Konfigurasi MPLS-BGP



Konfigurasi IP Address

PE 1   : 202.10.5.1/24                e1/1

PE 2   : 202.10.10.1/24             e1/0

LSR 1 : 202.10.5.2/24               e1/0
 : 192.168.2.1/24            e1/1

LSR 2 : 192.168.2.2/24            e1/0
             : 202.10.10.2/24            e1/1

Command Line : PE 1
router (config)# interface ethernet 1/1
router (config-if)# ip address  202.10.5.1 255.255.255.0
router (config-if)# no shutdown

Command Line : PE 2
router (config)# interface ethernet 1/0
router (config-if)# ip address  202.10.10.1 255.255.255.0
router (config-if)# no shutdown

Command Line : LSR 1
router (config)# interface ethernet 1/0
router (config-if)# ip address  202.10.5.2 255.255.255.0
router (config-if)# no shutdown
router (config)# interface ethernet 1/1
router (config-if)# ip address  192.168.2.1 255.255.255.0
router (config-if)# no shutdown
Command Line : LSR 2
router (config)# interface ethernet 1/1
router (config-if)# ip address  202.10.10.2 255.255.255.0
router (config-if)# no shutdown
router (config)# interface ethernet 1/0
router (config-if)# ip address  192.168.2.2 255.255.255.0
router (config-if)# no shutdown

Konfigurasi IP Interface Loopback

PE_1    : 192.168.100.1/32
PE_2    : 192.168.100.4/32
LSR_1 : 192.168.100.2/32
LSR_2 : 192.168.100.3/32


Command Line : contoh PE 1
router (config)# interface loopback 0
router (config-if)# ip address  192.168.100.1 255.255.255.255

Command Line : contoh PE 2
router (config)# interface loopback 0
router (config-if)# ip address  192.168.100.4 255.255.255.255

Command Line : contoh LSR 1
router (config)# interface loopback 0
router (config-if)# ip address  192.168.100.2 255.255.255.255

Command Line : contoh LSR 2
router (config)# interface loopback 0
router (config-if)# ip address  192.168.100.3 255.255.255.255


SETTING ROUTING DYNAMIC

PE 1
#router ospf 100
#network 192.168.1.0 0.0.0.255 area 100            core
#network 192.168.100.1 0.0.0.0 area 100            loopback PE1

PE 2
# router ospf 100
# network 192.168.3.0 0.0.0.255 area 100          core
# network 192.168.100.4 0.0.0.0 area 100          loopback PE2


LSR 1
# router ospf 100
# network 192.168.1.0 0.0.0.255 area 100          PE_1
# network 192.168.2.0 0.0.0.255 area 100          core
# network 192.168.100.2 0.0.0.0 area 100          loopback core
LSR 2
# router ospf 100
# network 192.168.3.0 0.0.0.255 area 100          PE_2
# network 192.168.2.0 0.0.0.255 area 100          core
# network 192.168.100.2 0.0.0.0 area 100          loopback core

Periksa router
# show ip route

Test Ping dari PE 1 Ke LSR 1
# ping 202.10.5.1

Aktifkan BGP

PE 1
# router bgp 100
# no synchronization
# neighbor 192.168.100.3 remote-as 100
# neighbor 192.168.100.3 update-source Loopback0
# no auto-summary

PE 2
# router bgp 100
# no synchronization
# neighbor 192.168.100.1 remote-as 100
# neighbor 192.168.100.1 update-source Loopback0
# no auto-summary

 Cek Status BGP
# show ip bgp neighbors atau
# show ip bgp summary

statusnya harus Active
Aktifkan MPLS

PE 1
# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/1                        connect ke LSR 1
# ip address 202.10.5.1 255.255.255.0
# mpls ip

PE 2
# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/0                        connect ke LSR 2
# ip address 202.10.10.1 255.255.255.0
# mpls ip


LSR_ 1
# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/0                        connect ke PE 1
# ip address 202.10.5.1 255.255.255.0
# mpls ip
# exit

# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/1                        connect ke LSR 2
# ip address 172.16.5.1 255.255.255.0
# mpls ip

LSR_2
# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/0                        connect ke LSR 1
# ip address 202.10.10.1 255.255.255.0
# mpls ip
# exit

# ip cef
# mpls label protocol ldp
# mpls ldp router-id loopback0 force
# interface Ethernet 1/1                        connect ke PE 2
# ip address 172.16.10.1 255.255.255.0
# mpls ip

Cek Status MPLS

# show mpls ldp neighbor


Semoga bermanfaat..............trims
