Maybe a better way of asking this question is if I use link load balancing and one of the links fail would the remaining link continue to function normally without interruption to service. The second question is concerning the differences in link speeds will it degrade performance in comparison to only using the high speed link? Looking through the HOWTO and searching the archives I have not found the "what if" answers.

The T1 Link is a backup. My questions are the following: If I do a split access between the VPN and T1 links giving weight of a 1 to the VPN and a weight of 2 to the T1 link and I should loose either connection am I correct to say that I will still suffer loss of connections. I am assuming that the weighting option being round robin is not ideal for redundant setups. Is it primarily for load balancing? Am I wrong here? Second question, would it be a better solution to tie the links together for load sharing as chapter 10 states in the Adv-Routing-HOWTO? My problem is not load, but routing for unlike redundant lines. I could care less if anything goes across the T1 link unless the VPN link goes down. The idea is to have the Linux boxes eliminate manual re-routing in the event of a link failure. Maybe I have missed the ideal setup altogether. Any point in the right direction would be a great help.
