Virtual Routing and Forwarding (VRF) would appear to be a perfect companion for a router device, considering its benefits
-
higher priority ip rules (Policy Based Routing, PBR)
-
iproute2 supports the vrf
-
unix socket routing
-
impacts only Layer 3 and above so L2 tools (e.g., LLDP) are not affected
-
VRF devices allow VRFs to be nested within namespaces
Unfortunately, support for VRF is currently absent from the OpenWRT repo in all version.
