Make your config more uniform
ip hello-interval eigrp 1001 20 ip hold-time eigrp 1001 60 Need to change the hold time as the default over NBMA networks is 180 seconds On your R5 config you have > ip hold-time eigrp 1001 15 So when a hello comes in at 20 secs R5 resets the session as it has not received it within a 15 sec holdown -- BR Tony Sent from my iPad On 5 Jul 2013, at 22:38, "Jim Newell" <[email protected]> wrote: > This is in regard to Workbook 1, Lab 9, Task 9.9.
