[Xorp-hackers] {Disarmed} Re: xorp: enable IGMP/PIM-SM over a VLAN interface on Linux

[Eric S. Johnson]

Here is a working config file for vlans and multicast using a recent 
svn pull (1.8.5-WIP) on centos 5 linux.

As Ray mentioned, its better to let the OS create the vlans 
and let xorp deal with them as "real" interfaces with a single vif.

Note the fib2mrib and plumbing mfea sections.
