I'm a bit new here, and I'm not quite sure where to post this. I have a 7206vxr router, and a lot of catalyst switches. I have a management net consisting of 64 addresses. 90.xxx.85.0/255.255.255.192. It's routed to the internet as well. (through the 7206) My problem is the 7206 router. I've made a loopback interface with the IP of 90.xxx.85.20 with a subnet mask of 255.255.255.255. when i run no shut on interface loopback0, I can't get hold of anything on the outside of the 7206 (e.g. The Internet).
no fancy configuration on the loopback, just this:
ip address 90.xxx.85.20 255.255.255.255
This is of course, an available ip address in my range.
The only extra route info on this subnet (except the default route) is this line:
ip route 90.xxx.85.0 255.255.255.192 90.xxx.90.2
90.2 is a pix.
Anyone with a clue to what happens when i activate the subinterface loopback0?
