Good morning,
I need to insert a route in the general routing table and in a VRF.

Reading on Internet,
I thought to use ip vrf receive command on the interface.



this is CS router :

hostname CS
!
boot-start-marker
boot-end-marker
!
ip cef
!
!
!
!
ip vrf VTC
!
interface Loopback1021030
 ip vrf receive VTC
 ip address 10.210.3.1 255.255.255.255
 ip policy route-map PC_TO_VTC
!
interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
!
interface FastEthernet0/1
 ip vrf receive VTC
 ip address 10.210.0.6 255.255.255.252
 ip policy route-map PC_TO_VTC
 speed auto
 full-duplex
!
!

!
ip forward-protocol nd
ip route vrf VTC 10.208.0.0 255.255.255.0 10.210.0.5
!
!
no ip http server
no ip http secure-server
!
access-list 100 permit ip 10.210.3.0 0.0.0.255 10.208.0.0 0.0.0.255
access-list 100 permit ip 10.208.0.0 0.0.0.255 10.210.3.0 0.0.0.255
access-list 100 permit ip 10.210.0.0 0.0.0.255 10.208.0.0 0.0.0.255
access-list 100 permit ip 10.208.0.0 0.0.0.255 10.210.0.0 0.0.0.255
!
route-map PC_TO_VTC permit 1
 match ip address 100
 set vrf VTC

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!


and this is border router :


hostname Border_VTC
!
boot-start-marker
boot-end-marker
!
!
no aaa new-model

ip cef

ip vrf VTC

interface Loopback1
 ip vrf forwarding VTC
 ip address 10.208.0.1 255.255.255.255
!
interface FastEthernet0/0
 ip vrf forwarding VTC
 ip address 10.210.0.2 255.255.255.252
 duplex auto
 speed auto
!
interface FastEthernet0/1
 ip vrf forwarding VTC
 ip address 10.210.0.5 255.255.255.252
 speed auto
 full-duplex

ip forward-protocol nd
ip route vrf VTC 10.210.3.0 255.255.255.0 10.210.0.6
