Skema sederhana router untuk  BGP dan MPLS

KONFIGURASI IP ADDRESS

PE_1    : 192.168.1.1/24 -> e1/0

PE_2    : 192.168.3.2/24 -> e1/0

LSR_1 : 192.168.1.2/24 -> e1/0

            : 192.168.2.1 /24-> e1/1

LSR_2 : 192.168.2.2 /24-> e1/0

            : 192.168.3.1/24 -> e1/1

Command Line : contoh PE_1

router (config)# interface ethernet 1/0

router (config-if)# ip address  192.168.1.1 255.255.255.0

router (config-if# no shutdown

KONFIGURASI IP INTERFACE LOOPBACK

LSR_1 : 192.168.100.2/32

LSR_2 : 192.168.100.3/32

PE_1 : 192.168.100.1/32

PE_2 : 192.168.100.4/32

Command Line : contoh PE_1

router (config)# interface loopback 0

router (config-if)# ip address  192.168.100.1 255.255.255.255

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_1

# router ospf 100

# network 192.168.2.0 0.0.0.255 area 100 -> core

# network 192.168.3.0 0.0.0.255 area 100 -> PE_2

# network 192.168.100.2 0.0.0.0 area 100 -> loopback core

CEK ROUTING

Periksa router

# show ip route

Mencoba Ping dari PE_1 Ke LSR_1

# ping 192.168.1.2

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 1/0 -> connect ke LSR_1

# ip address 192.168.1.1 255.255.255.0

# 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 192.168.3.2 255.255.255.0

# 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 192.168.1.2 255.255.255.0

# 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 192.168.2.1 255.255.255.0

# 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 192.168.2.2 255.255.255.0

# 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 192.168.3.1 255.255.255.0

# mpls ip

Cek Status MPLS

# show mpls ldp neighbor
