In a CRB design, inter-subnet traffic for a VLAN fails and the spine has no IRB for that VLAN. What configuration check aligns with the architecture?
Select an answer to reveal the explanation.
Short Explanation
CRB expects the gateway upstairs on the spine — if that IRB is missing for the VLAN, inter-subnet dies. Check spine/border IRB placement against the design, do not relocate everything to ERB leaves by accident.
Full Explanation
CRB places tenant IRB/default-gateway functions on spines or border devices. Missing IRB (and associated L3 context) for a VLAN breaks inter-subnet forwarding for that tenant segment. Align configuration with CRB intent rather than forcing leaf-only IRBs, removing Type-1, or bridging via the underlay IGP without VXLAN.
