- The Novell gurus here have asked my help with our first attempt at IP routing
- thru 3.11 servers. The application is a few macintoshes which will run
- NCSA TELNET to get to our VAX.

- & Multinet 8.2(7) 3.11
-
- PC's sitting beside the Mac can see the VAX on SLIST.
-
- I read the FM and set eveything up as (I think) it says.
- Both the VAX net and the campus backbone are set for Ethernet II packet types.
- TCPCON sees packets arriving every few seconds.
- The cisco ARP cache has a correct entry for 161.28.1.64 .
- BUT -- no traffic flow. The cisco can't even get a "ping" echo from the
- server.

- Done. Mac says gateway is 161.28.64.254

-
- Cisco is set "route rip"

-
- OK there subnets and masks are set on both Novell interfaces
- -----------
-
- Still the server will not answer a PING.
-
- So:
- Q1: Is a healthy 3.11 IP router supposed to PING?
-
- Q2: If so, what can stop it?
-
- Q3: (more advanced) Do I need to worry about re-distributing the RIP
- derived routing info out to westnet?
