[Xorp-users] OpenBSD IGMP/PIM Issue

[Stegen Smith]

Hello All,

I've got encountered an issue while trying to run xorp on an OpenBSD  
4.3 i386 GENERIC system using IGMP and PIM.
I've got net.inet.ip.forwarding and net.inet.ip.mforwarding enabled,  
and I'll paste my config below.

interfaces {
    restore-original-config-on-shutdown: false
    interface vlan40 {
        description: "data interface"
        disable: false
        default-system-config
    }
}

fea {
    unicast-forwarding4 {
        disable: false
    }
    click {
        disable: true
    }
}

plumbing {
    mfea4 {
        disable: false
        interface vlan40 {
            vif vlan40 {
                disable: false
            }
        }
        interface register_vif {
            vif register_vif {
                disable: false
            }
        }
        traceoptions {
            flag all {
                disable: false
            }
        }
    }
}

protocols {
    igmp {
        disable: false
        interface vlan40 {
            vif vlan40 {
                disable: false
                version: 2
                enable-ip-router-alert-option-check: false
                query-interval: 30
                query-last-member-interval: 1
                query-response-interval: 10
                robust-count: 2
            }
        }
        traceoptions {
            flag all {
                disable: false
            }
        }
    }
    pimsm4 {
        disable: false
        interface vlan40 {
            vif vlan40 {
                disable: false
                dr-priority: 1
                hello-period: 30
                hello-triggered-delay: 5
            }
        }
        interface register_vif {
            vif register_vif {
                disable: false
            }
        }
        bootstrap {
            disable: false
            cand-bsr {
                scope-zone 224.0.0.0/4 {
                    is-scope-zone: false
                    cand-bsr-by-vif-name: "vlan40"
                    cand-bsr-by-vif-addr: 10.3.48.2
                    bsr-priority: 1
                    hash-mask-len: 30
                }
            }
        }
        switch-to-spt-threshold {
            /* approx. 1K bytes/s (10Kbps) threshold */
            disable: false
            interval: 100
            bytes: 102400
        }

        traceoptions {
            flag all {
                disable: false
            }
        }

    }
}

Note that I've only got it enabled on vlan40 because I'm not seeing  
any igmp queries coming from the system at all, and I just wanted a  
trimmed down configuration until I can see the queries.  Now here's an  
interesting log entry that I've seen.

[ 2008/10/07 23:38:13 WARNING xorp_fea XrlFeaTarget ] Handling method  
for raw_packet4/0.1/send failed: XrlCmdError 102 Command failed  
sendmsg(proto 2 size 32 from 10.3.48.2 to 224.0.0.1 on interface  
vlan40 vif vlan40) failed: No route to host

I saw something similar in an older post, but there wasn't any follow  
up to it:
http://mailman.icsi.berkeley.edu/pipermail/xorp-users/2004-December/000332.html

I'm sure that other folks have gotten this to work on other openbsd  
systems, but I'm not sure what I'm missing.  I'm using an intel em0  
interface for vlan40, and MULTICAST is enabled on the interface.  I  
must just be missing something silly!

I'm also not sure if I should have fib2mrib enabled or not, but when I  
do enable it, the xorp_fib2mrib module dies.

So I've got it disabled for now, but I figured I'd let this issue be  
known too.

If anyone could provide me with some insight as to what I'm missing  
I'd definitely be appreciative as I'd love to get this working. =)   
Also please let me know if I should provide any more information.

thanks for the help
