[Xorp-users] XORP - Linux - Multicast setup help

[Lucky Stud]

Hi,

I am trying to setup the xorp on a linux (RHEL4) machine with 3 interfaces
which routes the traffic for two subnets (setup below). eth0 is directly
connected to the a cisco router. I need to enable multicast routing in order
to be able to use norton ghost and multicast to image the machines in the
192.0/26 and 192.64/26 subnets and also to receive a multicast video feed
transmission from internet. cisco router is setup properly as I can use
multicast on all other subnets that are directly connected to the cisco
router. The two subnets behind the linux router are live ip and not natted.

I am not sure how to setup the static-rps and/or the bootstrap for the
pimsm4 directive to get it to work properly. which interface needs to be the
BSR or RP or just use the static rps.

Any advise is greatly appreciated.

I downloaded the latest version of xorp from official site, compiled and
installed it.

Thanks.
