Hi all,
I'm doing routed access design with following:
- Routing protocol is OSPF.
- 3 layers with: Core/Distribution/Access design.
- Core: Catalyst 6500E Sup 2T.
- Distribution: ME 3800X / Catalyst 4500X.
- Access: ME 3400E.
We enable PIM from Core to Access layer.
At the moment, there are around 1000 multicast group in the network.
Cisco hardware limitation of multicast:
- Cisco ME 3400E can only support up to 1000 IGMP groups and multicast routes.
- Cisco ME 3800X can only support up to 2000 IGMP group and multicast routes with Metro IP Services license.
- Cisco Catalyst 4500X support up to 32K multicast routes.
- Cisco Catalyst 6500E Sup 2T support up to 128K multicast routes.
Requirement:
Design the network to support up to 2500 multicast groups.
So, are there any fine-tune in the design to meet above requirement?
Or I have to change access layer switch to higher model? (ex: 4500E)
Thanks,
