Configuring IPv6 Unicast Routing
This chapter describes how to configure IPv6 unicast routing on the Cisco Industrial Ethernet Switches, hereafter referred
to as “switch.”
To use this feature, the switch must be running the IP services image. To enable IPv6 routing, you must configure the
switch to use a dual IPv4 and IPv6 switch database management (SDM) template. See Dual IPv4 and IPv6 Protocol
Stacks, page 930.
Note: For complete syntax and usage information for the commands used in this chapter, see the Cisco IOS
documentation listed in the Related Documents, page 956.

Information About IPv6
IPv4 users can move to IPv6 and receive services such as end-to-end security, quality of service (QoS), and globally
unique addresses. The IPv6 address space reduces the need for private addresses and Network Address Translation
(NAT) processing by border routers at network edges.
This section describes IPv6 implementation on the switch and includes the following topics:
 IPv6 Addresses, page 927
 Supported IPv6 Unicast Routing Features, page 928
 Unsupported IPv6 Unicast Routing Features, page 932
IPv6 Addresses
The switch supports only IPv6 unicast addresses. It does not support site-local unicast addresses, anycast addresses,
or multicast addresses.
The IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by colons in the
format: n:n:n:n:n:n:n:n. This is an example of an IPv6 address:
2031:0000:130F:0000:0000:09C0:080F:130B
