Virtual Route Forwarding (VRF) - simple config - ping won't work from PC, but ok from R1

[Ivan Mamka]

Hello,

I might be missing some basics on how VRFs work. But Following is configuration GNS3 (question at the bottom, image attached):

PC4 -->(G2/0) R1 (G1/0.2)---> (G1/0.2) R2

PC4: ip 10.1.1.10 255.255.255.0 10.1.1.1 

R1:

vrf definition sony
address-family ipv4

int g1/0.2
vrf forwarding sony
encapsulation dot1q 2
ip address 105.1.1.1 255.255.255.252
ip ospf 2 area 0
ip ospf network point-to-point
no shutdown

int gig2/0
vrf forwarding sony
ip address 10.1.1.1 255.255.255.0

no shutdown

R2:

int gig1/0.2
encapsulation dot1q 2
vrf forwarding sony
ip address 105.1.1.2 255.255.255.252
ip ospf network point-to-point
ip ospf 2 area 0
no shutdown

PC1: pint 10.1.1.1    <--- OK

PC1: ping 105.1.1.1 <--- OK

PC1: ping 105.1.1.2 <--- ICMP timeout

R1: ping vrf sony 105.1.1.2   <---- OK

Question: Why I can't ping interface of R2 from PC1 but I can ping it from R1?

Thought: If ICMP timeout means R1 has path to route but R2 not replying?

Thanks!:)

Hi,

Is your OSPF up between R1 and R2? Or do you have any static route on R2 to reach out back the subnet 10.1.1.0/24 residing on R1?

Your 10.1.1.0/24 seems not being part of your OSPF, are you doing any redistribute connected?

Can you share the routing part of your config and also the output of (on all routers):

- sh run | s r o

- sh ip ospf nei

- sh ip route vrf sony
