Configuring IP Information Management and IP Interfaces 16 • IPv6 Address-The switch supports one IPv6 interface. In addition to the default link local and Multicast addresses, the device also automatically adds global addresses to the interface based on the router advertisements it receives. The device supports a maximum of 128 addresses at the interface. Each address must be a valid IPv6 address that is specified in hexadecimal format by using 16-bit values separated by colons. NOTE You cannot configure an IPv6 addresses directly on an ISATAP tunnel interface. • Prefix Length-The length of the Global IPv6 prefix is a value from 0-128 indicating the number of the high-order contiguous bits of the address comprise the prefix (the network portion of the address). • EUI-64-Select to use the EUI-64 parameter to identify the interface ID portion of the Global IPv6 address by using the EUI-64 format based on a device MAC address. STEP 5 Click Apply. The Running Configuration file is updated. Defining an IPv6 Default Router List The IPv6 Default Router List page enables configuring and viewing the default IPv6 router addresses. This list contains the routers that are candidates to become the switch default router for non-local traffic (it may be empty). The switch randomly selects a router from the list. The switch supports one static IPv6 default router. Dynamic default routers are routers that have sent router advertisements to the switch IPv6 interface. When adding or deleting IP addresses, the following events occur: • When removing an IP interface, all the default router IP addresses are removed. • Dynamic IP addresses cannot be removed. • An alert message is displayed after an attempt is made to insert more than a single user-defined address. • An alert message is displayed when attempting to insert a non-link local type address, meaning 'fe80:'.
