Two unrelated agency VRFs accidentally share the same route target import/export values. What is the likely result?
Select an answer to reveal the explanation.
Short Explanation
Shared RTs are shared club membership cards—suddenly both agencies get each other's routes. That accidental merge is how multitenancy dies quietly while configs still look 'almost right.' Keep RT hygiene as strict as badge access.
Full Explanation
Route targets control which VPN/EVPN routes are imported into a routing instance. Reusing RTs across unrelated tenants causes unwanted route exchange and logical merger of isolation domains. That is an RT hygiene failure, unrelated to UDP port randomization, underlay BFD admin-down, or IRB MAC loss. Assign and document unique RT sets per tenant unless an extranet is intentional.
