What is inter-VLAN routing on a layer 3 switch?
SVI is a logical interface on a multilayer switch that provides layer 3 processing for packets to all switch ports associated with that VLAN. A single SVI can be created for a VLAN.
How do I allow traffic to VLANs?
The simplest way to enable routing between the two VLANs to simply connect an additional port from each VLAN into a Router. The Router doesn’t know that it has two connections to the same switch — nor does it need to. The Router operates like normal when routing packets between two networks.
Is multicast Layer 2 or Layer 3?
In most cases, multicast packets must pass through Layer 2 switching devices between multicast receivers and Layer 3 multicast routers. After a router forwards multicast packets to a switch, the switch forwards the multicast packets to multicast receivers. IGMP snooping is an IPv4 Layer 2 multicast protocol.
Is SVI a Layer 3?
A switch virtual interface (SVI) represents a logical Layer-3 interface on a switch. VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing.
How to configure intervlan routing on Layer 3 Cisco switches?
If you need information on how to configure VLANs, access ports, and trunking on the 3550, refer to Creating Ethernet VLANs on Catalyst Switches for the specific Cisco IOS version you run on the switch. The information in this document is based on a Catalyst 3550-48 that runs Cisco IOS Software Release 12.2 (44)SE6 EMI.
How to enable multicast routing on a VLAN?
4500(config)# ip multicast-routing and then on under each vlan interface you want to enable multicast on int vlan ip pim dense-mode note you can use sparse-mode if you want but you need additional configuration. The above should at least let us know if the above is the problem.
How to solve intervlan multicast-Cisco community?
Solved: InterVLAN Multicast – Cisco Community Solved: We have 2 VLAN’s setup on a Cisco 4500 series switch that is running Cisco IOS. We are using Symantec Ghost and it is working fine on a single VLAN, however Multicast traffic is not crossing over to the other VLAN.

Do you need Pim to enable multicast routing?
You need to enable multicast routing with PIM on the two vlan interfaces. You probably need the IP Services image (or equivalent) to use PIM though. Ie.
