Hi Scott,
Thanks for your answer. So this means I could also configure the physical interface in cisco frame-relay mode and than on the subinterface one frame-map with IETF mode while all the others are in cisco mode. This could lead to a nice, evil wording in a task...hehe regards Roger Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Scott Morris Gesendet: Samstag, 14.

You can check this using "show frame-relay map" once you have your mapping set! So while it won't hurt anything to put this on the sub-if or maping commands, it doesn't do anything different! The lab requirements may place a restriction of only using the "ietf" parameter once even though multiple DLCIs are affected. This is a good reason to watch what happens when using the physical interface's encapsulation command.

There is the task to configure the ser0/2/0 link between R2 and R5 with frame-relay RFC2427. Well, I configured the physical interface with frame-relay ietf. So I made a p-t-p subinterface and configured the frame-rel int dlci. Now, is it not necessary to also configure this interface dlci with ietf? ! interface Serial0/2/0 no ip address encapsulation frame-relay IETF no keepalive no frame-relay inverse-arp ! interface Serial0/2/0.2 point-to-point ip address 172.16.25.0 255.255.255.254 snmp trap link-status frame-relay de-group 1 25 frame-relay interface-dlci 25 IETF ! 2. A previous task requires us on R2 to mark everything above 512bytes with DE. The solution forgot to also apply this de-group to the Ser0/2/0 interface... regards Roger
