[Xorp-users] Help needed for basic PIM-SM configuration

[Kimmo Koivisto]

Hello

I don't have much experience from xorp or PIM-SM and I need some assistance 
setting up xorp for my simple testing environment.

I have RHEL4 + xorp 1.3 based routers R1-R4, multicast sender S1 and receiver 
C1. Sender sends video to the multicast address 225.1.1.1.

At this time, my network is very simple:

[S1]--[R1]-[R2]-[R3]-[R4]-[C1]

All the routers R1-R4 have the same kind of interface setup:

<--{eth0}[Rn]{eth1}-->

Eth0 is towards the S1 and eth1 is towards C1.

I have enabled OSPF and routing is working okay. I have tried to configure 
PIM-SM but did not succeed (what "xorpsh>show pim rps" and "xorpsh>show pim 
bootstrap" should show when everything is in order?). 

All the routers have now this configuration:

<pim-sm-config>
protocols {
    pimsm4 {
	disable: false
	interface eth0 {
	    vif eth0 {
		disable: false
	    }
	}
	interface eth1 {
	    vif eth1 {
		disable: false
	    }
	}
	interface register_vif {
	    vif register_vif {
		disable: false
	    }
	}

	bootstrap {
	    disable: false

	    cand-bsr {
		scope-zone 225.0.0.1/32 {
		    cand-bsr-by-vif-name: "eth0"
		}
	    }

	    cand-rp {
		group-prefix 225.0.0.1/32 {
		    cand-rp-by-vif-name: "eth0"
		}
	    }
	}

	switch-to-spt-threshold {
	    disable: false
	    interval: 100
	    bytes: 102400
	}

	traceoptions {
	    flag all {
		disable: false
	    }
	}
    }
}
</pim-sm-config>

I would appreciate if someone could give me some instructions if my config is 
invalid and how xorp should be configured for this scenario.

Best Regards
