[c-nsp] OSPFv3 Adjacency issues between 2921 and 3750

[Peter Subnovic]

Hi Pete,

thanks for your time.

The 3750 does not respond when i try to ping ff02::5. It does however
respond to the all-nodes/all-router ll Multicast address.

The authentication configuration is only for ospfv2. So i think it will not
make any difference.I cant try it without right now.

Thanks,
Peter
