5、 ... and , Announce routing .
（ One ） Declare

[r1]bgp 1
[r1-bgp]network 10.0.0.0 24 
[r8]bgp 3
[r8-bgp]network 11.0.0.0 24

（ Two ） Modify the next jump

[r2-bgp]peer 172.16.3.1 next-hop-local
[r2-bgp]peer 172.16.5.1 next-hop-local
[r7-bgp]peer 172.16.4.1 next-hop-local
[r7-bgp]peer 172.16.6.1 next-hop-local

（ 3、 ... and ） Create a route reflector

[r3-bgp]peer 172.16.2.1 reflect-client   --- Appoint R2 For your customers , For myself RR
[r6-bgp]peer 172.16.5.1 reflect-client   --- Appoint R5 For your customers , For myself RR

 

6、 ... and , Use BGP The protocol allows the loopback of all devices in the whole network to access each other

[r2]ip route-static 172.16.0.0 21 NULL 0
[r2]bgp 64512
[r2-bgp]network 172.16.0.0 21
[r7]ip route-static 172.16.0.0 21 NULL 0
[r7]bgp 64513
[r7-bgp]network 172.16.0.0 21

 

7、 ... and , send 192.168.1.0 And 192.168.2.0 Communicate with each other .

[r1]int t0/0/0
[r1-Tunnel0/0/0]ip address 192.168.3.1 24
[r1-Tunnel0/0/0]tunnel-protocol gre 
[r1-Tunnel0/0/0]source 10.0.0.1
[r1-Tunnel0/0/0]destination 11.0.0.1
[r8]int t0/0/0
[r8-Tunnel0/0/0]ip address 192.168.3.2 24
[r8-Tunnel0/0/0]tunnel-protocol gre 
[r8-Tunnel0/0/0]source 11.0.0.1
[r8-Tunnel0/0/0]destination 10.0.0.1

[r1]ip route-static 192.168.2.0 24 192.168.3.2
[r8]ip route-static 192.168.1.0 24 192.168.3.1
