Jia - The concept of a logical router( or virtual router) is closely tied(mirrored) to linux namespaces concept. Currently if you want complete process separation I would suggest creating a name space and running separate instances of FRR in it( look at the startup options to point FRR at different locations for config and runtime files to do this ) If you want to run one instance of FRR across multiple namespaces there would need to be work done here, but is possible. donald On Thu, Jun 28, 2018 at 8:24 PM, Jia Chen <jchen1@paloaltonetworks.com> wrote:
Hi Donald,
Thank you! Please refer to response inline. (<<<JAY).

A) OSPF v2 supports both MI and VRF's. Use one or the other, but not
at the same time. No-one has done the work to make IS-IS vrf aware at
this point in time(patches welcome! HA!)
(<<<JAY) Ok I will add IS-IS to the to-do-list which needs work to support MI and VRF’s.
For B, I am not really quite sure what you are asking. I guess that
you are asking does FRR support l3vpn's and EVPN in a VRF context and
yes it does.
(<<<JAY) Yes, (b) means VPN VRF
For C, I do not understand your question.
(<<<JAY) Contrast to (b), non-VPN routing instance; Does FRR VRF support both cases, may be the context tell the difference?

As for logical router, just create linux namespaces and run separate
instances of FRR.
(<<<JAY) OK.
