[c-nsp] OSPF question

[Paul Wells]

Hi Robert,

Everything Darren says is correct. However, in your example below you 
also removed:

  ipv6 ospf 12345 area 0

You will still need to enable OSPFv3 (ipv6 ospf) under the interface in 
12.2(33)SXJ. OSPFv3 doesn't have a "network" command.

For a more comprehensive list of which releases support the OSPFv2 
interface enable command you can use feature navigator. Search for the 
following feature names:

Area Command in Interface Mode for OSPFv2
Enabling OSPFv2 on an Interface Using the ip ospf area Command

Note: both names refer to the same feature, though in different trains. 
The command is available on the cat6k starting with 15.0(SY).

Regards,
Paul

You don't need both the interface config and the process config. It doesn't break anything using both, but it makes it difficult for others to troubleshoot later. If you did use both, the most specific will 'win'
