I have a simple network I've scanned in and am now mapping. See below.
I understand the why behind the red dashed line and have been and upvoted https://thwack.solarwinds.com/ideas/3827 already. However I'm confused by my result. On the left hand side are 2 ISP routers (same ISP) and we have read-only SNMP access to both routers and discovery picked up the correct interface that we physically connect to.
So question: Why is the primary router link showing a dashe dline but the secondary a full link and can dispaly utilisation or link speed?
