[c-nsp] OSPF Route Distribution

[Yuri Selivanov]

	Hi.

	I would use *MAY* verb here: the 'network' statement under ospf
provides a control over which interfaces will run ospf. It doesn't
deal with prefix advertisement as 'network' statement under bgp does --
these protocols have different 'network' concepts. 

	So it's possible to use:

 network 0.0.0.0 255.255.255.255 area 2 ! all ifaces will run ospf
 network 10.0.0.0 0.255.255.255 area 2  ! only 10.x.x.x ifaces 
 network 10.10.10.0 0.0.0.255 area 2    ! only 10.10.10.x ifaces 
 network 10.10.10.2 0.0.0.0 area 2      ! only iface with 10.10.10.2
