Everything appears to be working, but extremely slow. I've done ping6 to both ipv6.he.net and ipv6.google.com and noticed a that the average pings were 95+ ms with 80% packet loss. The he.net server that I use is local and distance should not be an issue. Any assistance would be appreciated. IPv4 ToS/IPv6 traffic class byte In an IPv6 packet, the Traffic Class byte is used in the same way as the ToS byte in an IPv4 packet. A ToS/Traffic Class byte includes a DSCP codepoint and precedence bits: Differentiated Services Codepoint (DSCP) Consists of the upper six bits of the ToS/Traffic Class byte. There are 64 possible codepoints. 2.2.4.4 Packet Tracer – Configuring IPv6 Static and

IPv6 Extension Headers Review and Considerations [IP The packet shown in Figure 4 has a 72 bytes long EH chain, which means that a hardware forwarding platform that was designed to handle 64 bytes of EH data will have to software switch this packet. With the current IPv6 applications and services however, this would be an infrequent event. Internet Protocol version 6 (IPv6) Header - GeeksforGeeks Sep 21, 2017 On Link in IPv6 - Packet Pushers Ah, yes — the RA can contain a notification for an entire prefix, rather than just a single host. However, when you’re working with an IPv6 network you shouldn’t assume that just because two hosts are in the same subnet, based on the prefix and prefix length, that they will be considered “on link,” by … UVerse Internet IPv6 packet loss serious issue | AT&T
