LDP (Label Distribution Protocol) adalah suatu procedur yang digunakan untuk mendistribusikan ikatan label yang terlah dibuat dari satu LSR ke LSR lainnya dan juga sebagai pengatur jalan yang dynamis dalam satu jaringan MPLS. LDP adalah penlabellan secara dynamic/otomatis yang sudah diatur oleh mikrotik itu sendiri.`didalam arsitektur jaringan MPLS sebuah LSR yang merupakan tujuan/hop selanjutnya akan menginformasikan tentang ikatan sebuah label ke LSR yang sebelumnya mengirimkan pesan untuk mengikat label tersebut bagi rute paketnya.
Pada lab kali ini kita akan mempelajari bagaimana suatu label akan ditentukan dan diberi secara otomatis.
Untuk topologinya seperti ini :
#konfigurasi nama
[admin@MikroTik] > system identity set name=R1
#konfigurasi loopback
[admin@R1] > interface bridge add name=loopback
[admin@R1] > ip address add address=1.1.1.1/32 interface=loopback

Cek pada LDP neighbor apakah sudah aktif atau belum ? Dengan perintah :
[admin@R3] > mpls ldp neighbor print detail
