Hi Team,
I was trying to configure rtt in a route-map set metric option but VyOS doesn’t allow it or at least is not available in the help in the cli.
http://docs.frrouting.org/en/stable-8.3/routemap.html#clicmd-set-metric-1-4294967295-rtt-rtt-rtt
This is a great way to set the med depending on the rtt.
