Downloading Feature Overview
Downloading Feature Overview
The selective Multicast Virtual Route Forwarding (MVRF) downloading feature disables the automatic
downloading of VRF multicast routes for a specific VRF to any line card that does not have a forwarding
interface in that VRF. Starting with Release 12.0(32)SY, this is the default behavior.

The selective MVRF Download feature allows Multicast Virtual Routing and Forwarding (MVRF)
routing instances to be downloaded to line cards as needed instead of downloading to all line cards. The
advantage is that this action saves line card memory by reducing the number of mroutes configured and
lowers the use of the CPU by the line card.
