Static Route - Unable to add to router

[MarquezHB00]

Hello,

I have 3 routers connected on which I ran IP OSPF 1 Area 0 command and they all worked fine as I am able to ping from each computer connected to the router through a Switch. 

I decided to removed OSPF from all interfaces using NO IP OSPF command and proceeded to set static route on each individual router by stating what LAN to reach out of a given interface ex. ip route 192.168.10.0 255.255.255.0 Gi0/0

I am only able to set static route on 2 of the routers which allows me to ping one LAN to the other but when I proceed to add a new static route 2 of the 3 routers will go through the process but when I go to see the static route they are not shown nor can I ping one LAN to the other as I expect after adding the new Static Route.

Some help on why this can be?

Ps. I have started a new equal topology on which I added the static routes to the 3 routers and they work fine.

perhaps u made a typo when typing the command Or command was not accepted because it  was not correct; router should give u message, didn't it?

OSPF does not have anything to do with manually adding static routes -even if u do not remove ospf configs. find table with default ADs for protocols, Static routes AD is 1 where as  OSPF default is 110. lower one is preferred so router would choose static route anyway (there are some restriction or dependencies)

Hi Martin,

I did receive the message that states "Default route without gateway, if not point-to-point interface, may impact performance"

I do receive the same message when I set static route on any other router and then I am able to see the static route on routing table but in this case I do not see it.

I even tried resenting the entire interface by running default interface command on it but nothing.

Thanks for your reply

I forgot to mention I am using Packet Tracer latest version

Hello,

post the Packet Tracer project file (.pkt) as a zipped file...

I thought so;  PT has bugs for some advanced stuff (or not bug but some advanced stuff is simplified)

see https://www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/8651-21.html

you must know the order which is 1. prefix length (aka mask or /), 2. AD, 3. Metric

Guys, 

I just found out after typing "show ip interfaces" that the interfaces I am having trouble with on those routers read "Internet Protocol Processing Disable"

I will have to enable them back on I am pretty sure!

that is when you do not have IP address assigned to interface;  u will see "Internet Protocol Processing Disable"
