The following routing-device types are supported by the IP Manager:
Route switch modules (RSMs)
Route switch feature cards (RSFCs)
Multilayer switch feature cards (MSFCs)
Virtual routers are implemented within physical routers or switches.
RSMs, RSFCs, and MSFCs are routing-device type cards in Layer 3 (network) switches. The cards perform routing between virtual LANs (VLANs).
Layer 3 switch devices that house routing-device type cards are called hybrids.
