ipv6 router vs router ... commands

[jon_panes24]

Hi

I was just wondering whats the difference between the commands:

ipv6 router ospf 1 vs router ospfv3 1

it noticed that if you have used either one you cant use the other command even if it is in the same process.ex ipv6 router ospf 1. If i use router ospfv3 1 it will give an error prompt.

Thanks

Hi,

the ipv6 router ospf <pid> command creates a process for IPv6 only.

With the router ospfv3 <pid> command, support for Address Families was introduced (similar to AFs used by BGP, EIGRP and IS-IS), so you can run IPv4 and IPv6 under the same process.

There is an interesting Cisco Live Session where this relatively new feature was presented too: BRKRST-2337 - OSPF Deployment in Modern Networks
