-I have this route that is causing some hellish issues. This one route with IP 220.127.116.11/32 needs to be removed but I can not seem to figure out how. I know its a route learned through OSPF. Anyone trying to his this particular address is being redirect to 172.20.2.2 which is our backbone to our building accross the street. This address should be going straight through our firewall. Any suggestions please. I tried the following in configT mode...
ip route 18.104.22.168 255.255.255.0 172.20.100.251 ?
After 172.20.20.100.251 its asking for a distance metric. I do not what to do beyond this point??????
Not sure if you're familiar with Administrative Distances.
Administrative Distances are used as a "weight" when a router learns multiple paths to the same destination via different means (static route, OSPF, EIGRP, etc...). Cisco has a default AD for each routing protocol (including static and connected routes) based ostensibly on the "believability" of that protocol to provide the "best" route. The default for OSPF is 110.
The default for a static route is 1 (it is assumed the admin knows what he/she is doing). You can specify another AD, but that is optional. So if you enter the command as you have without the ? you will install the static route in the table. (Higher ADs for static routes can be useful for "floating static routes", for example.)
The router will treat routes to the same network but with different masks as different routes. Note that (higher) specificity wins by default in routing decisions.
My preference, however, would be to find out how/why the route is coming in via OSPF, and if that is expected behavior. Do you have the static route installed in another router, and being redistributed via OSPF, by chance?

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
I couldn't connect to the hos...
