If I have a router with 4 interface
int1 connect to the OSPF network / backbone
and int 2,3,4 are vlans with no other routers attached
int1 has network 10.10.1.0/24
int2 has network 10.10.2.0/24
int3 has network 10.10.3.0/24
int4 has network 10.10.4.0/24
If I want the network
distributed by OSPF, I can add in the interfaces int2-4 and then make them
passive as there is no OSPF there.
Just realised I can also redistribute the prefixes as NSSA-ext1 or 2.
Whats the difference , which is considered to be best practices, I have
also setup interfaces with passive OSPF.
