IPv6 Address—In Layer 2, the device supports a singleIPv6 interface
In addition to the default link local and Multicast addresses, the device
also automatically adds global addresses to the interface based on the
router advertisements it receives The device supports a maximum of 128
addresses at the interface Each address must be a valid IPv6 address that is
specified in hexadecimal format by using 16-bit values separated by colons
•
Prefix Length—The length of the Global IPv6 prefix is a value from 3-128
indicating the number of the high-order contiguous bits of the address
that comprise the prefix (the network portion of the address)
•
EUI-64—Select to use the EUI-64 parameter to identify the interface ID
portion of the Global IPv6 address on a device MAC address
STEP 5 Click Apply The Running Configuration file is updated
IPv6 Default Routers
The IPv6 Default Routers page enables configuring and viewing the default
IPv6 router addresses This list contains the routers that are candidates to
become the device default router for nonlocal traffic (it may be empty) The
device randomly selects a router from the list The device supports one static
IPv6 default router Dynamic default routers are routers that have sent router
advertisements to the device IPv6 interface
When adding or deleting IP addresses, the following events occur:
•
When removing an IP interface, all the default router IP addresses are
removed Dynamic IP addresses cannot be removed
•
An alert message appears after an attempt is made to insert more than
a single user-defined address
•
An alert message appears when attempting to insert a non-link local
type address, meaning ‘fe80:’
To define a default router, do the following:
STEP 1 Click Configuration > IP Interface> IPv6 > IPv6 Default Routers
This page displays the following fields for each default router:
•
Default Router IPv6 Address—Link local IP address of the default router
•
IPv6 Interface—Outgoing IPv6 interface where the default router resides
•
State—Whether route is reachable or unreachable
•
Type—The default router configuration that includes the following options:
•
Static—The default router was manually added to this table through the
Add button
•
Dynamic—The default router was dynamically configured
STEP 2 Click Add to add a static default router
STEP 3 Enter the following fields:
•
IPv6 Interface—Displays the outgoing Link Local interface
•
Default Router IPv6 Address—The IP address of the default router
STEP 4 Click Apply The default router is saved to the Running
Configuration file
IPv6 Routes
The IPv6 Forwarding Table contains the various routes that have been
configured One of these routes is a default route (IPv6 address:0) that uses
the default router selected from the IPv6 Default Router List to send packets
to destination devices that are not in the same IPv6 subnet as the device In
addition to the default route, the table also contains dynamic routes that are
ICMP redirect routes received from IPv6 routers by using ICMP redirect messages
This could happen when the default router the device uses is not the router for
traffic to which the IPv6 subnets that the device wants to communicate
To view IPv6 routes:
STEP 1 Configuration > IP Interface > IPv6 > IPv6 Routes
This page displays the following fields:
•
IPv6 Subnet Address—The IPv6 subnet address
•
Prefix Length—IP route prefix length for the destination IPv6 subnet
address It is preceded by a forward slash
•
IPv6 Interface—Interface used to forward the packet
•
Next Hop Router IPv6 Address—Address where the packet is forwarded
Typically, this is the address of a neighboring router It can be one of the
following types
•
Link Local—An IPv6 interface and IPv6 address that uniquely
identifies hosts on a single network link A link local address has a
prefix of FE80, is not routable, and can be used for communication
only on the local network
