Configuration considerations
Configure BGP to redistribute routes from OSPF on Router B, so Router A can obtain the route to
9.1.2.0/24. Configure OSPF to redistribute routes from BGP on Router B, so that Router C can obtain the
ro u t e t o 8 .1.1.0 / 24 .
Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF:
Enable OSPF in AS 65009, so Router B can obtain the route to 9.1.2.0/24.
# Configure Router B.
<RouterB> system-view
[RouterB] ospf 1
[RouterB-ospf-1] area 0
[RouterB-ospf-1-area-0.0.0.0] network 2.2.2.2 0.0.0.0
[RouterB-ospf-1-area-0.0.0.0] network 9.1.1.0 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 1
[RouterC-ospf-1] import-route direct
[RouterC-ospf-1] area 0
[RouterC-ospf-1-area-0.0.0.0] network 9.1.1.0 0.0.0.255
[RouterC-ospf-1-area-0.0.0.0] quit
[RouterC-ospf-1] quit
3. Configure the EBGP connection:
Configure the EBGP connection and inject network 8.1.1.0/24 to the BGP routing table of Router
A, so Router B can obtain the route to 8.1.1.0/24.
# Configure Router A.
<RouterA> system-view
[RouterA] bgp 65008
[RouterA-bgp] router-id 1.1.1.1
