Configuring IPv4 and IPv6 protocol stacks

Configuring IPv4 and IPv6 protocol stacks
One situation in which you must configure a router to run both IPv4 and IPv6 protocol stacks is if it
is deployed as an endpoint for an IPv6 over IPv4 tunnel.
Each router interface that you want to send and receive both IPv4 and IPv6 traffic must be
configured with an IPv4 address and an IPv6 address. (An alternative to configuring a router
interface with an IPv6 address is to explicitly enable IPv6 using the ipv6 enable command. For
more information about using this command, refer to
page 1085.)
To configure a router interface to support both the IPv4 and IPv6 protocol stacks, use commands
such as the following.
BigIron RX(config)# ipv6 unicast-routing
BigIron RX(config)# interface ethernet 3/1
BigIron RX(config-if-e100-3/1)# ip address 192.168.1.1 255.255.255.0
BigIron RX(config-if-e100-3/1)# ipv6 address 2001:200:12d:1300::/64 eui-64
These commands globally enable IPv6 routing on the router and configure an IPv4 address and an
IPv6 address for Ethernet interface 3/1.
Syntax: [no] ipv6 unicast-routing
To disable IPv6 traffic globally on the router, enter the no form of this command.
Syntax: ip address <ip-address> <sub-net-mask> [secondary]
You must specify the <ip-address> parameter using 8-bit values in dotted decimal notation.
You can specify the <sub-net-mask> parameter in either dotted decimal notation or as a decimal
value preceded by a slash mark (/).
The secondary keyword specifies that the configured address is a secondary IPv4 address.
To remove the IPv4 address from the interface, enter the no form of this command.
Syntax: ipv6 address <ipv6-prefix>/<prefix-length> [eui-64]
This syntax specifies a global or site-local IPv6 address. For information about configuring a
link-local IPv6 address, refer to
You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
You must specify the <prefix-length> parameter as a decimal value. A slash mark (/) must follow
the <ipv6-prefix> parameter and precede the <prefix-length> parameter.
The eui-64 keyword configures the global or site-local address with an EUI-64 interface ID in the
low-order 64 bits. The interface ID is automatically constructed in IEEE EUI-64 format using the
interface's MAC address. If you do not specify the eui-64 keyword, you must manually configure the
64-bit interface ID as well as the 64-bit network prefix. For more information about manually
configuring an interface ID, refer to
