Symptom

When configuring LISP route-import with a route-map that references an "ip as-path access-list", changes to the access list will not trigger a re-evaluation of pre-existing RIB routes.

Conditions

Router configured as a Locator Identity Separation Protocol (LISP) xTR using the LISP route-import configuration with a route-map that references an as-path access-list.

Workaround

After modifying the configuration of the as-patch access-list, force a re-evaluation of LISP route import through the "clear ip lisp instance-id route-import" command.
