Hello everybody,
I've a question about multicast routing on Layer 3 switch. Currently we have a Layer 3 switch (Core switch: Catalyst 6880x) with SVI configured. Multicast routing is configured for some SVI (Ip pim sparse-mode). Is there a way to prevent multicast traffic between some VLAN and allowed for some other VLAN.
Example:
4 VLAN: VLAN 1, VLAN 2, VLAN 3, VLAN 4
Same application for all VLAN that use multicast address: 239.20.20.20
I'd like to allow multicast routing between VLAN 1 & 2 together (and deny to all other VLAN)
And allow mutlicast routing between VLAN 3 & 4 together (and deny to all other VLAN)
What's the best way to do this? ACL? Others solutions?
Thanks for your response.
Greg.
