[dev] PIM VRF

[Donald Sharp]

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!
