host's address. Routers have their network prefixes configured and may use EUI-64 or manually configured interface IDs. In addition to zero or more global addresses, each IPv6 interface also has an autoconfigured "link-local" address which is: • fe80::/10, with the EUI-64 address in the least significant bits. • Reachable only on the local VLAN - link-local addresses are never routed. • Not globally unique Next hop addresses computed by routing protocols are usually link-local addresses. During the period of transitioning the Internet to IPv6, a global IPv6 Internet backbone may not be available. One transition mechanism is to tunnel IPv6 packets inside IPv4 to reach remote IPv6 islands. When a packet is sent over such a link, it is encapsulated in IPv4 in order to traverse an IPv4 network and has the IPv4 headers removed at the other end of the tunnel. Default IPv6 Routing Values IPv6 is disabled by default on the switch and on all interfaces. Table 38-1 shows the default values for the IP routing features this chapter describes. Table 38-1.
