624 CHAPTER 43: MSDP CONFIGURATION

Configuration procedure

Only the commands related to the MSDP configuration leveraging a BGP route are

listed in this example.

1 Configure the interface IP addresses and unicast routing protocol for each switch

Configure OSPF for interconnection between devices in each PIM-SM domain.

Ensure the network-layer interoperation among Switch A, Switch B and Switch C

in PIM-SM 1, the network-layer interoperation between Switch D and Switch E in

PIM-SM 2, and the network-layer interoperation between Switch F and Switch G

in PIM-SM 3, and ensure the dynamic update of routing information between the

devices in each PIM-SM domain through a unicast routing protocol. Detailed

configuration steps are omitted.

Configure the IP address and subnet mask for each interface as per Figure 190.

Detailed configuration steps are omitted.

2 Enable IP multicast routing, and enable PIM-SM on each interface

# Enable IP multicast routing on Switch C, and enable PIM-SM on each interface.

<SwitchC> system-view

[SwitchC] multicast routing-enable

[SwitchC] interface vlan-interface 100

[SwitchC-Vlan-interface100] pim sm

[SwitchC-Vlan-interface100] quit

[SwitchC] interface vlan-interface 200

[SwitchC-Vlan-interface200] pim sm

[SwitchC-Vlan-interface200] quit

[SwitchC] interface vlan-interface 101

[SwitchC-Vlan-interface101] pim sm

The configuration on Switch A, Switch B, Switch D, Switch E, Switch F and Switch

G is similar to the configuration on Switch C.

# Configure BSR boundary on Switch C.

[SwitchC-Vlan-interface101] pim bsr-boundary

[SwitchC-Vlan-interface101] quit

The configuration on Switch D and Switch F is similar to the configuration on

Switch C.

3 Configure Loopback 0 and the position of C-BSR, and C-RP

# Configure the position of Loopback0, C-BSR, and C-RP on Switch C.
