Hi Fellas, we have a working PBR in an ACI Multi site setup. The ACI is re-directing some East-West EPG traffic to the local DCFW using PBR/contracts. There is some new requirement that has come up to stretch a BD across the 2 sites, due to which I need to introduce host-based routing to keep traffic symmetry. (Otherwise the local DCFW will drop traffic due to a-symmetric flow).
My Question here is: if the VRF sees a host-based route (/32) been learnt from the ISN L3Out and that host route is also a part of the bigger subnet (/24) created on the EPG used for PBR, then what traffic flow am I going to be encountering here? Will the traffic be PBR`d for the host based route or will it follow its regular routing?
Example:
src-epg-subnet-a-/24 to dest-epg-subnet-b-/24 is working using PBR.
src-epg-subnet-a-/24 to host-based-route that is part of dest-epg-subnet-b-/24. ------? What is expected??
Thx
