I have a problem when designed a network for streaming server collect IP camera Sources.

– My devices include: 1 Streaming Server (collects many source from camera and other), 1 Router 2921, 1 Switch 2960 and some source IP camera (ex: CCTV,…, Local ip camera). So what solution for this network:

– My design: Camera sources - Other network – Router 2921 (inside) — Switch 2960–(VLAN10:Local Camera, VLAN 20: CCTV, VLAN 30:Other camera, VLAN 40:Streaming Server, VLAN50:Clients Computer)

So, i want to ask about basic configure in this network:

– On Router 2921: Creat Sub interface connect with Switch int mode trunk, and what about multicast (how to configure multicast to enough funtions in this case: enable multicast-routing, PIM for route and enable igmp snooping for each interface)?

– On Switch 2960: Creat VLANs mode access for sources, configure igmp snooping

Can you example to me some idea and some command to process this situation?

Many Thanks,

---

1. All SVIs must be on your router.  
1.1 Router on a stick configuration
2. Enable ip igmp snooping on your switch
3. Enable ip igmp snooping and ip igmp snooping querier on your router
4. Enable ip multicast-routing on your router
5. Enable ip pim sparse-mode per SVI  
#int vlan 10  
#ip pim sparse-mode
6. Configure rendevous point for your multicast tree  
#ip pim autorp OR ip pim rp-address \<SVI for VLAN 10\>
