- 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
- 6to4 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).
• DAD Status—Whether Duplicate Access Detection is active or not.
• 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.
