All - The ability for PIM to work within the context of linux VRF's has been committed into master. To configure for a VRF: vrf red <---- VRF configuration, same as global configuration ip pim ecmp ip pim rp 99.1.1.1 224.0.0.0/4 interface vrf red ip pim sm The 'interface vrf red' is treated like the loopback. So if you intend to use the particular router as a RP you should configure an ip address on your vrf device and configure pim to use it. interface swp1 vrf red <----- Turn on pim on the interface as per normal ip pim sm interface swp2 vrf red ip pim sm ip igmp thanks! donald
