Known Affected Releases

7.0(3)I7(3)

Description (partial)

Symptom:
we saw - Even if ip is not given as a match filed, tcam entries are getting installed with Zero'ed IP(IPV6) values with random Mask.? That is why traffic is not hitting specific V6 rules, rather default DROP is hit.
However, If both IPs (src & dst) are given as match fields, things work as expected.

Conditions:
If IPV6 src and destination fields are empty in the filter then tcam enrty add zero values in the source and destination field.
