I can imagine, but I don't think that will be a problem in this case.  
Each database server should never consider that it has any other IP  
address except one in particular. The single IP addresses that they  
each use to reach their remote companions will never change either.  
Only the routing in between will occasionally change as needed when  
the main links go down and up.
