[c-nsp] NSF aware OSPF

[Volodymyr Yakovenko]

Hello!

 According to SSO/NSF documentation in case of OSPF usage neighboring routers
 should be "NSF-aware". 

 It looks like that for some equipment (like Cisco Catalyst 3550) IOS with 
 NSF-awareness functionality will not be ever available. It looks like there 
 is no any General Deployment NSF-aware IOS available.

 In case of ISIS there is 'Cisco configuration option' which brakes "all 
 routers in subnet should ne NSF-aware for NSF switchover" rule.

 Does anyone know will such "Cisco" mode be available for OSPF or not?
 Is there any technical reasons why it could not be implemented?
