Metro Ethernet Failover Problem

Unanswered Question
Mar 1st, 2007

I have a problem that I am working on and wondering if somebody can help me out. We have dual 10 Mbps TLS circuits from our facility to another Regional office. I have configured floating static routes for the metro E; however, the problem with this is that if the metro E drops somewhere in our path, the routers won't both detect a drop in the circuit because they still have a connection to the next hop device. Therefore, the routers never install the floating route. Is there anyway around this?

I have this problem too.

can you ping your gateway?? is it working fine or not?

If it is working fine with no drops mean you lan connectivity fine.

After trace remote destination and take output.

In output what are the hops show by trace command... ping in different windows all are that IP addresses. and Observe some time.

You will look , on which ip address packets are getting drops.

If on perticular router can be examine... than look out on that router or if you are not administrator of that router than tell to that guy who has control.

In this case the best way is to put a GRE tunnel so that any segment between two sties is down, GRE tunnel will go down

The other way out is to run any dynamic routing protocol. In ur case, as i presume, there are small number of network devices, the best way is to run RIP on all the available links towards a particular destination.
