This count includes invalid addresses, such as 0.0.0.0, and addresses of unsupported classes, e.g., Class E. For objects that do not act as IP gateways and therefore do not forward packets, this counter includes packets dropped because the destination address was not a local one (SNMP).

DGAUGE, count
Total external broadcast octets sent with IPv6 addresses and detailed traffic information (SNMP)
snmp6.ip6outdiscards
DGAUGE, count
Number of outgoing IPv6 packets encountering no issues preventing their transmission to the destination but still dropped, e.g., due to lack of buffer space.

DGAUGE, count
Total external multicast octets sent with IPv6 addresses and detailed traffic information (SNMP)
snmp6.ip6outmcastpkts
DGAUGE, count
Total external multicast packets sent with IPv6 addresses and detailed traffic information (SNMP)
snmp6.ip6outnoroutes
DGAUGE, count
Number of IPv6 packets dropped because no route to their destination was found (SNMP).

DGAUGE, count
Total external octets sent with IPv6 addresses and detailed traffic information (SNMP)
snmp6.ip6outrequests
DGAUGE, count
Total IPv6 packets provided by local IPv6 user-level protocols (including ICMP) to IPv6 in requests for transmission (SNMP).
snmp6.ip6reasmfails
DGAUGE, count
Number of failures detected by the IPv6 reassembly algorithm due to reasons, such as timeouts, errors, etc. This is not necessarily a count of dropped IPv6 fragments, since certain algorithms, like the one in RFC 815, may lose count of fragments while reassembling them as they are received (SNMP).
snmp6.ip6reasmoks
DGAUGE, count
Number of IPv6 packets successfully reassembled (SNMP)
snmp6.ip6reasmreqds
DGAUGE, count
Number of received IPv6 fragments requiring reassembly in the object in question (SNMP)
