I have forwarded your question on, because I don't have the configs/final workbook with me at the moment, so please forgive the vague answers... 1. You can assign IETF as part of the "encap frame-relay" command, making it the default. Or you can assign it on the frame-relay map, or frame-relay interface-dlci command. When you do "show frame pvc", you should see the appropriate encapsulation. 2. If you are doing map classes, it's common to use the interface-dlci command to do this. If you want the same parameters on ALL dlci's, you can do this as an interface command as well. The effect would be the same, so it's just personal preference. 3. The LMI has nothing to do with the encapsulation. As an example, Juniper routers can do Cisco LMI. They cannot do Cisco encapsulation though. You need to do whatever the frame-relay switch is set to, otherwise things just plain won't work! HTH, Scott Morris, CCIE4 (R&S/ISP-Dial/Security/Service Provider) #4713, JNCIE #153, CISSP, et al.

Hi, I donot understand the Lab30_R5/R6 Serial 4/0 config. The workbook says "Configure FR crkt on connected Routers and R5 such that PDU is RFC 2427 format. Make sure Router R6 still continues to send the default format to any future Cisco router connected to its Serial 4/0 interface link". I have few questions : 1. Why R5 Se4/0 is not configured with IETF whereas R6 Se4/0 is configured with the IETF. Isn;t suppose to be the other way round???. 2. Why you are configuring the DLCI twice in R6 Ser4/0 one with frame relay map command and the other with the interface DLCI. 3. Why are you configuring the LMI as Cisco ?
