You may want to take a peek at this link(watch wrap): http://www.cisco.com/univercd/cc/td/doc/product/l3sw/8540/rel_12 _0/w5_11_19/config/8500cnfg.htm#15915 Specifically, I direct your attention to the note listed on the page which states: Note BVIs do not support IP multicast routing. As far as DVMRP is concerned, most Cisco routers interoperate very well with DVMRP, since it came along before PIM however, Cisco routers natively do not support DVMRP as the sole multicast routing protocol. According to this link here, DVMRP tunneling is supported on the CSR: http://www.cisco.com/univercd/cc/td/doc/product/l3sw/8540/cnfg_g d/1cfg8540.htm I have no idea how you would go about configuring it and whether it could be tunneled over a BVI interface.
