B. Publish an address as part of a static route.
When a route for an IPv6 address on a given Ethernet interface is created, IPv6 should already
be enabled for the interface which means that IPv6 neighbor discovery is operational.
Optionally, Proxy Neighbor Discovery (Proxy ND) can also be enabled for an IPv6 route so that
all or selected interfaces will also respond to any neighbor solicitations for the route's
network.
An example of using this second method is given below.
Example 3.13. Adding an IPv6 Route and Enabling Proxy ND
Assume that a route needs to be in the main routing table so that the IPv6 network my_ipv6_net
is routed on the interface If1 where that interface already has IPv6 enabled.
In addition, proxy neighbor discovery for my_ipv6_net needs to be enabled for the If3 interface.
Command-Line Interface
First, change the CLI context to be the main routing table:
gw-world:/> cc RoutingTable main
Add the IPv6 route:
gw-world:/main> add Route6 Network=my_ipv6_net
Interface=If1
ProxyNDInterfaces=If3
Lastly, return to the default CLI context:
gw-world:/main> cc
gw-world:/>
Web Interface
1. Go to: Network > Routing > Routing Tables > main > Add > RouteIPv6
2. Now enter:
• Interface: If1
• Network: my_ipv6_net
3. Go to: Proxy ND and move the interface If3 from Available to Selected
4. Click OK
Troubleshooting IPv6 with ICMP Ping
The CLI command ping can be used for both IPv4 and IPv6 addresses. For example:
gw-world:/> ping 2001:DB8::2
This provides the means to determine if an IPv6 host is reachable and responding.
