Cisco ASA Series CLI Configuration Guide
Appendix 1 Addresses, Protocols, and Ports
IPv6 Addresses
•
An anycast address cannot be assigned to an IPv6 host; it can only be assigned to an IPv6 router.
Note
Anycast addresses are not supported on the ASA.
Required Addresses
IPv6 hosts must, at a minimum, be configured with the following addresses (either automatically or
manually):
•
A link-local address for each interface
•
The loopback address
•
The All-Nodes multicast addresses
•
A Solicited-Node multicast address for each unicast or anycast address
IPv6 routers must, at a minimum, be configured with the following addresses (either automatically or
manually):
•
The required host addresses
•
The Subnet-Router anycast addresses for all interfaces for which it is configured to act as a router
•
The All-Routers multicast addresses
IPv6 Address Prefixes
An IPv6 address prefix, in the format ipv6-prefix/prefix-length, can be used to represent bit-wise
contiguous blocks of the entire address space. The IPv6-prefix must be in the form documented in RFC
2373 where the address is specified in hexadecimal using 16-bit values between colons. The prefix
length is a decimal value that indicates how many of the high-order contiguous bits of the address
comprise the prefix (the network portion of the address). For example, 2001:0DB8:8086:6502::/32 is a
valid IPv6 prefix.
The IPv6 prefix identifies the type of IPv6 address.
shows the prefixes for each IPv6 address
type.
