My Multinet link to area 59 is down, but LEGATO thinks area 59 is accessible thru CEIRE, which thinks that it's accessible thru A54RTR. The latter box apparently doesn't speak NML (or won't talk to me) so I can't ask it what's going on. Peter??? Are you out there?? Is area 59 up or down??? And what's A54RTR? Hi Bob, At least one of the Peters involved is here :-) A54RTR is a Cisco IGS which has GRE tunnels to area 59 on test. It appears the more standard connection from area 59 to the rest of Hecnet (via SG1 perhaps?) is down. A similar thing is going on with area 52 (CEIRE -> A54RTR -> ???) although I don't have a Multinet link in this instance. Are there any machines in area 52 actually up? Area 52 appears to be reachable via area 59. It looks likely that area 52 should also be reachable via SG1 but isn't. The router(s) in area 52 and 59 don't appear to speak (much) NML either.

At this moment I can't see anything from area 7. I guess John has just turned off his side.

LEGATO thinks area 7 is routable via the Multinet link to GORVAX, and GORVAX thinks area 7 is routed via the Multinet link to SG1, which thinks area 7 is adjacent via the Multinet link to GORVAX.

SG1 does appear to bounce up and down fairly often. This is an old problem that was discussed but never really resolved. Since SG1 is an area routing node, having it bounce undoubtedly confuses things. Bob Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES

Area 7 and 8 funny...?

More if you know that BITXT2 is a KLH-10 machine running inside a VBox machine running in the same host as BITXOO (the node from which I executed the command). To be honest, I have absolutely no clue about what's going on. At the same time the CPU usage of the host machine skyrocketed to 200% (100% of both cores). To add to the weidnesness, I run a java applications server (glassfish) there, and it was over 90% of CPU... when it should be idle. I guess I need to do a preventive IPL of that machine.

"Poor mans routing" and the Italian Hobbyist DECNET

I've downloaded it and had a look through it. Let's assume the most usual conflict is at hand, where two different ogranisations use area 1, but neither the networks nor the areas can be merged, but the organisations need to communicate using DECnet. Organisation A applies in the router the DECnet map for Organisation B where the B's real area 1 is chosen to have a virtual area of 24 (which is not used in either networks). Then B assignes a virtual area of 25 to the A's real area 1. Then they configure their routers to use DECnet map and the result looks like: A Cisco ATG B 1.1 -----------------> 24.1 --------------------------------> 1.1 1.2 -----------------> 24.2 --------------------------------> 1.2 1.3 -----------------> 24.3 --------------------------------> 1.3 1.4 -----------------> 24.4 --------------------------------> 1.4 And in the opposite direction it looks like: A 1.1 <------------------ 25.1 <-------------------------------- 1.1 1.2 <------------------ 25.2 <-------------------------------- 1.2 1.3 <------------------ 25.3 <-------------------------------- 1.3 1.4 <------------------ 25.4 <-------------------------------- 1.4 If there aren't any other conflicting areas, all other areas can be routed normally. That seems straightforward enough. I could set up a test with you. Thanks. However... The commands available seem to suggest an individual mapping is required for every host. Is it also possible to map a whole area with a single mapping? It didn't use to be, but the manual says it should be possible on some release 12's but not all. My poor old IGS has version 10.0(6) so it doesn't appear I would be able to map whole areas. The manual seems to say that no communication is possible between the two networks unless mapping entries exist for each of the hosts that want to communicate. This suggests I would need a mapping entry for every host on HECnet and every host on the other network. I think that would probably be too difficult to maintain and might not even fit in the NVRAM. Maybe someone with a later version of IOS might like to try? Regards, Peter Coghlan. I could definitely give this a go. I'm running latest 12.4 on my 1841. -brian . Please check your IOS if the Decnet map command is still included. Some Cisco document claimed that it has been removed from the latest versions. Regards, Kari
