This is openwrt running lede on a x86-64 VM and the current openwrt 
babel package wit h version 1.8 connecting to a debian server using 
fastd. the fastd-interface called mesh-vpn is one of babels interfaces.
On the server I have babeld-1.7.1-71-g556af3c installed.

This is the server-side configuration of babeld:
Ipv6-subtrees true
Export-table 10
Import-table 11
Import-table 12

Interface mesh-vpn-1312
Interface eth2
Redistribute metric 256


On the openwrt-VM I am running this config:
ipv6-subtrees true
Export-table 10
Import-table 255
Import-table 11
Redistribute ip 2a06:8187:fbab:2::1/128 deny
Redistribute ip 2a06:8187:fbab:2::/64 eq 128  allow
Redistribute ip 2a06:8187:fbab:1::/64 eq 128  allow
Redistribute local  deny
Redistribute ip ::/0 eq 0  allow

Babeld is started on interface "lo" where there is no real traffic but 
babeld insists on starting with an interface. The interface mesh-vpn 
(fastd-interface) is added via add interface on the socket during fastd 
runtime.


It seems sometimes rtt is reported and sometimes it is not and I cannot 
quite identify what causes it to be visible.
