Enabling IPv6 routing
44
• Configure the IPv6 neighbor discovery feature.
• Change the IPv6 MTU.
• Configure an unnumbered interface.
• Configure static neighbor entries.
• Limit the hop count of an IPv6 packet.
• Configure Quality of Service (QoS) for IPv6 traffic
Enabling IPv6 routing
By default, IPv6 routing is disabled. To enable the forwarding of IPv6 traffic globally on the router,
enter the following command.
BigIron RX(config)# ipv6 unicast-routing
Syntax: [no] ipv6 unicast-routing
To disable the forwarding of IPv6 traffic globally on the Brocade device, enter the no form of this
command.
Configuring IPv6 on each router interface
To forward IPv6 traffic on a router interface, the interface must have an IPv6 address, or IPv6 must
be explicitly enabled. By default, an IPv6 address is not configured on a router interface.
If you choose to configure a global or site-local IPv6 address for an interface, IPv6 is also enabled
on the interface. Further, when you configure a global or site-local IPv6 address, you must decide
on one of the following in the low-order 64 bits:
• A manually configured interface ID.
• An automatically computed EUI-64 interface ID.
If you prefer to assign a link-local IPv6 address to the interface, you must explicitly enable IPv6 on
the interface, which causes a link-local address to be automatically computed for the interface. If
preferred, you can override the automatically configured link-local address with an address that you
manually configure.
This section provides the following information:
• Configuring a global or site-local address with a manually configured or automatically
computed interface ID for an interface.
• Automatically or manually configuring a link-local address for an interface.
• Configuring IPv6 anycast addresses
Configuring a global or site-local IPv6 address
Configuring a global or site-local IPv6 address on an interface does the following:
• Automatically configures an interface ID (a link-local address), if specified.
• Enables IPv6 on that interface.
