Topology view confused with router sub-interfaces

[ggolding]

Installed a demo of LMS 2.5 for client and found that Topology Services acts a bit strange when routers are using sub-interfaces.

The Layer2 view will show the connection between the switch and the router, as well as a phantom link from the router to nowhere.

The Layer 3 view will corectly show all the switches and other devices in a group as connected except the router.

This only occurs when the router is using ethernet sub-interfaces.

Any idea's why this happens?

Network Views displays the following:

LAN Edge ViewDisplays hierarchical network view of network connectivity at Layer 3, all devices that have routing characteristics are displayed. Devices without Layer 3 connectivity are placed in a sub-view.

Layer 2 ViewDisplays the Layer 2 information about your network, including ATM and LAN switches, routers, MLS devices, hubs, and switch probes.

VTP ViewsDisplays devices that are participating in VLANs, including LANE components.

Unconnected Devices ViewDisplays devices for which connectivity information could not be obtained, including devices which are not supported by Topology Services.
