Test Connection With Next Hop IPv6

Description

Tests connection between two devices with BFD in static routes using the gateway as the BFD peer, checking if they are each others peers and their status is up and installed.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address '3fff:10::100/64'
set protocols static route6 '::/0' next-hop '3fff:10::200' bfd
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address '3fff:10::200/64'
set protocols static route6 '::/0' next-hop '3fff:10::100' bfd
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
