Description (partial)

When an ipv6 acl is applied on interface and if rule has fragments keyword, match is not happening properly

ipv6 access-list V6FragTst
10 permit ipv6 any any fragments >> Should match here.
100 permit ipv6 any any (150802 matches)

This happens when incoming packet is MPLS packet coming with aggregate label and packet has fragment header. In this case, it should have done proper ACL along with IP lookup.
