Configuring IPv6 Unicast Routing
Information About IPv6
If you try to configure IPv6 without first selecting a dual IPv4 and IPv6 template, a warning message appears.
In IPv4-only environments, the switch routes IPv4 packets and applies IPv4 QoS and ACLs in hardware. IPv6 packets
are not supported.
In dual IPv4 and IPv6 environments, the switch routes both IPv4 and IPv6 packets and applies IPv4 QoS in hardware.
IPv6 QoS is not supported.
If you do not plan to use IPv6, do not use the dual stack template because it results in less hardware memory
availability for each resource.
DHCP for IPv6 Address Assignment
DHCPv6 enables DHCP servers to pass configuration parameters, such as IPv6 network addresses, to IPv6 clients. The
address assignment feature manages nonduplicate address assignment in the correct prefix based on the network where
the host is connected. Assigned addresses can be from one or multiple prefix pools. Additional options, such as default
domain and DNS name-server address, can be passed back to the client. Address pools can be assigned for use on a
specific interface, on multiple interfaces, or the server can automatically find the appropriate pool.
Static Routes for IPv6
Static routes are manually configured and define an explicit route between two networking devices. Static routes are
useful for smaller networks with only one path to an outside network or to provide security for certain types of traffic in
a larger network.
RIP for IPv6
Routing Information Protocol (RIP) for IPv6 is a distance-vector protocol that uses hop count as a routing metric. It
includes support for IPv6 addresses and prefixes and the all-RIP-routers multicast group address FF02::9 as the
destination address for RIP update messages.
OSPF for IPv6
The switch supports Open Shortest Path First (OSPF) for IPv6, a link-state protocol for IP.
EIGRP IPv6
The switch supports Enhanced Interior Gateway Routing Protocol (EIGRP) for IPv6. It is configured on the interfaces on
which it runs and does not require a global IPv6 address.
Before running, an instance of EIGRP IPv6 requires an implicit or explicit router ID. An implicit router ID is derived from a
local IPv4 address, so any IPv4 node always has an available router ID. However, EIGRP IPv6 might be running in a
network with only IPv6 nodes and therefore might not have an available IPv4 router ID.
Multiprotocol BGP for IPv6
Multiprotocol Border Gateway Protocol (BGP) is the supported exterior gateway protocol for IPv6. Multiprotocol BGP
extensions for IPv6 support the same features and functionality as IPv4 BGP. IPv6 enhancements to multiprotocol BGP
include support for IPv6 address family and network layer reachability information (NLRI) and next-hop (the next router
in the path to the destination) attributes that use IPv6 addresses.
The switch does not support multicast BGP or non-stop forwarding (NSF) for IPv6 or for BGP IPv6.
