Hello,

I am quite puzzled with the issue I am having. In my test, I had route-leaking setup. Saved the configurations and turned off the router. Next time I boot up the routers, my route-leaking isn't working.

Problem:
1) Computer VRF cannot ping any 10.1.0.0/30 or 10.1.0.4/30 IP address.
2) Servers VRF cannot ping any 10.1.0.0/30, 10.1.0.4/30, 10.2.0.0/30 or 10.2.0.4/30 IP address.
3) Wi-Fi VRF cannot ping any 10.2.0.0/30 or 10.2.0.4/30 IP address.

I am pretty sure I am not messing anything. Also, I tried re-doing BGP, but once I deleted the BGP and re-add the same commands, BGP wouldn't work anymore. I had to reload the router to fix that issue. Any help would be greatly appreciated. Thank you!

Hey,

We've done a private troubleshooting session.

We've issue the command ip routing protocol purge interface to force a purge of the RIB for interface going down. We've shutted down ospf neighbor with ASA firewall to be sure that there wasn't any issue related with ASA.

Everything works perfectly. Bring back ASA, add route-map to redistribute specific subnets on different ospf process with ASA.

Thanks

Hi

Please let me check the config, also do you have a diagram?

Julio,

I can attach a topology for you.

Francesco Molino · ‎05-28-2017

Hi

Just a quick follow-up. I don't know if you get in touch with Julio already for your question but here are my remarks.

Your loopbacks from different vrf shouldn't be reachable from External as the routing (static route in your case) are not configured for those loopbacks.

Could you give us some output of what isn't working exactly ?

Can you please add output of your different sh ip bgp (global and vrfs) ?

Viewing your config, it was clear that everything was ok however to be sure and test what you mentioned I built a quick lab and it works. (here a quick screenshot of a ping from vrf Servers):

Nothing on my end pings. There's no ACL or anything blocking it. The confusing part about it to me is that like I mentioned in my first statement I turned my router off for the night (saved) and the next morning it wouldn't work anymore... With the same configurations. Doesn't make much sense to me.

Francesco Molino · ‎05-29-2017

Hi

Stupid question but I assume that all your interfaces are UP.

When you're doing your pings. have you done a debug ip icmp on the other side? If yes, do you see packets arriving?

The config you posted are the right ones? I mean is there any additional config like NAT? I know you said there isn't any ACL.

Can you do a traceroute to see where the packets are going?

Let's concentrate on this ping that's not working:

ping vrf Servers ip 10.2.0.5 source 10.71.0.17

On your internal_router, from which you're initiating ICMP packets, could you run a debug before sending those pings:

access-list 100 permit ip host 10.71.0.17 host 10.2.0.5
access-list 100 permit ip host 10.2.0.5 host 10.71.0.17

debug ip packet 100 detail

Hi

When you did the debug, did you configured the acl? Because i see some traffic for protocol 89 that's ospf and normally we shouldn't see it.

Can you please do again the debug and put the output into a text file? It will be better to read it through my mobile device.

Can you do a show ip ospf neighbor and show ip route?

It looks like you have a routing loop.

Thanks

Francesco,

I've attached the debugging in notepad for you. I also did the route/ospf from both sides.

Francesco Molino · ‎05-30-2017

Hi

Just a quick question before I review all informations. Why on your external router you've 4 OSPF peering? You should have only 2 like your internal router:

External_Router#show ip ospf neigh

Neighbor ID     Pri   State           Dead Time   Address         Interface
10.255.255.253    1   FULL/DR         00:00:37    10.2.0.6        GigabitEthernet0/0.1200
10.255.255.255    1   FULL/DR         00:00:31    10.2.0.1        GigabitEthernet0/1.1200
10.255.254.253    1   FULL/DR         00:00:32    10.1.0.6        GigabitEthernet0/0.1100
10.255.254.255    1   FULL/DR         00:00:31    10.1.0.1        GigabitEthernet0/1.1100

Thanks

The packet is leaving the vrf Servers but we don't see it coming back. You should see something like s=10.2.0.5, d=10.71.0.17 in your debug output but nothing is there.

Can you run the command sh ip cef 10.71.0.17 internal on your external router?

Thanks

Thanks
Francesco

Shawnw4401 · ‎05-30-2017

Francesco,

There's four in the external router because it is learning a route from an ASA as well. That's where it is learning the route about 10.1.0.1 and 10.2.0.1.

Shawnw4401 · ‎05-30-2017

Francesco,

External_Router#sh ip cef 10.71.0.17
10.71.0.16/28
nexthop 10.1.0.6 GigabitEthernet0/0.1100
nexthop 10.2.0.6 GigabitEthernet0/0.1200

Francesco Molino · ‎05-30-2017

It's weird.

I'm reviewing the case logs but i don't see the debug ip icmp of your external router when you initiate a point from your internal router. Can you do this trace?

And after that, instead of debug ip icmp, can you run debug ip packets with same acl as before?

Your routing seems OK. While you send us these news logs in a text file I'll review previous logs to make sure i didn't missed something.

Stupid question, when you faced that issues did you reboot your routers right away?

If you can, are you able to setup a Wireshark capture on your internal router for the interface facing your external router?

Because on previous debug we saw that the packet was leaving the vrf Servers but no incoming packets seen in this capture. I want to make sure your external router is sending back the reply.

Thanks

Thanks
Francesco

Shawnw4401 · ‎05-30-2017

Francesco,

I have never really used wireshark... something I wanted to learn more about in later uses. If you would be able to walk me through it (if not too much trouble) I'd gladly be able to get you that.

After I boot the lab--the next morning--I restarted the lab again after finding out the configurations aren't working for some reason. After that didn't work, that is when I started trying to troubleshoot it.

Give me a moment to turn on my lab and I'll post the debug for you.

Route leaking issues?
