Problem:
For a school project I have to configure a rather unconventional network. The original given topology was a bit simpler, but because we have to simulate the devices with EVE-NG we lost the ability to stack devices. So instead of stacking our Core and Distribution switches, we get the mess below.
I managed to get the layer 3 link-aggregation between the Core- and Distribution layer switches running and I also configured GLBP for all the Distribution Switches, but I'm still unable to ping between PCs in different VLANS. Pinging between PCs in the same VLAN seems to work just fine, even if they are connected to different access switches. The PCs are also able to ping to the virtual GLBP default gateway address of their respective VLAN. The Native VLAN is 1, and all the links between the Access and Distribution switches are in trunking mode. The Access switches' ports going to the PCs are configured in access mode for a specific VLAN. The Layer 3 Distribution switches are able to ping to the IPs of all the PCs regardless of their VLAN.
I have the feeling I'm missing something obvious, but I can't seem to find it.
I'm hoping that someone on this forum might be able to help me.
Let me now if you require further information in order to help me...

Solved! Go to Solution.

Good news, I finally managed to resolve the problem.
The cause was indeed a bug in the emulation software, I found the solution over here...
Basically I had to turn off Cisco Express Forwarding in order to get inter-vlan routing to work.
After issuing the no ip cef command on my Layer 3 Switches everything worked like it was supposed to.
A big thank you to Mohammed and Georg Pauwen for helping me along the way...

Hi!
I think MAYBE you have problem with the routes- (both static and dynamic), you implemented static on NYDist1-3 that means everything routes to NYCore1 or NYCore2. Can you run "show ip route" on NYDist1, NYDist2 and NYDist3 and post it? I don´t understand why you don´t have any subnet under "router ospf 1" on NYDist3.

Hi Mohammed,
You are correct to state that I shouldn"t have implemented static default routes on my Distribution Switches. (Instead I need to use the default-information originate command on my actual routers) However, while this is indeed a mistake, I don't believe it causes the issue of the inter-vlan routing since there are better matches for the IPs of the hosts in the routing table.
I deleted the static routes just to be sure and turned off all the core and distribution switches except NYDist1.
In theory I should still be able to route between vlans with only the blue devices in the topology above being active. (I'm hoping to pinpoint the problem by minimizing the area of possible failure)
The 2 DEVPCs are in the same VLAN (30/DEVELOPMENT) and are able to ping to eachother, they have an IP of 172.16.30.20 and 172.16.30.21 respectively with a default-gateway of 172.16.30.11 (I also turned glbp off) They are also able to ping their default gateways (172.16.30.11) and the other interface vlans on the NYDist1 switch (like 172.16.70.11 and 172.16.20.11), but I do get the following message when tracing the route (ICMP type:3, code:3, Destination port unreachable). Which I found strange, since I'm able to ping without any issues. I'm still unable to ping the FINPC (172.16.70.20 in VLAN 70/FINANCIAL) or the SALPC (172.16.20.20 in VLAN20/SALES) from the DEVPCs and vice versa.
Here is the routing table of Dist1:
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP a - application route + - replicated route, % - next hop override Gateway of last resort is not set 172.16.0.0/16 is variably subnetted, 30 subnets, 4 masks C 172.16.1.8/30 is directly connected, Port-channel1 L 172.16.1.10/32 is directly connected, Port-channel1 C 172.16.1.36/30 is directly connected, Port-channel2 L 172.16.1.38/32 is directly connected, Port-channel2 C 172.16.1.40/29 is directly connected, Vlan1 L 172.16.1.41/32 is directly connected, Vlan1 C 172.16.10.0/24 is directly connected, Vlan10 L 172.16.10.11/32 is directly connected, Vlan10 C 172.16.20.0/24 is directly connected, Vlan20 L 172.16.20.11/32 is directly connected, Vlan20 C 172.16.30.0/24 is directly connected, Vlan30 L 172.16.30.11/32 is directly connected, Vlan30 C 172.16.40.0/24 is directly connected, Vlan40 L 172.16.40.11/32 is directly connected, Vlan40 C 172.16.50.0/24 is directly connected, Vlan50 L 172.16.50.11/32 is directly connected, Vlan50 C 172.16.60.0/24 is directly connected, Vlan60 L 172.16.60.11/32 is directly connected, Vlan60 C 172.16.70.0/24 is directly connected, Vlan70 L 172.16.70.11/32 is directly connected, Vlan70 C 172.16.80.0/24 is directly connected, Vlan80 L 172.16.80.11/32 is directly connected, Vlan80 C 172.16.90.0/24 is directly connected, Vlan90 L 172.16.90.11/32 is directly connected, Vlan90 C 172.16.99.0/24 is directly connected, Vlan99 L 172.16.99.11/32 is directly connected, Vlan99 C 172.16.100.0/24 is directly connected, Vlan100 L 172.16.100.11/32 is directly connected, Vlan100 C 172.16.110.0/24 is directly connected, Vlan110 L 172.16.110.11/32 is directly connected, Vlan110

