ISDN BRI Interface Bandwidth

What is the recommended bandwidth value for an ISDN BRI interface? Should it be left at the default of "64" for the purposes of the "dialer load-threshold" command calculations or should it be adjusted to "128" to reflect the two "B" channels that are available?

Re: ISDN BRI Interface Bandwidth

The bandwidth command is used for routing decisions....changing the bandwidth on the BRI (the D channel) will not change the BW under the B1 & B2 channels which defaults to 64k....the dialer load threshold is based off the load on these bearer channels (B1, B2).
