Hello to all.
Are there certain versions of IOS that does / does not need the clearing of the OSPF process for the hard coded RID to take effect? I have not yet tested this on real gear and I'm using GNS3 at the moment. I had a discussion about this in another forum but we have not concluded anything yet.
Below are my outputs from GNS3.
R1(config-router)#do sh ip prot
Routing Protocol is "ospf 1"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Router ID 192.168.1.1
R1(config-router)#router-id 1.1.1.1
Reload or use "clear ip ospf process" command, for this to take effect
R1(config-router)#do sh ip prot
Routing Protocol is "ospf 1"
Outgoing update filter list for all interfaces is not set
Incoming update filter list for all interfaces is not set
Router ID 192.168.1.1
R1(config-router)#do sh ver | i IOS

The following are the results tested by another member I was having the discussion with. He was using real gear.

I'm currently searching for official documentation about not needing to clear the process upon hard coding the RID but couldn't find one. Thanks in advance.
