Hi there!
Here's a question on routing.
I've got 25 class C addresses for use within our campus. So far we've been using
just one class C range to serve our site, but expansion has forced us to
collapse our Ethernet backbone and get the other class C ranges in to action.
We're using a cisco router to connect to the Internet. And a Gandalf VLS to
house our internal routers. The VLS contains multiple routers within one
cabinet.
            +---------+
            | Router  |
Internet ---| x.x.1.1 |
            +---------+
                 |       +------------+
                 |       | nameserver |
                 +-------|  x.x.1.2   |
                 |       +------------+
                 |       +------------+
                 |       |    host    |
                 +-------|  x.x.1.3   |
                 |       +------------+
                 |       +------------+               +-----------+
                 |       | VLS        |               | PC1       |
                 |       |============|       +-------| x.x.2.254 |
                 +-------|  x.x.1.10  |       |       +-----------+
                         |============|       |
                         |  x.x.2.1   |-------+       +-----------+
                         +------------+       |       | PC2       |
                                              +-------| x.x.2.253 |
                                                      +-----------+
Here is netstat -r on nameserver x.x.1.2:
 Routing tables
 Destination      Gateway            Flags     Refs     Use  Interface
 Netmasks:
 Inet             255.255.0.0
 Inet             255.255.255.0
  
 Route Tree for Protocol Family 2:
 default          x.x.1.1            UG          1    74790  tu0
 localhost        localhost          UH          3   275692  lo0
 x.x.1            x.x.1.2            U          17  2495758  tu0
 x.x.2            x.x.2.1            UG          2    18726  tu0
So far:
 -PC1 can ping PC2 as expected (0 ms)
 -PC1 pings nameserver x.x.1.2 immediately (0 ms)
 -PC1 telnets nameserver x.x.1.2 in 1 minute 20 seconds! (why?)
 -PC1 cannot ping, telnet, or traceroute to the Internet
 -nameserver x.x.1.2 can ping PC1 immediately (0 ms)
 -nameserver x.x.1.2 cannot succesfully traceroute PC1:
  % traceroute x.x.2.254
  traceroute to x.x.2.254 (x.x.2.254), 30 hops max, 38 byte packets
   1  x.x.1.10 (x.x.1.10)  10 ms  0 ms  0 ms
   2  * * *
   3  * * * and timeouts thereafter
I've got plenty of VLS help available. I need some information on how routing
should be set up on the nameserver (x.x.1.2), an OSF/1 v3.0 alpha.
