31.4 MBGP Multicast Extension Configuration Example

I. Networking requirement
This example describes how the administrator uses the MBGP attributes to manage
route selection. All switches are configured with MBGP. The IGP in AS200 uses OSPF.
Switch A is AS100 and serves as the MBGP neighbor of Switch B and Switch C in
AS200. Switch B and Switch C run IBGP for Switch D in AS200. Switch D is also in
AS200.

III. Configuration procedure
1) Configure Switch A:
[SwitchA] vlan 20
[SwitchA-vlan20] port ethernet1/1/2
[SwitchA-vlan20] quit
[SwitchA] interface vlan-interface 20
[SwitchA-Vlan-interface20] ip address 192.1.1.1 255.255.255.0
[SwitchA-Vlan-interface20] quit
[SwitchA] vlan 30
[SwitchA-vlan30] port ethernet1/1/3
[SwitchA-vlan30] quit
[SwitchA] interface vlan-interface 30
[SwitchA-Vlan-interface30] ip address 193.1.1.1 255.255.255.0
[SwitchA-Vlan-interface30] quit
Enable MBGP.
[SwitchA] bgp 100
[SwitchA-bgp] ipv4-family multicast
Specify target network for MBGP.
