved by a
path on each of trunks of its route. This attribute represents the
bandwidth for traffic incoming from the remote end point. This
value should be chosen to achieve the amount of statistical
bandwidth sharing that is desired by the network administration.
This reservation is not enforced and is used to determine how many
paths can be supported on a trunk. Both ends should be provisioned
with the correct values allowing for the fact that transmit at this end
represents receive at the remote end. Note that when the values do
not correspond, the originating end of the connection determines the
value.
