Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4
- Anycast—The IPv6 address is an Anycast address. This is an address that is
assigned to a set of interfaces that typically belong to different nodes. A packet sent
to an Anycast address is delivered to the closest interface—as defined by the routing
protocols in use—identified by the Anycast address.
Anycast cannot be used, if the IPv6 address is on an ISATAP interface.
NOTE
• IPv6 Address—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.
The following types of addresses can be added to various types of tunnels:
- To manual tunnels—Global or Anycast address
- To ISATAP tunnels—Global address with EUI-6
- 6 to 4 tunnels—None
• 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.
Click Apply. The Running Configuration file is updated.
