Hi Laurent,

If you don’t want the Multicast traffic flooding your network then you need to enable IGMP on all Layer 2 switches involved in the traffic between the two Multicast endpoints.

It’s supported, refer to page 22 of the following document – http://support.avaya.com/css/P8/documents/100123708

Cheers!

Thanks a lot !

Concerning IGMP on edge switches, I don’t really understand …

Do I have to enable IGMP on all layer 2 switches to connect both Multicast receivers and transmitters ? Anf thay said that IGMP traffic is not transported over SMLT … hum ….

Thanks again !

You should use a CLIP so your not tied to any single physical interface. If you use say VLAN 1 in your OSPF or PIM configuration and say VLAN 1 goes down you’ll be in trouble. If you use a CLIP then your entire switch would need to go down before you’d have issues with either OSPF or PIM.

You should use BSR preference/priority in combination with a CLIP address.

Just remember you could have multiple Multicast applications running from a single server, so it’s really the application/data stream that you are assigning the Multicast IP address.

Good Luck!

And I have more questions ! :)

If VRRP IP addresses are configured for each VLAN between Edge (5xxx series) and Core (88xx series), should I configure something special concerning CLIP addresses ? Or cbsrpreference can be enough ?

And if I use multiple Multicast servers, should they communicate with a single Multicast address for each of them (in 239.0.0.0/8 range) ?

Thanks !
Laurent.

Hi Michael,

thanks a lot for all your great explanations !

Regarding your example of Multicast Routing, and after hearing of this guide (http://support.avaya.com/css/P8/documents/100123715), I have a question !

They say : “The ERS 5000 does not support IGMP over SMLT/SLT at this time” … and you said “You could enable IGMP (generally disabled by default) to filter the multicast traffic from ports that are not subscribing to any multicast groups” …

So, what is the best practice ? I think we have to enable IGMP on all layer 2 switches to connect both Multicast receivers and transmitters … but if IGMP traffic is not transported over SMLT, how can we do ?

Am I wrong ?

Thanks a lot !

Cheers !
Laurent.

Hi Wyllen,

As I replied on the forums I don’t believe v3.2.x software for the ERS 8600 support circuitless IP interfaces (CLIPs).

Cheers!

Hello,

Is it possible to know what 8600′s version software did you used, because I try to add CLIP interface as you, but it told me : ” config ip “circuitless-ip-int” not found in path /PP8606:6/config/ip
