HP Procure Multicast Configuration
Overview
Components Used
- Fog server running version 0.30
- HP ProCurve 5406zl (core layer 3 router)
- HP ProCurve 4108 (building layer 2 Switch)
- HP ProCurve 2520 (layer 2 Switch on my desk)
- 2 PCs
Setup
- 3 Subnets (and VLANs) one for servers and two for students/staff
- FOG server on vlan 1 with IP address 192.168.19.77 - connected to the 5406zl
- 2 PCs on vlan 4 with IP address lease from DHCP (192.168.18.x) NOT from FOG server - connected to the 2520
Procuve Router Commands - Layer 3
commands here are modified extracts of http://cdn.procurve.com/training/Manuals/3500-5400-6200-6600-8200-MRG-Mar10-K_14_52.pdf page 3-20
connect via telnet to Router (5406zl)

switch may need to be rebooted if router PIM was not already enabled consult manual for exact details on your switch
Procurve Switch Commands - Layer 2
Commands for the layer 2 switches to enable IGMP routing While applying these settings to sub-switches is not required, not enabling IMGP on the switch may create excessive traffic to ALL nodes of the switch during a multicast session.
By enabling IGMP allows the switch to send multicast packets to only the computers who have joined the session.
ProCurve# config ProCurve(config)# ip routing ProCurve(config)# ip multicast-routing ProCurve(config)# vlan 1 ProCurve(vlan-1)# ip igmp ProCurve(vlan-1)# vlan 4 ProCurve(vlan-4)# ip igmp ProCurve(vlan-4)# vlan 5 ProCurve(vlan-5)# ip igmp ProCurve(vlan-5)# write mem ProCurve(vlan-5)# exit
