# Configure PE 1, ASBR-PE 1, ASBR-PE2, PE 2, and CE a2 in the same way CE a1 is configured.
(Details not shown.)
2. Configure a unicast routing protocol and MPLS L3VPN inter-AS option A on all devices so that all
devices in the ASs are interoperable at the network layer. (Details not shown)
For more information about configuring basic MPLS VPN, see MPLS Configuration Guide.
3. Enable IP multicast routing on the public network, and enable PIM-SM on the public network
interfaces (including Loopback interfaces):
# On PE 1, enable IP multicast routing, and enable PIM-SM on the public network interfaces.
