Saya mengalami masalah menaikkan VPLS menggunakan ME3600x dengan 15,3 (2) dan pensinyalan BGP. @yelfathi dan @packettalk telah mengarahkan saya ke rute yang benar tetapi tidak yakin bagaimana mengatasinya.
Saya memiliki 2 switch ME3600 menggunakan RSVP sebagai PE dan 2 router MX80 sebagai P.
Router P menunjukkan LSP sebagai LSP transit dengan benar dan terowongan TE saya naik. Pada kedua switch saya mendapatkan yang berikut: -

setelah beberapa bantuan dari @ytti kami telah mempersempitnya menjadi bug dalam me3600 tentang pensinyalan BGP.
Kami mengubah pensinyalan menjadi LDP dan berfungsi dengan baik. Akan memposting pembaruan setelah diselesaikan dengan Cisco.
nvm, saya melewatkan fakta bahwa LSP naik
Maaf. tidak yakin bagaimana cara mengurutkan pemformatan

stackexchange tampaknya tidak sempurna untuk masalah jenis ini. Tapi sepertinya ME3600 berpikir ada masalah pada label IGP Anda (yaitu terowongan RSVP). Mungkin detail 'sh ip cef 46.226.0.10' akan membantu (ikuti label hop-by-hop dan post output untuk kedua arah). Juga mungkin mencoba mengurangi domain bermasalah, dengan mencoba label IGP di 'LDP' terlebih dahulu (pertahankan VPLS di BGP). Hal lain yang bisa Anda coba, adalah mengkonfigurasi L3 MPLS VPN pada loopbacks dari ME3600, untuk melihat apakah ada masalah. Saya ingin melihat BGP NLRI juga, meskipun mereka mungkin baik-baik saja karena Anda memiliki label VPN.

Hai Ytti. Ada 2 MX80 menengah. Akan melihat itu juga.
