V1, 6.16 is a task about Frame Relay DE. The task indicates that HTTP traffic should be the least likely to be dropped when entering the FR cloud (but constrains you from using FRTS, GTS, or any MQC to make it happen). My solution matched the DSG, essentially building an ACL that matches everything other than WWW traffic, assigning that to a DE-list and applying the DE-group to the appropriate DLCIs.
I went a step further and disabled IP CEF for those frame-relay interfaces, because I knew that the de-group/de-list function only works on process switched traffic, per this note from the command reference: Frame Relay DE group functionality is supported on process-switched packets > only. I know this to be true because I once spent about 2 hours trying to figure out the seemingly inconsistent behavior of this feature before I found that little note. The DSG skips this and just applies the de-group, and then does a test by sending packets from the router interface to which the de-group is applied, and declares the task complete. Problem is, testing form the router's interface results in process-switched packets that hit the de-group. But transit packets through the router that are normally CEF switched would definitely not be marked by this feature. Was I right to disable CEF processing in order to ensure the de-group would actually mark the supposed WWW traffic that was going to come through it? Appreciate any insight or recommendations. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
