Troubleshooting

Efficient Video Distribution Networks with.Multicast: IGMP Querier and PIM-DM

3. Enable routing, which will set up static routing on the first switch to route between VLANs.

4. Enable PIM-DM on the first switch. PIM must be set globally as well as on each VLAN.

5. Disable IGMP snooping on the first switch. Enable IGMP globally and on each VLAN.

6. Create VLANs 10, 20, and 30 on the second switch, assigning each an IP address.

Note: Layer 2 switches do not require an IP address on each VLAN, but assigning them could

come in handy for troubleshooting connectivity.

7. Enable IGMP snooping on the second switch (this is enabled by default starting with firmware

5.1.x.x).

8. On both switches, for each trunk port (going from one switch to another switch), configure

the port in trunk mode, allowing VLANs 10, 20, and 30 on each trunk port.

9. On both switches, for each access port (going to a video server or client), configure the port

in access mode and assign them to a VLAN. For this scenario, Video Server 1 is on VLAN 10

and Video Server 2 is on VLAN 40. The first client is on VLAN 10, the second on VLAN 20, and

the third on VLAN 30.

10. Plug in the server at one end of the network and the clients at the opposite end as shown in

Figure 2. Connect one client to each VLAN. Set IP addresses on clients and servers as

required, and within the same subnet of the VLAN where they are attached.

11. Set the default gateway on each computer to point toward the router. For this example,

each computer will have the default gateway of 10.xx.0.5, where xx is the VLAN the

computer is connected to.
