Hi, I received 12 responses for the query that i had put up. o 1 response stated that the provider was using IS-IS for IPv6 and not using any authentication. o 7 responses where OSPFv3 was being used without any authentication. o 2 responses where OSPFv3 is being used with authentication o 2 responses where they were using OSPFv2 with authentication turned on. I asked the 7 people who had replied in negative about why they were not using authentication with OSPFv3. 5 responded stating a mix of the following reasons: o IPsec not available on all platforms o IPsec required interoperability testing, which was perceived as a hassle o Troubleshooting becomes much harder. OSPF operation should be kept as simple as possible, especially when used in the core. o Complex configuration o Required coordination between different boxes which is a deterrent. o IPSec on some platforms requires a special license which can be expensive. o Unsure of how well is the IPsec implemented on the boxes Cheers, Manav On Tue, Sep 28, 2010 at 5:33 AM, Manav Bhatia <manavbhatia@gmail.com> wrote:

Hi,

I am doing a survey and was interested in knowing if network operators are using OSPFv3 with authentication [RFC 4552] turned on? I know that most providers turn on authentication with OSPFv2, but given that OSPFv3 needs IPsec integration and can thus get little cumbersome to configure, wanted to understand if a similar % of folks also turn on authentication for OSPFv3?

You can unicast me your responses (if you dont wish to share it on the list) and i will collate all data and post a summary on the list.

Cheers, Manav
