Hcip day 9_ BGP experiment

1、 The experimental requirements

Configure according to the requirements of the topology

2、 The topology

3、 The analysis process

1、IP To configure
2、R1 And R2、R4 And R5 Between static
3、AS2 Dynamic routing configuration in
4、AS1（R1） And AS2（R2） Of EBGP Relationship building
5、AS2（R2、R3、R4） Inside IBGP Relationship building
6、AS3（R5） And AS2（R4） Of EBGP Relationship building
7、 Last in R1 and R5 Add a loopback on , Announce to BGP in , For testing
