A route unmodified by the inbound policy on a monitored router is included both in Pre-Policy Adj-RIB-In as well as Post-Policy Adj- RIB-In Route-Monitoring messages when both the Pre-Policy and Post- Policy Route-Monitoring modes are enabled. Similarly, a route unmodified by the outbound policy is included in Pre-Policy Adj-RIB- Out as well as Post-Policy Adj-RIB-Out Route-Monitoring messages.
