Brian H is working on the CISCO stuff and maybe the bridge users could provide some meta-info about their connections say in a BRIDGE.INFO file or something? sampsa On 12 Jan 2013, at 17:21, Johnny Billquist <bqt at softjar.se> wrote: On 2013-01-12 16:10, Peter Lothberg wrote: If you ask me, I think this idea is dead. You cannot get a good representation of how the topology really is from trying to walk nodes using NCP. (remove bridged ethernet that are not point-to-point with only 2 nodes). Walk through the "known cir" and then "cir char" and build your own connectivity tree with the metrics. Plot all links Apply DECnet routing rules and Colour the links that carry traffic with the current metrics and/up/down condition, use two colours, one for transmitt one for receive (as links can end up being simplex). Well, it all depends on what you want to know. If you want to properly understand the topology you also want to represent the topology of bridged ethernet segments, as well as ethernets in general. NCP don't have any clue about this. Sure, if you want to only have Multinet ptp links, then it's easy. But that would a rather severe restriction on the network technology. We have ethernets (both bridged and local), as well as Cisco tunnels. Both of which walking with NCP fails on.
