Hi,
Am trying to use VRF-Lite Route leaking , but am able to import/export routes between two vrfs. Ping is working within VRF to/from hosts , but am not able ping between two nodes.(Server/Host). Configuration/toplogy is mentioned below for feedback.

Hi @uni1389 ,
You need to configure BGP for the import/export to work. Here's a simple configuration of how it should be configured:
router bgp 111
address-family vpnv4 unicast
!
vrf WHITE
address-family ipv4 unicast
redistribute connected
vrf BLUE
address-family ipv4 unicast
redistribute connected

Thanks Harold,
can we do it without BGP instance, like with static route.

Hi @uni1389 ,
Yes, it is certainly possible to use static routes to achieve the same:
router static
vrf BLUE
address-family ipv4 unicast
192.168.11.0/24 vrf WHITE GigabitEthernet0/0/0/1
!
!
vrf WHITE
address-family ipv4 unicast
172.16.20.0/24 vrf BLUE GigabitEthernet0/0/0/0
