5.3.0.BASE

Description (partial)

Symptom:
When "show cef vrf <VRFNAME> lisp decapsulation" or variations of this command are issued for the first time for a given VRF, a small amount of data (on the order of 40 bytes) is leaked. This data represents lisp information pertinent to decapsulation on the given VRF. If LISP is not running in the VRF, then this leak will not happen.  This leak would happen at the point where LISP is no longer in use on the VRF.

Conditions:
If LISP Is configured to decapsulate traffic on a VRF, and the command "show cef vrf <VRFNAME> lisp decapsulation" is issued for the first time on against the VRF, then a small amount of data (on the order of 40 bytes) is leaked. This leak would happen at the point where LISP is no longer in use on the VRF.
