12.2(33)SRC3

Description (partial)

Symptom:
 
 The problem arises during L2TP tunnel setup (initiator is the GGSN). The LNS 
 replies with a L2TP SCCRP packet containing two vendor specific AV pairs 
 (type 110 and 111).
 These two AV pairs cause an issue on the another manufacturer's GGSN device.
(kind of a memory leak) 
 preventing L2TP tunnel opening and consuming resources on the Flexi itself.
 
 Conditions:
 
 The problem arises during L2TP tunnel setup.
