Can mrouted be used between vlans?

[sparky]

Hi,

currently I'm using IGMPProxy to get multicast packets between vlans, but this has a disadvantage in that packets can only flow upstream on one interface.

I've attempted configuring mrouted to do a similar thing but for some reason it doesn't work and unfortunately the log files are not being very helpful.


Here's my config:

phyint vlan1
phyint vlan2

I have also tried doing things like:

phyint vlan1 boundary 239.255.255.0/24

and

phyint vlan1 metric 1 threshold 1
phyint vlan2 metric 1 threshold 1

Looking at the /etc/mrouted.conf file there are a few examples out of which I got the above config.


Running "mrouted -d" gives the output:

multicast routing is enabled in /etc/sysctl.conf too.

I'm wondering if I've misunderstood something and that mrouted is more like a dynamic routing protocol for multicast to be used between routers rather then in a single system between subnets?


Would someone mind helping me with this?


Thanks.
