Multicast routing

RouterOS Forwarding Protocols
1

Hi all!

I have such scheme:

Streamers (10.1.1.0/24, 10.1.2.0/24) (int vlan10)CCR1016(int vlan20) (10.0.0.0/24) Customers

It was configured PIM and RP on CCR:
/routing pim interface
add alternative-subnets=0.0.0.0/0 interface=ether1.10
add alternative-subnets=0.0.0.0/0 interface=ether1.20
/routing pim rp
add address=10.255.255.1

10.255.255.1 - loopback on bridge interface

So, CCR registered every group streamers sent, that`s ok.

On customer switch I can see subscription on different group from access port (from customer), I see right router port (connected to CCR), but there is no traffic.

Help me, please!

Are you allowing the necessary traffic in IP Firewall Filters?

3

There is no any rule in ip firewall filter. I disabled it at all.

4

Any ideas?

5

add your loopback interface too. or add that IP address to one of the interfaces where multicast is allowed.

6

Thank you, Janisk, for you message.
I added loopback interface to PIM configuration, but it did not help, still does not work.

7

i hope it is fully routed network. and your loopback is reachable from somewhere else.

8

Loopback is reachable from streamer and customer networks, so I think that should be enough everything works fine, is not it?

9

for PIM configuration - try to reboot the router, as there is long stating problem that sometimes configuration changes are not applied. We are working on new PIM. Or if it is possible to use use IGMP-proxy.

10

I can not use IGMP Proxy.
I will try to reboot CCR soon and will tell a result.

11

CCR was rebooted, unfortunately it didn’t help.

12

So, tell me somebody please, should PIM works on CCR, or it will be better to buy DGS-3620 (it works fine with it)?

13

Im still fiddling, but I don’t think PIM works on CCR.

My PIM BSR is at my core network. RB1100AHx2 worked fine with it. CCR doesn’t seem to. BUT, there are some other changes I made when I put the CCR in that I have to work backwards through before I say it doesn’t work for sure.

All I can say now is, the CCR sees the neighbors across the vlan links to the core and the neighbors across the GRE tunnels to the endpoints, but doesn’t pick up the RP or BSR address.

I also noticed that (On all ROS devices) that Mikrotik PIM doesn’t respect the DR priority and always tries to go to the highest IP address. Thats definitely a bug.

I have PIM on DGS-3627, the model before 3620 series, which is maintaining IPTV vlan for about 100 STB’s and two other ISPs with about 500 STBs each, TV is working smoothly. I’ll say go for D-Link. MT is unfortunately not yet ready for core.

15

Works fine on RB1100AHx2. Same config on a CCR1036 doesn’t work.

Im kind of TO’d.. GRE over IPSEC doesn’t work, PIM doesn’t work… The 2 biggest reasons I need these and neither work.

Yay.

Hi,

Have dealed with MT-s PIM for a long time and with different kind of hw. Ended up with x86 + couple of RB44 (http://www.interprojekt.com.pl/mikrotik-rb44ge-four-port-gigabit-server-adapter-p-1380.html)
The most flexible, and cheapest solution.

We have had problems with RB1100AXx2 when we decided to replace RB1100AH with them. Once 1,5 years ago with ROS 5.x and couple of weeks ago tried RB1100AHx2 ROS 6.12, the same sympthoms:

Random jitterings on streamed channels, however the AHx2 must have at least 2 times more power.
Dont know people how your AHx2 are working doing PIM - maybe you are streaming 1-2 channels, dont know, but first time we tried with 60 channels coming from two RP and very quickly moved back to the 1100AH. The last try was in another place with different working configuration (RB1100AH) and also random jitters.

Suspect there should be some RB multicore cpu + multicast big bug. Even SOHO RB951 is dealing PIM ok :wink:

So my 200€ Phenom X6 is hammering and routing like a horse multicast without any issues 160 concurrent streams, routing the net and doing hotspot + i can upgrade the HW at any time.

Kind regards
