# Enable multicast on SwitchB and enable PIM-SM on each interface. The configurations of
other Switches are similar to the configuration of SwitchB, and are not provided here.
[SwitchB] multicast routing-enable
[SwitchB] interface vlanif 100
[SwitchB-Vlanif100] pim sm
[SwitchB-Vlanif100] quit
[SwitchB] interface vlanif 200
[SwitchB-Vlanif200] pim sm
# Configure the domain boundary on VLANIF 100 of SwitchB.
[SwitchB-Vlanif100] pim bsr-boundary
[SwitchB-Vlanif100] quit
# Configure the domain boundary on VLANIF 200 and VLANIF 400 of SwitchC. Configure
the service boundary of BSR on VLANIF 400 of SwitchE. The configuration on SwitchE is
similar to the configuration on SwitchB, and is not provided here.
# Enable IGMP on the interface connecting SwitchD to the leaf network.
[SwitchD] interface vlanif 102
[SwitchD-Vlanif102] igmp enable
Step 4 Configure the C-BSR and C-RP.
# Create Loopback0, and then configure a C-BSR, and a C-RP on Loopback0 on SwitchB. The
configurations of SwitchC and SwitchE are similar to the configuration of SwitchB, and are not
provided here.
[SwitchB] interface loopback 0
[SwitchB-LoopBack0] ip address 1.1.1.1 255.255.255.255
[SwitchB-LoopBack0] pim sm
[SwitchB-LoopBack0] quit
[SwitchB] pim
[SwitchB-pim] c-bsr loopback 0
[SwitchB-pim] c-rp loopback 0
[SwitchB-pim] quit
Step 5 Configure MSDP peer relations.
# Configure the MSDP peer relationship on SwitchB.
[SwitchB] msdp
[SwitchB-msdp] peer 192.168.2.2 connect-interface vlanif200
[SwitchB-msdp] quit
# Configure the MSDP peer relationship on SwitchC.
[SwitchC] msdp
[SwitchC-msdp] peer 192.168.2.1 connect-interface vlanif200
[SwitchC-msdp] peer 192.168.4.2 connect-interface vlanif400
[SwitchC-msdp] quit
# Configure the MSDP peer relationship on SwitchE.
[SwitchE] msdp
[SwitchE-msdp] peer 192.168.4.1 connect-interface vlanif400
[SwitchE-msdp] quit
Step 6 Verify the configuration.
# Run the display bgp peer command to view the BGP peer relationship between Switches. For
example, the following information shows the BGP peer relationship on SwitchB and SwitchC:
<SwitchB> display bgp peer
BGP local router ID : 1.1.1.1
