Question

vrf routing on cisco switch

Asked by: FalconQ

Hello,

I have a simple problem-question. Take a look on the config below, the problem is that I cannot do following ping:

ping from the outside to 80.80.80.222 ok
ping from the outside to 80.80.129.130 ok via vrf Test_1
ping from the outside to 80.80.129.130 fails via vrf Test

the ip address 80.80.129.130 is only reachable via 80.80.80.221
trough the interface vlan 200 because this is the only "link net" to next hop....

Do I need to change the "rd" on the VRF instances in order to make this routing possible ??
When I say change the RD I mean make it possible for these 2 vlans to communicate with each other which is not possible with this configuration.

So the point of the question was do I need to enable the configuration between these 2 vlans in order to make the routing possible from one vlan trough the another ?

Config below:

ip vrf Test
 rd 65225:1002
 route-target export 65225:1002
 route-target import 65225:1002
!
ip vrf Test_1
 rd 65225:1001
 route-target export 65225:1001
 route-target import 65225:1001
!
interface Vlan200
 description ** Test_1 **
 ip vrf forwarding Test_1
 ip address 80.80.80.222 255.255.255.252
 no ip redirects
 no ip unreachables
 no ip proxy-arp
!
interface Vlan100
 description ** Test **
 ip vrf forwarding Test
 ip address 80.80.80.225 255.255.255.224
 no ip redirects
 no ip unreachables
 no ip proxy-arp
!
ip route vrf Test 0.0.0.0 0.0.0.0 80.80.80.221
ip route vrf Test_1 0.0.0.0 0.0.0.0 80.80.80.221

Since each vlan is in its own routing table the only ways you can get communication is to either import the other vlan's RD. If you really wanted to keep things seperate you could use a transit device that connects one vlan to the other.
