In order to support MTR, we worked hard as well to design our ASIC in catalyst 6500 family. ☺ That feature is very ASIC resource demanding and I think that was latest HW piece can do MTR forwarding.
Without ASIC that can support MTR in the industry now, could Jafar share something with us why we need to develop MTR routing? My personal believe is that with the introduction of source based routing scheme recently ( such as segment routing), MTR may be easier to be supported in the network end-to-end that way.

The "official" term for that is Multi-Topology (MT) Routing in OSPF which is described in RFC 4915 (https://tools.ietf.org/html/rfc4915). After some digging I found that this was actually brought up 6 years ago on this list: https://lists.quagga.net/pipermail/quagga-dev/2009-July/006789.html And It seems like there was a collective effort to get this up and running with progress on github here: https://github.com/tomhenderson/quagga-mtr/ I see names like Paul, Vincent, Joakim among others who had contributed to this effort. I haven't checked to see how far did this go but it seems nobody has touched it in 5 years. Multi routing table support was not very common at the time in Linux kernels, and the same can be said about VRF which are things that could have hindered the move at the time but I'm not sure. Can anyone tell me please about that project or any similar efforts? Somewhat related...didn't cisco eventually abandon MTR? I remember them dumping huge resources into this but if my memory is correct the whole project was cancelled (from googling it looks like it did ship though) Daniel _______________________________________________ Quagga-dev mailing list [email protected]<mailto:[email protected]> https://lists.quagga.net/mailman/listinfo/quagga-dev
