I have a scenario of setting up a network for customer.
On the customer end, we have a 2621 connected to a 2503 (we name this as PRI router) on our side with a 1Mb leased line. On event in case the leased line is down, we have 2 128k ISDN line as a backup. Now the problem is, how do I configure in a way that from 2621 (with a 4 port BRI module) connected 2 ISDN line to PRI router and to the another same model router. Both 2503 router is connected to a 1500 series switch.
What can I do to make both 2503 router connected to 2621 router to run both at the same time, when is backup is activatied.
Thnks,
Regards,
