How to import VRF route-table to Global route-table

[tianwen.zhao]

Hi everyone,

How to import VRF route-table to Global route-table

For example:

R1#sho ip route
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

12.0.0.0/24 is subnetted, 1 subnets
C 12.1.1.0 is directly connected, FastEthernet0/0

R1#sho ip route vrf A

Routing Table: A
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

13.0.0.0/24 is subnetted, 1 subnets
C 13.1.1.0 is directly connected, FastEthernet0/1

I want the global route-table have subnet 13.1.1.0/24  and VRF A route-table have 12.1.1.0/24 too..

I know the VRF route-table can import each other ,but How to import VRF route-table to Global route-table?

Thank you

You could use static routes or import maps depending of what kind of vrf you are running.
Below is a example of vrf -lite  route into global rib and global rib into vrf table also it you runing any IGP then naturally the vrf route will also need to be advertised into that for remote reachability.

ip route 13.1.1.0 255.255.255.0 fastethernet 0/1
ip route vrf A 12.1.1.0 255.255.255.0 (nexthop ip address) global

Thank you for your reply.

Could you please also tell me how to use import maps ?

Thank you so much

Hello
VRF import/export maps

ip prefix-list GlobalRoute permit 12.1.1.0/24
ip prefix-list VRFroute permit 13.1.1.0/24

route-map intoVRF
match ip address prefix-list GlobalRoute

route-map intoGlobal
match ip address prefix-list VRFroute

Ip Vrf A
rd x:x
import ipv4 unicast map intoVRF
Export ipv4 unicast map intoGlobal
