As shown below, all devices of company A belong to AS 65008 while all devices of company B belong to 

AS 65009. AS 65008 and AS 65009 are connected through Switch A and Switch B. It isi required that 

Switch A can access network 9.1.2.0/24 in AS 65009, and Switch C can access network 8.1.1.0/24 in 

AS 65008.

1)  Configure IP addresses for interfaces (omitted) 

2)  Configure OSPF  

Enable OSPF in AS 65009, so that Switch B can obtain the route to 9.1.2.0/24.

3)  Configure the eBGP connection 

Configure the eBGP connection and inject network 8.1.1.0/24 to the BGP routing table of Switch A, so 

that Switch B can obtain the route to 8.1.1.0/24.
