I’m working on a test lab with a couple Cisco 2503 routers with BRI interfaces, as well as a Teltone ISDN simulator, and a couple ISDN “modems”.
I’ve entered several static routes to networks on the “other side” of the ISDN network.
As long as the static routes is something like this:
ip route 172.16.241.1 255.255.255.0 bri0
it works okay. Note that 172.16.241.1 is the address for the “other side’s” bri0 interface (172.16.243.1 being on “my side”).
However, if I REMOVE that route, and try to enter any other static route at all—regardless of source or destination used—it fails.
According to documentation, I should be able to do something like
ip route 192.168.1.0 255.255.255.0 172.16.241.1
And that should work because of my dialer map statement, which maps 172.16.241.1 to the router on the other side.
I can’t figure why it works with the one static route entry (and then I can add, and reach, any other networks on the other side by adding statics for them, as well), but it won’t work, or accept any static route entries, if I don’t add that one line.
Any ideas from anyone?
Thanks in advance.
