Item Network requirements
IP multicast routing
• Enable IP multicast routing on the P device.
• Enable IP multicast routing on the public network on PE 1, PE 2, and PE 3.
• Enable IP multicast routing in VPN instance a on PE 1, PE 2, and PE 3.
• Enable IP multicast routing in VPN instance b on PE 2 and PE 3.
• Enable IP multicast routing on CE a1, CE a2, CE a3, CE b1, and CE b2.
IGMP
• Run IGMPv2 on VLAN-interface 20 of PE 1.
• Run IGMPv2 on VLAN-interface 40 of CE a2, VLAN-interface 50 of CE a3, and
VLAN-interface 60 of CE b2.
PIM
• Enable PIM-SM on all interfaces of the P device.
• Enable PIM-SM on all public and private network interfaces of PE 1, PE 2 and PE 3.
• Enable PIM-SM on all interfaces of CE a1, CE a2, CE a3, CE b1, and CE b2.
• Configure Loopback 1 of P as a C-BSR and a C-RP for the public network (to work for
all multicast groups).
• Configure Loopback 1 of CE a2 as a C-BSR and a C-RP for VPN a (to work for all
multicast groups).
• Configure Loopback 2 of PE 3 as a C-BSR and a C-RP for VPN b (to work for all
multicast groups).
