                                    0 - no route to destination
                                    1 - communication with destination administratively prohibited
                                    2 - beyond scope of source address
                                    3 - address unreachable
                                    4 - port unreachable
                                    5 - source address failed ingress/egress policy
                                    6 - reject route to destination
                                    7 - Error in Source Routing Header
----------------------------------------------------- 
2     Packet Too Big
                                    0 - Packet too big
----------------------------------------------------- 
3     Time Exceeded
                                    0 - hop limit exceeded in transit
                                    1 - fragment reassembly time exceeded
----------------------------------------------------- 
                                   
4     Parameter Problem 
                                    0 - erroneous header field encountered
                                    1 - unrecognized Next Header type encountered
                                    2 - unrecognized IPv6 option encountered
