Configuration procedure

1.

Configure the IP address and subnet mask for each interface as per

Figure 59

. (Details not shown.)

2.

Configure OSPF on switches in each AS to make sure the network-layer is interoperable among
each AS, and routing information between the switches can be dynamically updated. (Details not
shown.)

3.

Enable IP multicast routing, enable PIM-SM on each interface, and configure a PIM-SM domain
border:
# Enable IP multicast routing on Switch A, enable PIM-SM on each interface, and enable IGMP on
the host-side interface VLAN-interface 200.

<SwitchA> system-view

[SwitchA] multicast routing-enable

[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

[SwitchA] interface vlan-interface 200

[SwitchA-Vlan-interface200] igmp enable

[SwitchA-Vlan-interface200] pim sm

[SwitchA-Vlan-interface200] quit

# Enable IP multicast routing, PIM-SM, and IGMP on Switch B, Switch C, Switch D, Switch E, and
Switch F in the same way. (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. (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 loopback 0

[SwitchB-pim] c-rp loopback 0

[SwitchB-pim] quit

# Configure C-BSRs and C-RPs on Switch C and Switch E in the same way. (Details not shown.)

5.

Configure BGP for mutual route redistribution between BGP and OSPF:
# Configure an EBGP peer, and redistribute OSPF routes on Switch B.

[SwitchB] bgp 100

[SwitchB-bgp] router-id 1.1.1.1

[SwitchB-bgp] peer 192.168.1.2 as-number 200

[SwitchB-bgp] import-route ospf 1

[SwitchB-bgp] quit
