Configuration procedure
1.
Assign an IP address and subnet mask to each interface according to
shown.)
2.
Configure OSPF on the switches to meet the following requirements: (Details not shown.)
The switches in each AS are interoperable at the network layer.
The switches can dynamically update routing information.
3.
Enable IP multicast routing, enable PIM-SM on each interface, and configure a PIM-SM domain
border:
# On Switch A, enable IP multicast routing.
<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit
# Enable PIM-SM on VLAN-interface 103 and VLAN-interface 100.
[SwitchA] interface vlan-interface 103
[SwitchA-Vlan-interface103] pim sm
[SwitchA-Vlan-interface103] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] pim sm
[SwitchA-Vlan-interface100] quit
# Enable IGMP on VLAN-interface 200 (the interface that connects to the receiver host).
[SwitchA] interface vlan-interface 200
[SwitchA-Vlan-interface200] igmp enable
[SwitchA-Vlan-interface200] quit
# Enable IP multicast routing and PIM-SM on Switch B, Switch C, Switch D, Switch E, and Switch
F in the same way Switch A is configured. (Details not shown.)
# Configure a PIM domain border on Switch B.
[SwitchB] interface vlan-interface 101
[SwitchB-Vlan-interface101] pim bsr-boundary
[SwitchB-Vlan-interface101] quit
# Configure a PIM domain border on Switch C and Switch E in the same way Switch B is
configured. (Details not shown.)
4.
Configure C-BSRs and C-RPs:
# Configure Loopback 0 as a C-BSR and a C-RP on Switch B.
[SwitchB] pim
[SwitchB-pim] c-bsr 1.1.1.1
[SwitchB-pim] c-rp 1.1.1.1
[SwitchB-pim] quit
# Configure C-BSRs and C-RPs on Switch C and Switch E in the same way Switch B is configured.
(Details not shown.)
5.
Configure BGP for mutual route redistribution between BGP and OSPF:
# On Switch B, configure an eBGP peer, and redistribute OSPF routes.
[SwitchB] bgp 100
[SwitchB-bgp] router-id 1.1.1.1
[SwitchB-bgp] peer 192.168.1.2 as-number 200
