Greetings Eric
On a router (lets call it router A) , if you have seperate OSPF processes;
lets say process 1 and process 2
They will NOT be mixed on router A. Router A will have two seperate OSPF
tables. When you do a show ip route you should see both but I suspect the
routes from process 1 will have a 1 in front of them somewhere and the ones
from process 2 will have a 2 in front of them somewhere.
You were correct in saying that the only way to get the routes from process
1 into process 2 (or vice versa) is to redistribute them.
Keep in mind though that that separation only happens on router A
lets say router A has three interfaces s1 s2 s3
s1 is connected to router B
s2 is connected to router C
s3 is connected to router D
s1 is listed in its network statement (on router A) under process 1
s2 and s3 are listed under process 2.
Usually when you have multiple processes its for a reason, your intent is
to somehow segregate your network.
Lets say Routers B and C are also running process 2
If you were to accidentally hook router A s1 to the router B or C
connection you would then effectively mix the routes from the 2 processes.
Advertisements pay no attention to the process number. All they care about
is if you're a neighbor and your password is correct (and your timer values
are the same).
hope that helps
Tom
