Hi there

can you suggest a good HA solution based on freeBSD servers, like the
following.
Load balancing TCP+UDP on virtual ip + failover on the routers.


                       ( net )
                         
                          |
                          |
                          |
                      ----------
                     |  switch  |
                      ---------- 
                      /        \
                     /          \
             ----------      ---------- failover
            |  active          backup    
               router  |    |  router  | 
             ----------      ----------
       load-balance \          / 
                     \   VIP  /
                     ----------
                    |  switch  |
                     ----------
                      /      \ 
                     /        \
              ----------     ----------
             | server1  |   | server2  |
              ----------     ----------
                     real servers
