While the minimum supported MTU size was 576 Bytes with IPv4, with IPv6 this minimum has increased to 1280 Bytes.

RIP (like other IPv6 routing protocols) is enabled on the interface, this is done with the ipv6 rip name enable command. The ipv6 router rip name command is used to change process-wide variables (like maximum paths). Another example is OSPF. This is configured under an interface with ipv6 ospf 1 area 0, for example. Notice the process ID is set to 1 and the area is the backbone (0).

IPv6 ACL statements are very similar to IPv4 ACL statements except wildcard marks are not used; in this case the permit tcp any 2001::/64 eq ssh statement accomplishes the goals, allowing traffic from any source to pass to the 2000::/64 network over SSH.

The need for a DHCP relay agent with IPv6 is the same as it is with IPv4; the configuration is slightly different but the operation is similar at a high level. The ipv6 dhcp relay destination ipv6-address command is used on the router that connects to the client segment and points to the unicast address of the DHCP server.

The Network Prefix Translation (NPTv6) feature is used to translate between an outside IPv6 global prefix to an inside unique local or separate global prefix.

A Hosts (AAAA) record is used to resolve a Fully Qualified Domain Name (FQDN) to a IPv6 address.
