Mungkin wes pernah weruh utowo krungu seng jenenge GNS3 sebagai emulator produk cisco, bedo meneh karo juniper, produk juniper ra nganggo software emulator ngunuinan. Amargo juniper wes duwe fitur dewe yoiku seng jenenge logical router utowo luweh dikenal neng njero router enek router.
Logical router iku yo support sembarang fungsi router juniper. semisal fungsi routing, OSPF, BGP, EIGRP lan laine. Pokoke meh mirip plek mbek an router juniper.
Nanging Logical router mung iso digawe mentok 15 router. Oke nyambung neng pembahasaan.

Iki proses gawe logical router neng Router Juniper. Aku arep gawe 3 logical router.

Konfigurasi interface logical router R1, r2 dan r3

randy# edit logical-routers r1
randy# set interfaces em1 unit 1 vlan-id 10 family inet address 192.168.1.1/24

randy# top edit logical-routers r2
randy# set interfaces em2 unit 1 vlan-id 10 family inet address 192.168.1.2/24
randy# set interfaces em3 unit 1 vlan-id 20 family inet address 10.10.10.2/24

randy# top edit logical-routers r3
randy# set interfaces em4 unit 1 vlan-id 20 family inet address 10.10.10.1/24

Konfigurasi static route r1
randy# edit logical-routers r1
randy# set routing-options static route 192.168.1.0/24 next-hop 10.10.10.2
randy# set routing-options static route 10.10.10.0/24 next-hop 192.168.1.2

Konfigurasi static route r2
randy# edit logical-routers r2
randy# set routing-options static route 10.10.10.0/24 next-hop 192.168.1.1
randy# set routing-options static route 192.168.1.0/24 next-hop 10.10.10.1

Konfigurasi static route r3
randy# edit logical-routers r3
randy# set routing-options static route 10.10.10.0/24 next-hop 10.10.10.2
randy# set routing-options static route 192.168.1.0/24 next-hop 10.10.10.2

Bar iku langsung setting vlan-tagging
randy# set interfaces em1 vlan-tagging
randy# set interfaces em2 vlan-tagging
randy# set interfaces em3 vlan-tagging
randy# set interfaces em4 vlan-tagging

trus di apply
randy# commit

nah wes bar proses gawe logical routere, bar iku proses verifikasi. Nah verifikasine pastike R1 karo R2 iso saling ping.
