Configuring IPv4 and IPv6 protocol stacks
If a device is deployed as an endpoint for an IPv6 over IPv4 tunnel, you must configure the device to
support IPv4 and IPv6 protocol stacks. Each interface that sends and receives IPv4 and IPv6 traffic
must be configured with an IPv4 address and an IPv6 address. You can also explicitly enable IPv6
using the ipv6 enable command. Refer to
“Configuring a link-local IPv6 address”
To configure an interface to support both IPv4 and IPv6 protocol stacks, enter commands such as
the following.
Brocade(config)# ipv6 unicast-routing
Brocade(config)# interface ethernet 3/1
Brocade(config-if-e100-3/1)# ip address 192.168.1.1 255.255.255.0
Brocade(config-if-e100-3/1)# ipv6 address 2001:DB8:12d:1300::/64 eui-64
These commands globally enable IPv6 routing on the device, 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 Brocade device, enter the no form of this command.
Syntax: [no] 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: [no] ipv6 address ipv6-prefix/prefix-length [eui-64]
This syntax specifies a global or unique local IPv6 unicast address. For information about
configuring a link-local IPv6 address, refer to
“Configuring a link-local IPv6 address”
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 unique local unicast 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 MAC address of the interface. 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
