Well, if you are allowed to use sub-interfaces do it, then you do not have
to worry about mapping. If you cannot use sub-interfaces you have to provide
layer 2 to 3 mapping. In new style pvc it is done with "protocol ip 1.1.1.1
broadcast" in pvc mode. I do not think you can do minimum bandwidth with UBR
try ubr+ to set men and max bandwidth. Also you can do it using vc-class and
ubr+. You are correct in saying that you do not need map-groups / map-list,
but you still need mapping.

                Thanks. Someone else just pointed that out as well. I don't
know why I did
                not see that last time I was on an ATM interface, I must
have just been in a
                rush. So it sounds like if I need to specified a minimum and
a maximum for
                UBR, then I need to use the PVC 0/100 method instead of a
map group and
                map-list, is that correct?

                When you configure PVC, let's say you type pvc 0/100 and hit
enter you will
                be in pvc mode. Type ? to see all the available options.

                mdrtgate01(config)#int atm1/0.777 po
                mdrtgate01(config)#int atm1/0.777 point-to-point
                mdrtgate01(config-subif)#pvc 0/100
                mdrtgate01(config-if-atm-vc)#en
                mdrtgate01(config-if-atm-vc)#encapsulation aal
                mdrtgate01(config-if-atm-vc)#encapsulation aal5sn
                mdrtgate01(config-if-atm-vc)#encapsulation aal5snap
                mdrtgate01(config-if-atm-vc)#

                                Yan,

                                I didn't see any option for aal5snap under
the pvc 0/1
                method. Maybe I just
                                missed it.I'll try again the next chance I
get.

                                Thanks for the response.

                                Jeff

                                When configure new style PVC.
                                Int atm 2/0
                                Pvc 0/1 then hit enter and it will get you
into pvc mode
                where you can
                                specify encapsulation, QoS, and lots more.

ATM PVCs with
                UBR vs. ABR

                                                When configuring ATM PVCs
similar to the
                example in
                                Caslow's/Pavlichenko's
                                                book,

                                                Interface ATM 3/0
                                                ATM PVC 1 0 99 aal5snap
                                                IP address 1.1.1.1
255.255.255.0
                                                Map-group mygroup
                                                Map-list mygroup
                                                 Ip address 2.2.2.2 atm-vc 1
aal5snap

                                                I cannot find an option for
UBR, only ABR.
                After looking
                                through the
                                                archives I see that the
above is an older
                form of mapping a
                                PVC. However, I
                                                cannot find an aal5snap
option when using
                the newer method,

                                                Interface ATM 3/0
                                                IP address 1.1.1.1
255.255.255.0
                                                Pvc-mypvc 0/1......

                                                Is there a way of specifying
UBR for the
                first example and
                                if not, is there
                                                an option for aal5snap for
the second
                method?
                                                Also, any helpful links
would be greatly
                appreciated.

                                                Thanks,

                                                Jeff
