For BMP route monitoring, allows you to excludes routes that are non-eligible for the decision process (for example, protocol nexthop not resolved). This represents the view of the BGP routes after running the import policy. If the import policy has rejected the BGP route, the route does not exist in the post policy view.
If post-policy is configured the router applies the import policies on the routes received so that BMP can display the routes as follows:
If an import policy modifies any parameters in the route, the route is displayed by BMP with the new values.
If an import policy modifies the NH and the NH is unresolved by the local router, the route is displayed by BMP as reachable.
If an import policy rejects a route, it is displayed as unreachable in BMP update.
If a route is received with unreachable NH, but the import policy doesn't reject the route, then BMP displays the route as reachable.
Using post-policy with exclude-non-eligible causes an unreachable BMP update in the following:
If an import policy modifies the NH and the NH is unresolved by the local router, the route is displayed by BMP as unreachable.
if a route is received with a NH that is unreachable, and the import policy does not reject this route, it is displayed by BMP as unreachable.
If you have initially configured post-policy route monitoring, but later delete the initial configuration and configure pre-policy route monitoring, then the previously advertised post-policy routes are withdrawn. Conversely, if you have initially configured pre-policy route monitoring and later modify it to post-policy route monitoring, then the previously advertised pre-policy routes are withdrawn.
