Step 4 Configure an EBGP connection.
# Configure Router D.
[RouterD] bgp 10
[RouterD-bgp] peer 10.2.1.2 as-number 20
[RouterD-bgp] import-route direct
[RouterD-bgp] import-route ospf 1
[RouterD-bgp] quit
# Configure Router E.
[RouterE] bgp 20
[RouterE-bgp] peer 10.2.1.1 as-number 10
[RouterE-bgp] ipv4-family unicast
[RouterE-bgp-af-ipv4] network 10.3.1.0 30
[RouterE-bgp-af-ipv4] quit
Step 5 Set the cost of OSPF on Router C.
[RouterC] interface pos 1/0/0
[RouterC-Pos1/0/0] ospf cost 2
[RouterC-Pos1/0/0] quit
[RouterC] interface pos 2/0/0
[RouterC-Pos2/0/0] ospf cost 2
[RouterC-Pos2/0/0] quit
# View the routing table of Router A. As shown in the routing table, the route to the network
segment 10.3.1.0 can be learned through BGP, and the outgoing interface is POS 1/0/0.

NOTE
After the cost of OSPF on Router C is set to 2, Router A chooses only Router B as the intermediate router
to the network segment 10.2.1.0. Router C becomes the backup router of Router B.
