Configuration procedure

1. Configure IP addresses for interfaces. (Details not shown.)

2. Configure OSPF on Router B, Router C, and Router D:

# Configure Router B.

<RouterB> system-view

[RouterB] ospf

[RouterB-ospf] area 0

[RouterB-ospf-1-area-0.0.0.0] network 192.1.1.0 0.0.0.255

[RouterB-ospf-1-area-0.0.0.0] network 194.1.1.0 0.0.0.255

[RouterB-ospf-1-area-0.0.0.0] quit

[RouterB-ospf-1] quit

# Configure Router C.

<RouterC> system-view

[RouterC] ospf

[RouterC-ospf] area 0

[RouterC-ospf-1-area-0.0.0.0] network 193.1.1.0 0.0.0.255

[RouterC-ospf-1-area-0.0.0.0] network 195.1.1.0 0.0.0.255

[RouterC-ospf-1-area-0.0.0.0] quit

[RouterC-ospf-1] quit

# Configure Router D.

<RouterD> system-view

[RouterD] ospf

[RouterD-ospf] area 0

[RouterD-ospf-1-area-0.0.0.0] network 194.1.1.0 0.0.0.255

[RouterD-ospf-1-area-0.0.0.0] network 195.1.1.0 0.0.0.255

[RouterD-ospf-1-area-0.0.0.0] quit

[RouterD-ospf-1] quit

3. Configure BGP connections:

# Configure Router A.

<RouterA> system-view

[RouterA] bgp 100

[RouterA-bgp] peer 192.1.1.2 as-number 200

[RouterA-bgp] peer 193.1.1.2 as-number 200

[RouterA-bgp] address-family ipv4 unicast

[RouterA-bgp-ipv4] peer 192.1.1.2 enable

[RouterA-bgp-ipv4] peer 193.1.1.2 enable
