Định nghĩa giao diện Tunnel
Với MX series cần enable tunnel services
set chassis fpc 0 pic 0 tunnel-services bandwidth 10g
# vMX1
set chassis fpc 0 pic 0 tunnel-services bandwidth 10g
set interfaces gr-0/0/0 unit 0 tunnel source 1.1.1.1
set interfaces gr-0/0/0 unit 0 tunnel destination 3.3.3.3
set interfaces gr-0/0/0 unit 0 family inet
# vMX3
set chassis fpc 0 pic 0 tunnel-services bandwidth 10g
set interfaces gr-0/0/0 unit 0 tunnel source 3.3.3.3
set interfaces gr-0/0/0 unit 0 tunnel destination 1.1.1.1
set interfaces gr-0/0/0 unit 0 family inet
Định nghĩa tuyến đường
# vMX1
set routing-options static route 192.168.2.0/24 next-hop gr-0/0/0.0
# vMX3
set routing-options static route 192.168.1.0/24 next-hop gr-0/0/0.0
Kiểm tra
- Kiểm tra trạng thái interface gr
root@vMX1> show interfaces gr-0/0/0 terse
Interface Admin Link Proto Local Remote
gr-0/0/0 up up
gr-0/0/0.0 up up inet
root@vMX3> show interfaces gr-0/0/0 terse
Interface Admin Link Proto Local Remote
gr-0/0/0 up up
gr-0/0/0.0 up up inet
- Kiểm tra route
root@vMX1> show route 192.168.2.0
inet.0: 10 destinations, 10 routes (10 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

> via gr-0/0/0.0
root@vMX3> show route 192.168.1.0
inet.0: 10 destinations, 10 routes (10 active, 0 holddown, 0 hidden)
