Hi All,
I'm getting the following error "Received packet without a valid source
address!!!" on sgsnemu 0.84

The error I get on GGSN (Cisco 7200) on debugging is "Mandatory info element out of
sequence"
*Oct 13 17:01:42.444: GTP IE:4200113254769800:rcvd 0 out of order previous IE 0
*Oct 13 17:01:42.448: %GTP-2-PDPACTIVATIONFAIL: GTP PDP activation/update failed, GSN:
0.0.0.0, TID: 00, Reason: Mandatory info element out of sequence
I'm sticking with 0.84 as 0.91 has a bug while sending echo " Mandatory IE
invalid" . Any help on this is greatly appreciated.
Thank you,
Anish
