IPv6 Unicast Routing

Configuring IP Unicast Routing

This section describes the commands associated with configuring IP unicast routing on the switch. To

configure routing:

1 Create and configure two or more VLANs.

2 Assign each VLAN that will be using routing an IP address using the following command:

configure vlan <vlan_name> ipaddress [<ipaddress> {<ipNetmask>} | ipv6-link-local

| {eui64} <ipv6_address_mask>]

Ensure that each VLAN has a unique IP address.

3 Configure a default route using the following command:

configure iproute add default [<ipv6Gateway> | <ipv6ScopedGateway>] {vr <vrname>}

{<metric>} {multicast-only | unicast-only}

Default routes are used when the router has no other dynamic or static route to the requested

destination.

4 Turn on IP routing for one or all VLANs using the following command:

enable ipforwarding ipv6 {vlan <vlan_name> | tunnel <tunnel-name> | vr <vr_name>}

5 Configure the routing protocol, if required. For a simple network using RIPng, the default

configuration may be acceptable.

6 Turn on RIPng or OSPFv3 using one of the following commands:

enable ripng

enable ospfv3 {domain <domainName>}

Verifying the IP Unicast Routing Configuration

Use the show iproute ipv6 command to display the current configuration of IP unicast routing for the

switch and for each VLAN. The

show iproute ipv6 command displays the currently configured

routes and includes how each route was learned.

Additional verification commands include:

● show neighbor-discovery cache ipv6—Displays the neighbor discovery cache of the system.

● show ipconfig ipv6—Displays configuration information for one or more VLANs.

Routing Configuration Example

Figure 63 illustrates a BlackDiamond switch that has three VLANs defined as follows:

● Finance

■ Protocol-sensitive VLAN using IPv6 protocol

■ All ports on slots 1 and 3 have been assigned.

■ IP address 2001:db8:35::1/48.

● Personnel

■ Protocol-sensitive VLAN using the IPv6 protocol.

■ All ports on slots 2 and 4 have been assigned.
