| Explanation & Hint:
The consequence of configuring a router with the ipv6 unicast-routing global configuration command is that it enables the routing of IPv6 unicast datagrams on the router. This means that the router can process IPv6 routing information and make forwarding decisions for IPv6 packets.
Here are the specifics regarding the options provided:
- Each router interface will generate an IPv6 link-local address. This happens by default on IPv6-enabled interfaces, regardless of whether
ipv6 unicast-routing is configured.
- The IPv6 enabled router interfaces begin sending ICMPv6 Router Advertisement messages. This is true but it requires that the interfaces are configured with IPv6 addresses and that they are also configured to send these advertisements. Simply enabling IPv6 unicast routing does not automatically start the advertisement process.
- It statically creates a global unicast address on this router. This is not accurate. The
ipv6 unicast-routing command does not create any addresses on its own; global unicast addresses must be manually assigned or acquired via autoconfiguration processes.
- All router interfaces will be automatically activated. This is not correct. Interfaces must be configured and activated individually; the
ipv6 unicast-routing command does not affect the operational status of the interfaces.
So, the most direct consequence of the command in the context of the options provided is related to enabling the router to process and route IPv6 unicast traffic. It does not automatically activate interfaces or configure addresses. |
