Inter vlan routing

bobson143
Level 1
Level 1

Im trying to have inter vlan routing using layer 3 switch but failed. Below is the routing table of layer 3 switch. Any help is highly appreciated.

 

Gateway of last resort is 192.168.0.251 to network 0.0.0.0

C 192.168.120.0/24 is directly connected, Vlan120
C 192.168.210.0/24 is directly connected, Vlan210
C 192.168.150.0/24 is directly connected, Vlan150
C 192.168.180.0/24 is directly connected, Vlan180
C 192.168.110.0/24 is directly connected, Vlan110
C 192.168.130.0/24 is directly connected, Vlan130
C 192.168.160.0/24 is directly connected, Vlan160
C 192.168.200.0/24 is directly connected, Vlan200
C 192.168.140.0/24 is directly connected, Vlan140
C 192.168.250.0/24 is directly connected, Vlan250
C 192.168.190.0/24 is directly connected, Vlan190
C 192.168.170.0/24 is directly connected, Vlan170
C 192.168.0.0/24 is directly connected, Vlan10
C 192.168.50.0/24 is directly connected, Vlan50
C 192.168.1.0/24 is directly connected, Vlan1
C 192.168.100.0/24 is directly connected, Vlan100
S* 0.0.0.0/0 [1/0] via 192.168.0.251

Hello

 You need to run the command "ip routing"

conf t

 ip routing 

Yes IP routing is enabled.

need more info like topology setup, PCs IPs that fail. this table does not tell us why it failed? and what has failed?  are PCs directly connected to that switch and have correct default gateways set (pointing to interface vlan x)?  Are PCs on correct vlans and in access vlan xyz ?

The scenario is we have 1 core switch L3 and 2 L2 switch. Switch IP is under Vlan 10 (IP L3=192.168.0.10, L2=192.168.0.11, L2=192.168.0.12) All pc connected to layer 2 switch, with each switch have an uplink going to L3 switch. In each PC I can ping Vlan IP interface regardless what Vlan is the PC. But Once I ping PC IP address in other VLAN it reply Request timed out. All Vlan can ping PC under Vlan 10. PC under VLAN 10 cannot ping PC on different VLAN.

Thanks for posting the running config. Would you post the output of the command show ip interface brief? Also please post the output of the command show arp (or show ip arp depending on the version of code).

I notice that interface vlan 200 has access list INTER_VLAN applied but I do not see that access list in the config. Depending on the version of code running the result could be that all traffic is denied (if older code) or that all traffic is permitted (newer code). I suggest that either you configure the access list or that you remove it from the interface.

Here is what I see so far: I do not see any particular issues about routing in the config. ip routing is enabled, the vlan interfaces are up/up, the vlan subnets appear in the routing table. But I do see some indications of problems, particularly in looking at the arp table I see a number of "incomplete" entries for addresses in vlan 1 and 10. All other subnets appear to have no issue but these 2 subnets (192.168.0.0/24 and 192.168.1.0/24) some hosts are reachable and some are not.

In looking at the config I notice that most of the vlans get their IP addressing from DHCP configured on the layer 3 switch. But the 2 vlans where there are issues do not get their addresses from DHCP on the layer 3 switch. Where do the hosts in these vlans get their IP address? 

In reading the original post again I focused on this statement " PC under VLAN 10 cannot ping PC on different VLAN" and I suspect that some of the PC in those vlans do not have correct gateway information (and/or perhaps incorrect mask for the IP address).

Hello Rick thank you for your patience helping me, just want you to know that the switch configuration was done by previous staff which no longer connected to the company I am working right now. What advice can you give? I am planning to reset the switch to factory settings to reconfigure it. Because right now I cannot setup my Domain directory. My plan is to have a windows DHCP server. For the meantime since I have problem with intervlan routing what I've done is to make the L3 switch as DHCP server base on the Vlan setup created in the existing switches.   

You are welcome. If someone else configured this switch you are certainly able to start over and configure it. But I am not sure what you would do differently. Other than the access-group on vlan 200 I am not seeing things in the config that look like problems.

Up to this point we have been looking at issues about some PCs not being able to ping some devices. Based on what we know so far it is my opinion that this issue is something external to this switch. So I am not confident that a new/fresh configuration of the switch will fix this issue. Now you describe a different aspect about setting up your Domain directory. I am not clear what is involved/not working. But I would suggest that it might be better/easier to fix that issue in the current config rather than start over with a fresh config.

Hi Rick,

Is it possible that the firewall is responsible of blocking the inter vlan-routing? see below IP route, 192.168.0.251 is the IP of the firewall.

Gateway of last resort is 192.168.0.251 to network 0.0.0.0

C 192.168.120.0/24 is directly connected, Vlan120
C 192.168.210.0/24 is directly connected, Vlan210
C 192.168.150.0/24 is directly connected, Vlan150
C 192.168.180.0/24 is directly connected, Vlan180
C 192.168.110.0/24 is directly connected, Vlan110
C 192.168.130.0/24 is directly connected, Vlan130
C 192.168.160.0/24 is directly connected, Vlan160
C 192.168.200.0/24 is directly connected, Vlan200
C 192.168.140.0/24 is directly connected, Vlan140
C 192.168.250.0/24 is directly connected, Vlan250
C 192.168.190.0/24 is directly connected, Vlan190
C 192.168.170.0/24 is directly connected, Vlan170
C 192.168.0.0/24 is directly connected, Vlan10
C 192.168.50.0/24 is directly connected, Vlan50
C 192.168.1.0/24 is directly connected, Vlan1
C 192.168.100.0/24 is directly connected, Vlan100
S* 0.0.0.0/0 [1/0] via 192.168.0.251 

For now I will not reset the switch, I will try to fix the issue as you said it is external and not on the L3 switch. I will check other devices connected to switch specially the firewall.

 

It is highly unlikely that the firewall is affecting inter vlan traffic. Packets to an outside/remote network would go through the firewall and could be affected. But packets from a device in one local vlan/subnet to a device in another local vlan/subnet should flow directly and I do not see how the firewall could be involved.

In a prior post I suggested that you use these steps in investigating the issue. On a PC that is having problems try these steps

- check its IP address, mask, and default gateway. are they what you expect?

- can it ping its default gateway?

- can it ping the vlan interface IP of other vlans?

- what does traceroute (or tracert) to an IP in another connected subnet do?

- what does traceroute (or tracert) to an Internet IP do?

Hi why always the first hope is the FW ?
I see your DHCP config the default router is VLAN not FW.
can you check see what is GW for all host
