How to configure IPv6 Static Route

Lessons Discussion

Hi ,

If you try this with a FastEthernet interface, you’ll see that the router will accept the command, but the ping won’t work. You can’t use this for multi-access interfaces.

Why we can’t use them in Multi-access Interfaces? Thank you.

Hello Görgen

In the lesson, there are many different operations that are applied, so I’m not sure which one you are referring to when you say “if you try this…” I assume you mean if we have a FastEthernet interface instead of a serial link as in the lesson, correct?

If so, then the configuration of an IPv6 address on either a serial link or a FastEthernet link should still have the same results. It’s a layer 3 address which is accessible regardless of what Layer 2 technology you are using. Does that make sense?

If however, your question pertained to something else, please clarify so that I can help you further.

I hope this has been helpful!

Hi Lazar

Sorry for lack of explanation.

This is the exact same sentence from the lesson.

If you try this with a FastEthernet interface, you’ll see that the router will accept the command, but the ping won’t work. You can’t use this for multi-access interfaces.

Why we can’t use FastEthernet interfaces as Multiaccess?

Thanks

Hello Görgen

Ah, I see, that was a quote from the lesson. Thanks for the clarification.

Now what Rene is saying here is that if you try to create a static route using only an exit interface that is a multi-access interface such as an Ethernet interface, the command will be accepted. However, if you ping that destination, there will be no response.

The reason for this is that a multiaccess interface such as an Ethernet interface, may have multiple hosts connected to it. So specifying just an exit interface is not enough. You must enter a fully specified route. This is the case for both IPv4 and IPv6.

With a point to point technology such as a serial link, there is only a single host that can be connected on the other end of the link, therefore, specifying only an exit interface is enough to make it work. Check out this NetworkLessons note for more information.

I hope this has been helpful!
