Hi All

in my sgsn log I am getting

Am I getting PDP deactivation because of routing area reject. Also noticed that TLLI changes from Activate PDP context. This TLLI is based on TMSI/P-TMSI Upto Attach complete procedure I have different TLLI.

For setup I have

BSC, SGSN on eth0 and eth0:1 respectively and GGSN on eth1 ( I have external network adapter).

Can anybody suggest something why I am not getting pdp deactivation.
