Dynamic Route Leaking
Route Leaking is a powerful feature that enables communication between isolated (virtual) routing domains by segregating and
sharing a set of services such as VOIP, Video, and so on that are available on one routing domain with other virtual domains.
Inter-VRF Route Leaking enables a VRF to leak or export routes that are present in its RTM to one or more VRFs.
Previous FTOS releases support static route leaking, which enables route leaking through static commands. Dynamic Route
Leaking, introduced in the 9.7(0.0) release, enables a source VRF to share both its connected routes as well as dynamically
learnt routes from various protocols, such as ISIS, OSPF, BGP, and so on, with other default or non-default VRFs.
You can also leak global routes to be made available to VRFs. As the global RTM usually contains a large pool of routes, when
the destination VRF imports global routes, these routes will be duplicated into the VRF's RTM. As a result, it is mandatory to use
route-maps to filter out leaked routes while sharing global routes with VRFs.