Hello,
judging from the configs you posted, the inter-Vlan routing occurs on NYR1 and NYR2 ? Can you post the configuration of those two routers ?
05-12-2018 12:02 AM - edited 05-12-2018 12:10 AM
Thanks for your reply,
I'm afraid the routers haven't been configured yet. The inter-vlan routing is supposed to take place on the Layer 3 switches (using SVIs). I wanted to get the internal VLAN connectivity working before worrying about Network Address Translation and external communication to the ISPs on the routers.
All the ports on the Core-switches are routed ports, and the ports in link-aggregation on the Distribution switches are routed ports as well, while the ports going to the access switches are all switchports in trunking mode.
I also added some more information about my problem in my reply to Mohammed, so if you're able to, you might want to read that reply as well.
Thanks in advance,

Hello,
I don't seem to see 'ip routing' enabled on any of the switches (or maybe I am overlooking something) ?
05-12-2018 04:44 AM
That's because show run doesn't show all the default configuration commands. When I issue show run all the ip routing command does appear in the running config. My routing table also isn't empty, so there's that.
05-12-2018 04:54 AM
Hello,
something fundamental must be missing. What does your VTP look like, do you have a domain configured ?
Post the output of 'show ip route' from one of the distribution switches...
05-12-2018 05:23 AM
Hi!
If you want to see routing tabell on one of the NYDist, he or she posted before: see the previous post. Can post show ip arp on VLAN 20 and 70?
Can you shutdown the Links from NYSw5 to NYDist4, because of you are not configurated routing yet. When you shutdown those links i think you will see a diffrence. Please post show ip arp those vlans you do have a problem before you shutdown those links and arter!
How do you created vlans? I don't see any VLAN id and Names om the configuration you send yesterday

The problem might be with the GLBP...what is the output of 'show glbp 30' ?

Here is the output when only NYDist1 is turned on (I temporarily turned off the other Layer 3 switches to isolate the problem. Inter-vlan routing should be possible with just this one Layer 3 switch since both access switches have a link to Dist1)

I have already turned off all layer 3 switches except NYDist1, I do use VTP to propagate my VLANS, NYDist1 is the VTP-server of domain NYVTP (password is also NYVTP [Since this is just a simulation, I don't mind to share it, I probably change it later anyway]).

Hi!
As long every thing looks like fine:) But something has to bee wrong, i could not see any thing yet, but please post those show commands, to figure out if there is any arps on PC on the difference vlans:
Can you post "show ip arp those vlans" you have a problem?
Can you post show spanning tree on those interfaces between Dist and Switchs?
Do you know which switch is root for spanning tree?

Here you go,
NYDist1: show ip arp vlan 30 and 70

On my access switches (Layer 2) I only have a vlan interface with an ip for my MANAGEMENT vlan 99, so I can't use the show ip arp vlan 30 or show ip arp vlan 70 command
NYASW1: show ip arp

Hello,
I just labbed this in GNS3, I agree with Mohammed, the configs look fine. Which switches are you using ? And which hosts/PCs ?
