I'm looking for ideas on how to have complete HA between a dedicated T1 and an L2L VPN over the internet.
We had discussed routing protocol OSPF but would like to avoid the converge issues that could rise and affect other customers in the same DMZ.
What would be our options if we do not want to use a routing protocol? How could we fail over to the backup line, the L2L, should the T1 fail. I had mentioned changing the metrics but this will not identify a problem on the line should the customers ethernet link goe down.
Feel free to include an ideas that would use routing protocols.
