[LSW3-bgp]peer 10.2.2.2 as-number 10

[LSW3-bgp]peer 10.2.2.2 connect-interface LoopBack 0 [LSW3-bgp]peer 10.4.4.4  as-number 10  

[LSW3-bgp]peer 10.4.4.4 connect-interface LoopBack 0

[LSW4]bgp 10

[LSW4-bgp]peer 10.1.1.1 as-number 10

[LSW4-bgp]peer 10.1.1.1 connect-interface LoopBack 0

5. To configure EBGP Connect

[LSW4]bgp 10

[LSW4-bgp]peer 10.1.45.5 as-number 20

[LSW4-bgp]import-route direct  

[LSW4-bgp]import-route ospf 1

[LSW5]bgp 20

[LSW5-bgp]peer 10.1.45.4 as-number 10

[LSW5-bgp]ipv4-family unicast  

[LSW5-bgp-af-ipv4]network 10.2.10.0 24

6. To configure LSW2 On OSPF The cost value of the protocol

[LSW2]int Vlanif 12

[LSW2-Vlanif12]ospf cost 2

[LSW2]int Vlanif 24

[LSW2-Vlanif24]ospf cost 2  

As you can see from the routing table ,LSW3 adopt BGP The protocol can learn the target network segment 10.2.10.0 The routing , The exit interface is Vlanif34; adopt OSPF The protocol can learn the target network segment 10.1.12.0 and 10.1.24.0 The routing , Routing overhead is 2

7. stay LSW3 On the configuration OSPF-BGP Linkage function

[LSW3]ospf 1

[LSW3-ospf-1]stub-router on-startup

8. Check the configuration ： preservation 、 restart LSW3

It can be seen that , adopt BGP The protocol can learn the target network segment 10.2.10.0 The routing , The output interface becomes Vlanif12
