This attribute gives the bandwidth (in bits per second) reserved by a
path on each of the trunks of its route.This attribute represents the
bandwidth for traffic outgoing to 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.
