[Xorp-users] Guidance needed.

[Pavlin Radoslavov]

For your OS (FreeBSD-7.0), you need to recompile your kernel with
the following option added to your kernel config:

options         MROUTING                # Multicast routing

It is in the XORP User Manual in the PIM-SM chapter.

> New to Xorp so pardon any obvious blunders.  I am trying to configure a uni/multicast router/firewall for a small subnet.  Campus uses PIM-SM for multicast transmission (see diagram above, IP's obfuscated).  I have performed the majority of the cconfiguration from xorpsh to avoid syntax prblems however I am encountering a problem that is completely killing me...  Whenever I try and activate mfea4 i receive errors that I believe are halting me from bringing up pimsm and IGMP.  If you could please review my config and provide feedback I would greatly appreciate it.  Also I am confused as to what (if any) kernel mods sysctl flags etc etc might be needed to get this puppy off the ground.  Any assistance in this matter would be greatly appreciated.
