Description (partial)


The problem shows up whenever enabling or disabling <CmdBold>ipv6 multicast multipath<noCmdBold>.
This will immediately cause <CmdBold>ipv6 multicast rpf use-bgp<noCmdBold> to be enabled or 
disabled (respectively). Since "multipath" is enabled by default, it only appears in config if
it is disabled, and it appears after <CmdBold>ipv6 multicast rpf use-bgp<noCmdBold> which only is 
present when enabled. The effect will be that "use-bgp" becomes disabled if "multipath" is 


The problem shows up whenever enabling or disabling <CmdBold>ipv6 multicast multipath<noCmdBold> 
or a router starting up with this disabled in the config. The problem is harmless if "use-bgp" 
ends up with the desired setting anyway. E.g. if one wants both "multipath" and "use-bgp" to be 
enabled (or disabled).
