Problems with BARRNET network 131.119.250.119

    Our mailer tries to deliver mail to 131.119.250.119 (bargate.silvaco.com,
    SILVACO.BARRNET.NET) and gets host unreachable. Routes for 131.119.0.0 are 
    given as:

    gw3#sh ip ro 131.119.0.0
    Routing entry for 131.119.0.0 (mask 255.255.255.0), 2 known subnets
      Redistributing via igrp 51771

    B       131.119.246.0 [200/100] via 193.23.5.33, 16:10:55
    B       131.119.253.0 [200/100] via 193.23.5.33, 16:11:51

This is odd. You should have a route to 131.119.0.0/255.255.0.0 which handles
all subnets of 131.119.

    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".
