      Our mailer tries to deliver mail to (,
      SILVACO.BARRNET.NET) and gets host unreachable. Routes for ar
      given as:
      gw3#sh ip ro
      Routing entry for (mask, 2 known subnets
        Redistributing via igrp 51771
      B [200/100] via, 16:10:55
      B [200/100] via, 16:11:51
  This is odd. You should have a route to which handles
  all subnets of 131.119.

Did you turn off auto-summary, or did you add explicit network commands?
If you turned off auto-summary, you'll no longer generate a 131.119/16

FYI, this is just a general warning to everyone... no auto-summary does
what you tell it to do. :-)  (Vince, let's take this private and we can
work out what went wrong...just in case.)
      Is it useful to add Class-B-Subnets to the routing table whilst we are
      trying to reduce Class-C entries?
  This was an oversight. We are sending the subnet routes to ENSS128 in order
  to insure correct next-hop resolution across our DMZ network. These subnets
  should not have been sent to other external peers and no longer will be.

  P.S. In the future, you will receive faster response if you send BARRNet
       problem reports directly to us, either to "noc at BARRNET.NET" or to the
       MERIT-maintained trouble list "as200-trouble at MERIT.EDU".
