BGP federal experiment

        

requirement

 1, AS1 There are two loops , One address is 192.168.1.0/24 This address cannot be declared in any agreement , AS3 There are two loops , One address is 192.168.2.0/24 This address cannot be declared in any agreement , Finally, it is required that the two loops can communicate with each other ,AS1 The other loopback of is 10.0.0.0/24, AS3 The other loopback of is 11.0.0.0/24.
2, Whole AS2 Of IP The address is 172.16.0.0/16, Please divide reasonably
3,AS Backbone link between IP The address can be customized at will
4, Use BGP The protocol allows the loopback of all devices in the whole network to access each other
5, Reduce the number of routing entries , Avoid loop problems
