Hello everyone,

I have a problem due to VRF issue. If anyone can find me a solution I would appreciate it. I am sending my current configuration in brief to check:

So here is the explanation:

My gig 0/1/0 and gig 0/1/1 ports are connected to PE router and I am configuring the CE router. There is no problem on bgp I can ping vrf to the Interface of PE routers. What the problem is on my 0/0/1 port it will be connected to my local Lan. IP routes will further be added but what I am trying to do is I am giving my computer as the IP of 57.235.205.181/28 for example and I can ping the Routers interface of Gig 0/0/1.2 which is 57.235.205.177. However on the Router I can't ping to the address of computer. What is more surprising is I can't even ping to the it's own IP address on the router itself. When I remove the command Vrf forwarding PENS_MSG_OPS from subinterface 0/0/1.2 for example this time I can ping the computer but I can't ping the IP VRF on the PE router side from my router. What am I missing here? what kind of change should I make to ping both of them? If you can help me I will appreciate it. Thank you for your helps, have a nice weekend.

Hello,

does the original post have the full configuration of the router ? Take all the unused and incomplete parts out. Is there anything else left in the service policy ?

Hello,

the classes in your service policy do not have any action defined.

Take the entire service policy off the interface, also the HSRP stuff, so it should look like this:

interface GigabitEthernet0/0/1.2

description PENS_MSG_OPS

encapsulation dot1Q 2

vrf forwarding PENS_MSG_OPS

ip address 57.235.205.177 255.255.255.240

adergah · ‎12-16-2017

HSRP does work because I have a standby router as you can see in the configuration. And I don't see any relation between service policy and not being able to ping the computer. Thank you for your helps.

mattjones03 · ‎12-16-2017

Hi,

It does sound like it’s a case of your Windows firewall being enabled.

With the Windows firewall temporarily disabled, does this correct the issue?

adergah · ‎12-16-2017

It is definetely not firewall problem of Windows. I tried 3 different computers one with Linux. And it didn't work.

Georg Pauwen · ‎12-16-2017

Hello,

can you ping with the HSRP standby address, 57.235.205.178, as the source ?

ping vrf PENS_MSG_OPS 57.235.205.181 source 57.235.205.178 ?

And vice versa, can your PC/computer ping 57.235.205.178 Your PC/computer needs to have 57.235.205.178 as the default gateway, make sure that is configured...

adergah · ‎12-16-2017

I am off at the work for today. Tomorrow night I will be able to do these steps and I will inform you about the results. Thank you for your helps and supports. Have a good weekend.

adergah · ‎12-17-2017

So here is the last situation:

Right now I can ping vrf 57.235.205.181 from the router,

I can ping 57.235.205.177 and standby address 57.235.205.178 from the computer.

Just I can't ping 57.235.205.181 without vrf from the router.

Is this a normal situation in my case?

Georg Pauwen · ‎12-17-2017

Hello,

--> I can't ping 57.235.205.181 without vrf from the router.

That is the to-be-expected behaviour. The entire subnet is part of the VRF, so only reachable within the VRF.

adergah · ‎12-17-2017

Problem seems to be solved. Thank you very much for your helps and supports.

Best regards,
