Hello all,The primary connections to our remote routers are point-to-point frame relay circuits. We have ISDN connections that will act as a backup, in case the primary fails. My question is, what is the best backup method when there is no dynamic ro...
Hello all,We have a 1721 at a remote location, and a 2821 at our local site. We are trying to get the remote site to call in and connect to our local site via ISDN. The 1721 has a BRI interface. The 1821 has a PRI interface. The 1721 ISDN connection ...
Hello all,We have a VWIC-1MFT-T1 on a 2821, and have a ISDN PRI circuit. The purpose for this circuit is a failover for remote locations in case their primary link goes down. I was told this VWIC card will work for what we need. Unfortunately, I have...
Hello all,We are putting together an ISDN solution between our central site and remote locations. We currently have a number of 1841s with ISDN BRI WIC cards installed and ready to go at our remote sites. We have a 2821 at our central location that i...
Here is my scenario...I have two servers that are both connected to a single 3560 (SMI). These two servers are in a primary/secondary relationship. Right now, if the primary server goes down - we need to manually configure the secondary server to tak...
Ok, I got it to work now. When I simulated the outage of the primary link, my local router's serial interface was still reporting up/up. That is why it kept the primary route in the routing table. I didnt post the configs because it wasnt a configura...
Thanks Victor,I tested out this theory in my lab, and it did not work. The remote router (the one with the backup interface configured) actually added the floating static route in its routing table when I disconnected the primary circuit and the seco...
Victor,I understand what you are saying. I perfectly understand the concept of dynamic routing and floating static routes. I clearly understand how to use AD. I do not think you fully understand what I am asking here. Please throw dynamic routing out...
Ok, I still need clarification on this. How do I use my ISDN connection as a backup when I am only doing static routing? It seems to me that backup interfaces, dialer watch, and floating static routes only work when you have some sort of dynamic rout...
Thanks, I was not really worried about PPP right now - because like you said it is not even getting to that point.Satish, your config suggestions make sense... but you think I should remove the SPIDS on the remote router BRI0 interface?I am going to ...
