so i don't know what is the use of this command
The following example causes this multicast static route to take effect if
the unicast routes for any given destination go away:
ip mroute 224.0.0.0 255.255.255.255 serial0 200
in the following link
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/himc_r/mlt_i1h.htm#wp1073735
did you have any idea.
thanks in advance
