I am exploring the use of cisco routers on a network which includes
both x25 and ethernet (ethertalk, TCP/IP, Novell.)  What I am
wondering is what is the most efficient routing method for this kind
of network?  X.25 or tcp/ip?  Below is a simplified example for the
proposed network.  Notice that all serial links are between ciscos.

 [x25 PAD]--+ cisco +----serial-------        [other data centers]
            +--+----+                 \		      |
               |                       \	      |
    <--o-------o------o--->             \	      |
       |              |                  \         +--+----+ data center
    +--+---+       +--+---+               ---------+       |  +--+---+
