So I'm not sure if this involves a nuance in Packet Tracer or if there's something I'm doing wrong -- one thing is for certain, though I don't yet totally understand the network command although I will have a question on that later. I want the neighbor relationship/adjacency to FAIL but oftentimes it simply doesn't, and I also want to make sure the deleted network doesn't show up when I run "show ip ospf interface"
I didn't think this question involved needing me to post my topology so I'll try to describe and ask my question without it.
So I have a fully OSPF network (1941 Routers):
PC1 ------------------- R1 ----------------- R2 ---------------- PC2
(10.0.0.1/24) (10.0.0.2/24)/ (20.0.0.2/24)/ (30.0.0.2/24)
(20.0.0.1/24) (30.0.0.1/24)
Everything is in Area 0 and all are 1941 Routers.
The way I set the Routers:
R1:
> router ospf 1
> network 10.0.0.2 0.0.0.255 area 0
> network 20.0.0.1 0.0.0.255 area 0
R2:
> router ospf 1
> network 20.0.0.2 0.0.0.255 area 0
> network 30.0.0.1 0.0.0.255 area 0
On R1 the adjacency successfully forms BUT when i try to make the adjacency Fail, I have a problem
To make it fail I try:
R1:
> no network 20.0.0.1 0.0.0.255 area 0
> end
> clear ip ospf process
But when I do this it usually simply reconverges and the adjacency is reestablished and the interface/network still shows as "area 0" when I run "show ip ospf interface".
I say USUALLY because there was once where I did it over and again, exclusively on R1 but used the commands:
R1
> no network 20.0.0.1 0.0.0.255 area 0
> no network 20.0.0.2 0.0.0.255 area 0
> end
> clear ip ospf process
And it worked after a while, but I was wondering "Why?" But more importantly why when running the initial commads, those didn't prevent the adjacency or remove the network from the area?
