Pada pembahasan sebelumnya kita sudah selesai dan berhasil mengkonfigurasi MPLS pada jaringan ISP.. selanjutnya pada postingan kali ini kita akan membahas konfigurasi IBGP antar router PE yaa..
Oke langsung saja kita konfigurasikan IBGP yaa.. ingat bahwa kita hanya akan melakukan konfigurasi IBGP pada router PE yaa
R2(config)#router bgp 10
R2(config-router)#neighbor PE peer-group
R2(config-router)#nei PE remote-as 10
R2(config-router)#neighbor PE update-source lo0
R2(config-router)#nei 5.5.5.5 peer-group PE
R2(config-router)#nei 6.6.6.6 peer-group PE
R2(config-router)#nei 7.7.7.7 peer-group PE
R2(config-router)#nei 8.8.8.8 peer-group PE

R7(config-router)#nei 6.6.6.6 peer-group PE
R7(config-router)#nei 8.8.8.8 peer-group PE
R7(config-router)#address-family vpnv4

R8(config-router-af)#nei 6.6.6.6 activate
R8(config-router-af)#nei 7.7.7.7 activate
Oke sampai saat ini kita sudah selesai konfigurasi IBGP pada seluruh router PE.. untuk pengujian kita bisa menggunakan perintah berikut
R2(config-router-af)#do sh ip bgp vpnv4 all sum
BGP router identifier 2.2.2.2, local AS number 10
BGP table version is 1, main routing table version 1
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd
5.5.5.5 4 10 10 10 1 0 0 00:05:51 0
6.6.6.6 4 10 8 7 1 0 0 00:05:17 0
7.7.7.7 4 10 6 5 1 0 0 00:03:02 0
8.8.8.8 4 10 2 2 1 0 0 00:00:12 0
Pastikan bahwa setiap router PE sudah bertetangga dengan keempat router PE lainnya..
R5(config-router-af)#do sh ip bgp vpnv4 all sum
BGP router identifier 5.5.5.5, local AS number 10
BGP table version is 1, main routing table version 1

Okeee.. kita sudah selesai dan berhasil.. karena sudah berhasil, artinya pertemuan kita akan berahir lagi yaa.. hehe.. tapi jangan hawatir.. kita akan segera ketemu lagi kog.. karena memang seri superlab ini belum berahir.. hehehe.. pada episode selanjutnya in syaa allah kita akan membahas konfigurasi PE dan CE.. oke sampai jumpa lagi yaa..!!
