Huawei S1720 Series Configuration Guide

3. Configure the MBGP routes to be advertised.
4. Enable multicast on each Switch.
5. Configure basic PIM-SM functions in each AS and enable the IGMP function on the
interfaces at the host side.
6. Configure the BSR boundary on the interfaces connecting two ASs.
7. Configure the MSDP peers to transfer inter-AS multicast information.
Data Preparation
To complete the configuration, you need the following data:
l AS number of Switch A: 100
l AS number of Switch B, Switch C, and Switch D: 200
l Address of the multicast group (225.1.1.1) and address of the multicast source
(10.10.10.10/24)
NOTE
This configuration example describes only the commands used to configure MBGP.
Procedure
Step 1 Configure the IP addresses for the interfaces on each Switch and the OSPF protocol in the ASs.
# Configure the IP addresses and masks of the interfaces on each Switch according to Figure
9-1. Connect the switches through OSPF and ensure that Switch B, Switch C, and Switch D can
communicate with each other through the network layer and can learn the routes on the LoopBack
interfaces of each other. Configure the switches to dynamically update routes through a unicast
routing protocol. OSPF process 1 is adopted in the configuration and the procedure is not
mentioned here.
Step 2 Configure BGP, enable the MBGP protocol, and configure the MBGP peers.
# Configure BGP and the MBGP peer on Switch A.
[SwitchA] bgp 100
[SwitchA-bgp] peer 192.1.1.2 as-number 200
[SwitchA-bgp] ipv4-family multicast
[SwitchA-bgp-af-multicast] peer 192.1.1.2 enable
[SwitchA-bgp-af-multicast] quit
[SwitchA-bgp] quit
# Configure BGP and the MBGP peer on Switch B.
[SwitchB] bgp 200
[SwitchB-bgp] peer 192.1.1.1 as-number 100
[SwitchB-bgp] peer 193.1.1.1 as-number 200
[SwitchB-bgp] peer 194.1.1.1 as-number 200
[SwitchB-bgp] ipv4-family multicast
[SwitchB-bgp-af-multicast] peer 192.1.1.1 enable
[SwitchB-bgp-af-multicast] peer 193.1.1.1 enable
[SwitchB-bgp-af-multicast] peer 194.1.1.1 enable
[SwitchB-bgp-af-multicast] quit
[SwitchB-bgp] quit
# Configure BGP and the MBGP peer on Switch C.
[SwitchC] bgp 200
[SwitchC-bgp] peer 193.1.1.2 as-number 200
[SwitchC-bgp] peer 195.1.1.2 as-number 200
