Static IPv6 routing, an explicit route between two IPv6 networking devices

Page 249 highlights

To enable stateless autoconfiguration of an IPv6 global address and set the interface to Host mode, use the ipv6 address autoconfig command. The router receives network prefixes in IPv6 router advertisements (RAs). An interface ID is appended to the prefix. In Host mode, IPv6 forwarding is disabled. The no ipv6 address autoconfig command disables IPv6 global address autoconfiguration, and sets the interface to Router mode with IPv6 forwarding enabled. DHCP-assigned addresses As an alternative to stateless autoconfiguration, you can enable a network host to obtain IPv6 addresses using a DHCP server via stateful autoconfiguration using the ipv6 address dhcp command. A DHCPv6 server uses a prefix pool to configure a network address on an interface. The interface ID is automatically generated. Manally configured addresses An interface can have multiple IPv6 addresses. To configure an IPv6 address in addition to the link-local address, use the ipv6 address ipv6-address/mask command. Enter the full 128-bit IPv6 address, including the network prefix and a 64-bit interface ID. You can also manually configure an IPv6 address by assigning: • A network prefix with the EUI-64 parameter using the ipv6 address ipv6-prefix eui64 command. A 64-bit interface ID is automatically generated based on the MAC address. • A link-local address to use instead of the link-local address that is automatically configured when you enable IPv6 using the ipv6 address link-local command. Configure IPv6 address OS10(config)# interface ethernet 1/1/8 OS10(conf-if-eth1/1/8)# ipv6 address 2001:dddd:0eee::4/64 Configure network prefix OS10(config)# interface ethernet 1/1/8 OS10(conf-if-eth1/1/8)# ipv6 address 2001:FF21:1:1::/64 eui64 Configure link-local address OS10(config)# interface ethernet 1/1/8 OS10(conf-if-eth1/1/8)# ipv6 address FE80::1/64 link-local Static IPv6 routing To define an explicit route between two IPv6 networking devices, configure a static route on an interface. Static routing is useful for smaller networks with only one path to an outside network, or to provide security for certain traffic types in a larger network. • Enter the static routing information including the IPv6 address and mask in x:x:x:x::x format in CONFIGURATION mode-prefix length 0 to 64. ipv6 route ipv6-prefix/mask {next-hop | interface interface [route-preference]} • next-hop - Enter the next-hop IPv6 address in x:x:x:x::x format. • interface interface - Enter the interface type then the slot/port or number information. • route-preference - (Optional) Enter a route-preference range-1 to 255. After you configure a static IPv6 route, configure the forwarding router's address on the interface. The IPv6 neighbor interface must have an IPv6 address configured. Layer 3 249

To enable stateless
autoconfiguration
of an IPv6 global address and set the interface to Host mode, use the
ipv6 address
autoconfig
command. The router receives network
prefixes
in IPv6 router advertisements (RAs). An interface ID is appended to the
prefix.
In Host mode, IPv6 forwarding is disabled.
The
no ipv6 address autoconfig
command disables IPv6 global address
autoconfiguration,
and sets the interface to Router mode
with IPv6 forwarding enabled.
DHCP-assigned addresses
As an alternative to stateless
autoconfiguration,
you can enable a network host to obtain IPv6 addresses using a DHCP server via stateful
autoconfiguration
using the
ipv6 address dhcp
command. A DHCPv6 server uses a
prefix
pool to
configure
a network address on an
interface. The interface ID is automatically generated.
Manally
configured
addresses
An interface can have multiple IPv6 addresses. To
configure
an IPv6 address in addition to the link-local address, use the
ipv6 address
ipv6-address/mask
command. Enter the full 128-bit IPv6 address, including the network
prefix
and a 64-bit interface ID.
You can also manually
configure
an IPv6 address by assigning:
A network
prefix
with the EUI-64 parameter using the
ipv6 address
ipv6-prefix
eui64
command. A 64-bit interface ID is
automatically generated based on the MAC address.
A link-local address to use instead of the link-local address that is automatically
configured
when you enable IPv6 using the
ipv6
address link-local
command.
Configure
IPv6 address
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2001:dddd:0eee::4/64
Configure
network
prefix
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address 2001:FF21:1:1::/64 eui64
Configure
link-local address
OS10(config)# interface ethernet 1/1/8
OS10(conf-if-eth1/1/8)# ipv6 address FE80::1/64 link-local
Static IPv6 routing
To
define
an explicit route between two IPv6 networking devices,
configure
a static route on an interface. Static routing is useful for smaller
networks with only one path to an outside network, or to provide security for certain
traffic
types in a larger network.
Enter the static routing information including the IPv6 address and mask in x:x:x:x::x format in CONFIGURATION
mode—prefix
length
0 to 64.
ipv6 route
ipv6–prefix
/
mask
{next-hop | interface
interface
[
route-preference
]}
next-hop
— Enter the next-hop IPv6 address in x:x:x:x::x format.
interface
interface
— Enter the interface type then the slot/port or number information.
route-preference
— (Optional) Enter a route-preference range—1 to 255.
After you
configure
a static IPv6 route,
configure
the forwarding router’s address on the interface. The IPv6 neighbor interface must have
an IPv6 address
configured.
