Multiple Servers have wrong "IP Connection::IP connection" with Routers/Switches that are not directly connectedIssue <!-- div.margin{ padding: 10px 40px 40px 30px; } table.tocTable{ border: 1px solid; border-color:#E0E0E0; background-color: rgb(245, 245, 245); padding-top: .6em; padding-bottom: .6em; padding-left: .9em; padding-right: .6em; } table.noteTable{ border:1px solid; border-color:#E0E0E0; background-color: rgb(245, 245, 245); width: 100%; border-spacing:2; } table.internaltable { white-space:nowrap; text-align:left; border-width: 1px; border-collapse: collapse; font-size:14px; width: 85%; } table.internaltable th { border-width: 1px; padding: 5px; border-style: solid; border-color: rgb(245, 245, 245); background-color: rgb(245, 245, 245); } table.internaltable td { border-width: 1px; padding: 5px; border-style: solid; border-color: #E0E0E0; color: #000000; } .title { color: #D1232B; font-weight:normal; font-size:28px; } h1{ color: #D1232B; font-weight:normal; font-size:21px; margin-bottom:-5px } h2{ color: #646464; font-weight:bold; font-size:18px; } h3{ color: #000000; font-weight:BOLD; font-size:16px; text-decoration:underline; } h4{ color: #646464; font-weight:BOLD; font-size:15px; text-decoration:; } h5{ color: #000000; font-weight:BOLD; font-size:13px; text-decoration:; } h6{ color: #000000; font-weight:BOLD; font-size:14px; text-decoration:; } ul{ list-style: disc outside none; margin-left: 0; } li { padding-left: 1em; } --> Servers from one region are showing IP connection::IP connection with multiple different switches and routers that do not seem to be valid. One server has IP Connection :: IP connection relationship with more than 100 routers.Most of these routers are located in a different region when compared to servers CauseIf you look at the SNMP-Routing input, You can see the following input from the switch. From this we create a router interface with dest_ip_network as 10.0.0.0/8 <ipRouteEntry instance=".10.0.0.0"> <ipRouteIfIndex type="SnmpInt32">76</ipRouteIfIndex> <ipRouteDest type="SnmpIPAddress">10.0.0.0</ipRouteDest> <ipRouteMask type="SnmpIPAddress">255.0.0.0</ipRouteMask> <ipRouteNextHop type="SnmpIPAddress">0.0.0.0</ipRouteNextHop> <ipRouteType type="SnmpInt32">3</ipRouteType> </ipRouteEntry> -when discovery completes it will generate a discovery device complete event. Then, that event will trigger a script action, which will call the script include, which is the "L3 Mapping script". In that logic, it will search the dscy_route_interface table for hi_ip and lo_ip. -So, if you are scanning any computers or servers that fall within these ranges, you will get these "IP connection::IP connection" relationships created between those devices to this switch accordingly. -In some cases, this may be a valid route on the switch because of the configuration of the switch. You can ignore this by making some modifications to L3 Mapping script include.ResolutionIf you would like to ignore this dest_ip_network, please add the following line in L3 Mapping script include to ignore the dest_ip_network 10.0.0.0/8 as it will have huge range(10.0.0.1-10.255.255.255). As said above, if you are scanning any server which is in range (10.0.0.1-10.255.255.255), it will create a IP connection::IP connection with the router. Please add the following to ignore this dest_ip_network after below line (around 98): var gr = new GlideRecord("dscy_route_interface"); add: gr.addQuery("dest_ip_network","!=","10.0.0.0/8"); Please note, there may be other dscy_route_interface records that are causing the connection to be created. If adding the above query to exclude route "10.0.0.0/8" does not resolve the issue, check the dscy_route_interface table for other matching networks - or alternatively view the dscy_route_interface records for one of the routers that continues to have the relationships created. If you are able to confirm that another large network is defined in the dscy_route_interface table, add it as another query similar the above, making sure that the query exactly matches the "dest_ip_network" field of the dscy_route_interface table. To provide an example - if there were to be a dscy_route_interface for a router with dest_ip_network "169.0.0.0/8", you could add the following query at the same position as the above mentioned query: gr.addQuery("dest_ip_network","!=","169.0.0.0/8"); Further troubleshooting information can be found in the following Knowledge Article: https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0598422
