IPv4 and IPv6 address families

“

- We now want to look at using IPv4 and IPv6, address families. We know that BGP has a multi protocol capability, meaning that it is capable of carrying various routing protocols over a single session. And this is possible using address families. This allows us to advertise both IPv4 and IPv6 to appear over a single BGP session. You can see in our topology, we have two directly connected routers and the interfaces are configured for both IPv4 and IPv6. R1 is in AS 65,100 and R2 is in AS 65,200. Again, we're going to build a single BGP session between these routers, and advertise both IPv6 and IPv4. If we connect to router one and say, show run, interface, gig 0/0 we'll be able to see that we are configured with both an IP version four address that we see here, and an IP version six address on our interface gig 0/0. Let's jump over to router two. We'll do the same verification, show run interface gig 0/0. Again, we see IP version four and IP version six configured on our interface…
