ip route-export 2:2
ip route-import 1:1 import_ospf_protocol
!this action accepts only OSPF routes from VRF-red even though both OSPF as well as BGP
routes are shared
The show VRF commands displays the following output:
DellEMC# show ip route vrf VRF-Blue
C 122.2.2.0/24 Direct, Te 1/22/1 0/0 22:39:61
O 22.2.2.2/32 via 122.2.2.2 110/0
00:00:11
O 44.4.4.4/32 via vrf-red:144.4.4.4 0/0 00:32:36
<< 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.
