IPv6 Addressing

•The Cisco ANA NetworkVision VRF table does not display IPv6 VRF routing information.

•If an interface or subinterface does not have an IPv4 or IPv6 IP address, the interface is not discovered and not shown in Cisco ANA NetworkVision.

•The Layer 1 topology between 6VPE and an IPv6 CE is discovered only when CDP is enabled.

•BGP neighbor discovery does not occur between PE and CE interfaces configured with IPv6 addresses only.

•Correlation flows between IPv6-only interfaces is not supported.

IPv6 Addressing

IPv6 addresses are 128-bit identifiers for interfaces and sets of interfaces. Cisco ANA supports the following IPv6 address types:

•Unicast—Identifier for a single interface. A packet sent to a unicast address is delivered to the interface identified by that address.

•Anycast—Identifier for a set of interfaces (typically belonging to different nodes). A packet sent to an anycast address is delivered to one of the interfaces identified by that address (the “nearest” one, according to how the routing protocol measures distance.

•Multicast—Identifier for a set of interfaces (typically belonging to different nodes). A packet sent to a multicast address is delivered to all interfaces identified by that address.

Cisco ANA supports interfaces with multiple IPv6 addresses. The lowest IPv6 address is presented in the Cisco ANA tables; all addresses are shown in the detailed interface properties view. Cisco ANA does not model link-local unicast addresses because they are not used in the routing and forwarding tables.

The following sections provide additional IPv6 address format information:

•IPv6 Address Representation, page 6-6

•IPv6 Address Prefix Text Representation, page 6-7

Note For more IPv6 addressing information, see “RFC2460 - Internet Protocol, Version 6 (IPv6 Specification.”

IPv6 Address Representation

IPv6 has three conventional text string representation forms. The preferred form is x:x:x:x:x:x:x:x, where x is the hexadecimal value of the eight 16-bit address pieces, for example:

FEDC:BA98:7654:3210:FEDC:BA98:7654:3210

1080:0:0:0:8:800:200C:417A

Because IPv6 addresses frequently contain long strings of zero bits, two colons (::) can be used to indicate multiple 16-bit groups of zeros. Table 6-3shows examples.
