Hello All, I am facing a very typical problem. The test set-up includes 2 sites. There are 2 simultaneous links (one of 64Kbps Leased Line and the other of 32Kbps VSAT Link) between the 2 sites. What I want to achieve is that my application (which is real-time) should go on the 64K link while rest all traffic (like mails and intranet) should go on the 32Kbps link. When any of the link is down, then the affected traffic shud switch to the other link with higher priority to the application. I have defined access-lists and route-map policies accordingly. I have applied the policy on the LAN port of the router. Also, the serial ports are IP Unumbered. I am facing the problem only when the Leased Line is down and the traffic has to shift to VSAT.
I have configured EIGRP on the routers. When I do a debug, it clearly shows me the traffic is going according to the policy map. When I give a loop on the LL modem at one end, the line protocol as well as the serial port goes down. On the other router, the serial port shows me looped, the line protocol is down but the serial port is (as all the EIA signals are up). When I see the IP Route to the destination, there is only one route thru the VSAT link. Now because of this serial port up, the far-end router still pushes the packets to this serial port (as it sees that it is up) but end to end connectivity is not thru cos the line protocol is down. When I manually shut down the port, then the packet starts going thru the alternate route and end to end connectivity is through. As soon as I remove the shutdown, the connectivity is lost again. Now what is bugging me is that I have tested the same setup at one more location and it works absolutely fine there be it switchover from Leased Line to VSAt or vice-versa. When the Leased Line modem is given a loop, the serial as well as line protocol is down. The far end serial port is looped, line protocol is down & serial port is up (all EIA signals are up). Even then the traffic shifts to VSAT and the connectivity still exists. I checked the configuration of both the set-ups line by line but no use. The only difference in the 2 set-ups is that the problematic one is on CISCO 2600 series while the working one is on 2500 series router. I am attaching the config as well as the version of the 2 different series router. I am really in a fix as to what to do next. Please help me out.
