Cisco (35) -- BGP introduction experiment

 

The topology ：

The experimental requirements ：

By running BGP and MPLS bring R4 On loo 8 And R5 On loo 9 connected .

Experimental instructions ：

1. There are three experimental topologies AS, Each router has its own loo 0 Address , There are also routers R4 There is loo 8 Of 8.8.8.8/24 The loopback address of , In the router R5 There is 9.9.9.9/24 Ring return address of .

2. stay AS 10 Internal operation EIGRP Make in this AS Intercommunication within the whole network .

3.R4 And R2 establish EBGP peers ,R2 And R3 establish IBGP peers ,R3 And R5 establish EBGP peers .

The experimental steps ：

1. Configure the address of the physical interface of each router , And the loopback address .
