Hello Cisco Community,
I'm currently working on a deployment scenario where I’m testing a two-arm Service Graph with Policy-Based Redirect (PBR) for both East-West and North-South traffic in multipod architecture and i have separated Active \ standby cluster for each POD. The setup involves two VDOMs, one dedicated to East-West and the other to North-South inspection.
I'm facing some design challenges and would appreciate your insights.
When referring to one-arm or two-arm, are we speaking about physical interfaces or logical (sub)interfaces?
I'm considering using a single vPC shared between the two VDOMs, with separate VLANs per VDOM (e.g., VLAN XX for East-West and VLAN YY for North-South).
Is this a valid and recommended approach, and will it work in practice?
In the case of two-arm mode, from an ACI perspective, is it required to have two separate physical interfaces (one for ingress, one for egress), or is it acceptable to use subinterfaces (SVIs/VLANs) on the same physical vPC link?
Thank you in advance for your support and guidance.
