Jika tadi kita menggunakan interface physical sebagai neighbor peers eBGP, maka sekarang kita akan mencoba untuk menggunakan IP Loopbacknya
R2(config)#router rip
R2(config-router)#net 23.0.0.0
R3(config)#router rip
R3(config-router)#network 23.0.0.0
R3(config-router)#network 3.0.0.0
Kemudian kita konfigurasi BGP nya
R2(config-router)#router bgp 12
R2(config-router)#no neighbor 23.23.23.23 remote-as 3
R2(config-router)#neighbor 3.3.3.3 remote-as 3
R2(config-router)#neighbor 3.3.3.3 update-source lo0
R2(config-router)#neighbor 3.3.3.3 ebgp-multihop
R3(config)#router bgp 3
R3(config-router)#no neighbor 23.23.23.2 remote-as 12
R3(config-router)#neighbor 2.2.2.2 remote-as 12
R3(config-router)#neighbor 2.2.2.2 update-source lo0
R3(config-router)#neighbor 2.2.2.2 ebgp-multihop
Kemudian advertise Loopback 1 R3
R3(config)#int lo1
R3(config-if)#ip add 33.33.33.33 255.255.255.255
R3(config)#router bgp 3
R3(config-router)#network 33.33.33.33 mask 255.255.255.255
Kemudian kita akan mncoba untuk mengeceknya dengan
R3(config)#do sh ip bgp sum
R3(config)#do sh ip bgp sum
BGP router identifier 3.3.3.3, local AS number 3
BGP table version is 8, main routing table version 8
3 network entries using 384 bytes of memory
3 path entries using 156 bytes of memory
3/3 BGP path/bestpath attribute entries using 372 bytes of memory
1 BGP AS-PATH entries using 24 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
BGP using 936 total bytes of memory
BGP activity 5/2 prefixes, 5/2 paths, scan interval 60 secs
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
2.2.2.2 4 12 6 8 8 0 0 00:02:55 2
Dan coba ping 2.2.2.2
R3(config)#do ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 40/53/76 ms
Hehe, sekarang ente tinggal mencoba - coba lagi
:D
