This attribute specifies 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 but 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. A value of 0 (the default) means that the bandwidth will be
the Peak Cell Rate for CLP0+1 as chosen by the user. A non zero
value overrides this reservation.
