[HECnet] Hecnet Peering

[Mark Darvill]

Tim,

Just discovered the ping decnet command in IOS   

Can ping you 12.1023 and 12.2 from the router which is good; can ping 22.10 from the router which is also good; but for some reason i cannot connect from VAX (22.10) on FastEthernet0/1 to 12.2.

This must be a local issue.

Is there anything else I need to setup above what I have for FE0/1 and decnet on my router?

decnet routing 22.100
decnet node-type area

interface FastEthernet0/1
  ip address 10.22.1.254 255.255.255.0
  speed auto
  full-duplex
  lat enabled
  decnet cost 4

and my tunnel to you which I don   t think is the problem

interface Tunnel57
  description HECnet tunnel for Tim Sneddon (Area 12) [Version:274]
  no ip address
  decnet cost 20
  tunnel source FastEthernet0/1
  tunnel destination 120.146.225.243
  tunnel path-mtu-discovery

Hi Tim,

DECnet on this test system is just Decnet IV running on VMS 7.3.

I can   t do a loop node to 12.1023 but not sure that would work anyway if it is a cisco.

Also can   t seem to get to 12.2. Have just rebooted 22.10 as SIMH may have crashed.

HI,

I have been playing with my cisco router and a SIMH Vax over the break.

from my router I can see the following neighbours

cmrtr01#show decnet nei

My SIMH Vax can see my router and has an adjacency. My node is 22.10 and router 22.100

Can anyone see area 22 as I don   t seem to be able to communicate elsewhere.

Hi Mark,

My network is 12, your Tunnel57 hooks into my router.   From my router I am able to ping 22.100, but I cannot reach 22.10. Are you able to hit my router (12.1023) or my VAX (12.2)?   Which version of DECnet are you running on 22.10?

I am happy to help you figure out what might be going on.

Regards, Tim.
