<< only OSPF and BGP leaked from VRF-red
Important Points to Remember
• Only Active routes are eligible for leaking. For example, if VRF-A has two routes from BGP and OSPF, in which the BGP route is not
active. In this scenario, the OSPF route takes precedence over BGP. Even though the Target VRF-B has specified filtering options to
match BGP, the BGP route is not leaked as that route is not active in the Source VRF.
• The export-target and import-target support only the match protocol and match prefix-list options. Other options that are configured
in the route-maps are ignored.
• You can expose a unique set of routes from the Source VRF for Leaking to other VRFs. For example, in VRF-red there is no option for
exporting one set of routes (for example, OSPF) to VRF- blue and another set of routes (for example, BGP routes) to some other
VRF. Similarly, when two VRFs leak or export routes, there is no option to discretely filter leaked routes from each source VRF.
Meaning, you cannot import one set of routes from VRF-red and another set of routes from VRF-blue.
