Configuring NTP for IPv6 on Cisco Networks

In my last blog I discussed Configuring HSRP for IPv6 on Cisco Networks.  Since it was already on my mind, I decided to continue the IPv6-oriented blogging and show how to configure and verify NTP for IPv6.  Let’s see how it works.

First, let’s see the topology I am using, shown in figure 1:

For instructor-led Cisco training see our CCNA class schedule.

Figure 1-NTP for IPv6 topology

I will not show the configuration of the IPv6 addresses on the interfaces or the routing (it is all static for this scenario), I will just show the IPv6 – NTP – related configs.

On R1, figure 2 shows the relevant config:

Figure 2-R1 NTP config

Figure 3 shows what is happening on R2:

Figure 3-R2 NTP config

It turns out that the IPv6 address shown in figure 3 is the IPv6 address that is on loopback 100 of R1.  The last piece is R3.  Figure 4 shows that:

Figure 4-R3 NTP config

In like manner, the IPv6 address shown in figure 4 is the IPv6 address that is configured on R2’s loopback 100 interface.

Now let’s verify NTP messages are occurring.  I issued a couple of debug commands on R2, shown in figure 5:

005-verify-NTP-messages-NTP-for-IPv6-on-Cisco-networks

Figure 5-R3 R2 debug output

Clearly I can verify that the NTP messages are appearing, and most assuredly they in IPv6 format!  I’m thinking this IPv6 thing is eventually going to take off!  J

Since we are here, let’s check the clock on R3:

Figure 6-R3 R3 show clock detail

And that’s the way it is, Friday, September 11th, 2015.

If you have any comments or questions, please feel free to post them….
Until next time.
