kldload ip_mroute.ko vs. kernel options MROUTING

[Chris Ernst]

Dear Mailinglist

I just found out that there are two possibilities to get multicast 
working in FreeBSD

There is:
- kldload ip_mroute.ko or
- to compile the kernel with: options MROUTING

Is there a difference between these two approaches?
I notice that, with a custom kernel, patching is much more complex and 
time consuming. As binary updates are not possible any more.

thank you for any replay
best regards
