Hello all, I have a 6509 with sup 720's. I have a vendor that wants to remove their router and go with a lan to lan VPN. The problem is I disconnect the router which goes to my 6509 and I need to change the route from the directly connected device to point to the firewall. I unplugged the router for a hour and when I do a "sh IP route" it still show 220.127.116.11 is directly connected, null0. Not sure if I can issue a "no ip route 18.104.22.168, null0"
It seems to me that we need to know a bit more about this situation. What is the subnet/network that the vendor was using? Was it 22.214.171.124/16 or was it some part of that range? Is there any other part of that address range that you need to access?
That kind of route x.x.x.x connected to null0 is sometimes the result of a configured summary address. Or it might be a static route configured that way (I see this with some frequency in the configuration of BGP routers) so that the route is always in the routing table. If you could cut and paste that line out of show ip route and post the output we might understand a bit better how it got there.
You mention that a router for the vendor was removed. Was that router running a dynamic routing protocol with your switch? Or were routes statically configured?
If we understood the situation better we could give better advice.
The vendor has PCs and printers on the 126.96.36.199 that connect to our AS400. They state they need that entire range. I swore when I looked yesterday it had a C, now when I look it has a S, so it is static route.
Yes that does indicate that it is a static route. You should be able to remove it without much problem and then if you want to configure a new static route which points that network toward your firewall it should be easy to do so.
You could use the complete line including the mask and the null0. Or you could use the address and the mask and it would work. If you try with only no ip route 188.8.131.52 you get an error indicating incomplete command.
