Day 94 of 100DaysOfHomeLab

Day 94 of 100DaysOfHomeLab and I have been playing with OSPF, GRE Tunnels, Mikrotik, Bird and ECMP.

  • I got 2 GRE tunnels setup between the MikroTik box and my DEC-IX box (Debian running Bird).
  • OSPF running and announcing stuff over those 2 links, plus the original Wireguard Link.
  • ECMP enabled over all 3 links!
  • IPv4 traffic seems to be sent between the 3 links!
  • IPv6 traffic still only going over the single Wireguard link…

I am reading up on OSPF v3 (v2 is for IPv4 traffic) and trying to figure out how to get it running. So far, no luck… Getting so close to it though.

Whats the end game? both WAN links connected to all 3 of my upstream servers (Vultr, VMHaus and DEC-IX box) allowing more stable connections and more bandwidth (hopefully…)

Next week I am OOHL (Out Of Home Lab…) but will still try do a bit of work. Fingers crossed!


My name is Tiernan OToole, and I run my own ASN, AS204994. More details about that over there. I also use Vultr for transit services and HostUs for LIR Services. Check them out. You can also check some of the gear I use on a daily basis over on If you find this stuff useful, you could also Buy me a coffee! Thanks!
