Re: IPv6 migration steps for mid-scale isp

Thank you all for your Ideas. AFAIK one of the main decisions for IPv6 transition and deployment is the choice of IPv6 IGP. I read somewhere that its a good practice to use different IGP protocol for IPv6 and IPv4. For example if IGP for IPv4 is IS-IS then use OSPFv3 for IPv6. any comments on this?

I've never heard this promoted as good practice - why on earth would you want to make life more difficult for yourself by running two IGPs if you can run one? Yes, if you use OSPF for IPv4 you *have* to use something else for IPv6. But if you already run IS-IS there is no reason to change, just remember to enable multi-topology.
