[HECnet] Why does MIM not list 23.1023 as a known node?

Ah ok. So it’s not a blind dump of routing tables received from other routers, but actual traffic generators, and defined node names.

Thanks.

Both 31.1 and 31.1023 are L2; and 31.1 is connected to MIM via MULTINET. 23.1023 does not show as known to MIM either. But MIM and 31.1 do know about area 23 nodes  piglet, owl, rabbit etc.
