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
