[SwitchA-bgp-default] router-id 1.1.1.1
[SwitchA-bgp-default] peer 192.168.1.2 as-number 200
# Enable exchange of IPv4 unicast routes used for RPF check with Switch B.

[SwitchA-bgp-default-mul-ipv4] peer 192.168.1.2 enable
# Redistribute direct routes into BGP.

5. Configure MSDP peers:
# Configure an MSDP peer on Switch A.
[SwitchA] msdp
[SwitchA-msdp] peer 192.168.1.2 connect-interface vlan-interface 101
[SwitchA-msdp] quit
# Configure an MSDP peer on Switch B.
[SwitchB] msdp
[SwitchB-msdp] peer 192.168.1.1 connect-interface vlan-interface 101
[SwitchB-msdp] quit
Verifying the configuration
