Hi All,
Please bear with me as I'm new to this and relatively new to Networking at this level.
I'm trying to set up inter VLAN routing. Following this post:
I've configured everything I could (or perhaps almost everything except for 6) Configure the interface to the default router. part. ). This is an older Cisco 3750G switch:
VLAN1 192.168.0 (IP 192.168.0.3, Secondary 192.168.0.4)
VLAN2 10.0.0.0 ( IP 10.0.0.1 )
VLAN3 10.1.0.0 ( IP 10.1.0.1 )
VLAN4 10.2.0.0 ( IP 10.2.0.1 )
Now from the switch itself, I can ping all IP's without any issues. For example, I can ping 192.168.0.100 from the switch but not from within VLAN 2 devices. However, I can ping 192.168.0.3 and 192.168.0.4 (secondary), the switch VLAN 1 IP's from within devices on VLAN 2.
Devices on VLAN2 can ping each other, the VLAN IP and even the default VLAN (Switch IP) 192.168.0.3 and 192.168.0.4 above. But nothing beyond the two VLAN 1 IP's above. What am I missing? My first thought is missing trunking or a setting on VLAN1 but I'm not 100% on that nor what those commands would be.
Thx,

Hello
So I guess you are saying static or ospf routing internet access is applicable for only vlan 1?
I assume the Asus is aware of your Lans subnets - be it via static routes pointing back towards your cisco switch or them being learnt via opsf from the cisco switch?
If so that leaves Network Translation ( NAT) on the Asus.
Chain POSTROUTING (policy ACCEPT) target prot opt source destination SNAT 0 -- 0.0.0.0/0 0.0.0.0/0 to:192.168.0.6 SNAT 0 -- 192.168.0.0/24 0.0.0.0/0 to:123.123.123.321 SNAT 0 -- 192.168.45.0/24 0.0.0.0/0 to:123.123.123.321 SNAT 0 -- 192.168.75.0/24 0.0.0.0/0 to:123.123.123.321 MASQUERADE 0 -- 0.0.0.0/0 0.0.0.0/0 mark match 0x80000000/0x80000000 MASQUERADE 0 -- 10.1.1.0/24 0.0.0.0/0
I dont see any translation for those other subnets in this output so does your Asus nat configuration need to be updated to accomodate these other vlans - Have you done this?

Hello
You have duplicate addressing in your ospf config and missing statements also!
And why do you have the same subnets on both devices, surely the cisco is the device for the intervlan routing so you dont need those same interfaces/subnet on the router?
Only ospf statements on the asus which relates to its connect interface towards the cisco is required( whatever that may be) and obviously any wan interface/subnets - what ever they maybe

Hello
What I mean is -
In your routers configurations you show them advertising the Cisco switches subnets - You don’t need to do that.
In a basic ospf setup between devices you would enable ospf only on the interfaces that require opsf adjacency on them and then disable any other interfaces you don’t won’t ospf to run on, then you just advertised those other interfaces in ospf.
Example:
RTRx
Int xx
ip address 1.1.1.1 255 255.255.0
int yy
ip address 2,2,2,2 255.255.255.0
router ospf x
passive interface-default
no passive interface xx
network 1.1.1.1 0.0.0.0 area 0
network 2.2.2.2 0.0.0.0 area 0
As you see only int xx will be running ospf and int yy subnet will just be advertised
Any other subnet/addressing relating to another routers interface then you don’t advertise them.

"But nothing beyond the two VLAN 1 IP's above" <<--- as per the document you have router, Do you routing enabled on cisco Switch and pointed defaut route to router side, and router should have also route back to your network point to switch IP adddess
Example Switch side :
Configure the default route for the switch.
Switch(config)#ip route 0.0.0.0 0.0.0.0 x.x.x
EDIT :
i have missed your routing output somehow how.
S* 0.0.0.0/0 [1/0] via 192.168.0.1
You mean from your IP range not reaching beyond Router you mean? to the internet ?
Can you post switch and router config ?

You didn't miss. I was editing the post with further information. I should have replied below with the extra details instead of keeping it together in the original post.
From the switch itself, I can ping outside to places such as 8.8.8.8. But not from VLAN 2 for example.
Please see below.

There is a second switch sitting at 192.168.0.1 which is a basic Asus GigE / Wireless device. However, I don't see that it would cause any issues here since the issue appears isolated to the Cisco 3750G side.

192.168.0.1 which is a basic Asus GigE / Wireless device - this means from switch or IP from 192.168.0.X working but other VLAN not working for internet, is this correct? in this case, you do not have NAT policies for that IP, please follow below guide to setup.

Yes, this is just a simple two-switch network:
Users / Lab Servers -- Switch 3750 (VLAN 1, 2, 3, 4 exist on this switch ) ( G/1/0/24 ) --Asus -- Internet
Looking from the perspective of the issue, it's even simpler. Servers with IP's on different VLAN's connected to each other VIA the Cisco 3750G are not communicating. So the issue exists even with the Asus router out of the picture. So for example, Server 3 with IP 192.168.0.100 ( VLAN 1 ) can't be reached from servers on VLAN 2.

On this Asus rtr do you have static routes back towards the core switch for those lan subnets
ip route 10.0.0.0 255.255.255.0 192.168.0.3
ip route 10.1.0.0 255.255.255.0 192.168.0.3
ip route 10.2.0.0 255.255.255.0 192.168.0.3
Lastly you will also need NAT statements on this Asus rtr that relate to the lan subnets so to allow internet access for them?
12-04-2019 07:40 PM
@paul driver thank you, however, I already solved the original problem in this post simply by changing the IP of the Asus router alongside changing the IP of the Cisco 3750G router.

Experimented further to get some more information. I took one of the VLAN 2 devices and stuck it on VLAN 3. Now I tried to ping and ssh between the two devices. Both worked. Just doesn't work with default VLAN 1 . Thinking this has to do with this step:
6. Configure the interface to the default router. In this scenario you have a Layer 3 FastEthernet port.
Switch(config)#interface FastEthernet 0/1 Switch(config-if)#no switchport Switch(config-if)#ip address 200.1.1.1 255.255.255.0 Switch(config-if)#no shutdown
However, when I try this (g1/0/24 - Port connected to my Asus Router ), I get this:
mdscisco01# mdscisco01#conf t Enter configuration commands, one per line. End with CNTL/Z. mdscisco01(config)#int g1/0/24 mdscisco01(config-if)#no switchport mdscisco01(config-if)#ip address 192.168.0.6 255.255.255.0 192.168.0.0 overlaps with Vlan1 mdscisco01(config-if)#no shut mdscisco01(config-if)#
12-02-2019 05:06 PM
Hi @Tom
Between your switch and your Asus router you must assign a different network to those already assigned.
For example:
10.3.0.0/30
mdscisco01(config)#int g1/0/24
mdscisco01(config-if)#no switchport mdscisco01(config-if)#ip address 10.3.0.1 255.255.255.252
IP ASUS : 10.3.0.2 255.255.255.252
Try assigning a port on your switch to vlan 1:
interface GigabitEthernet1/0/9 switchport access vlan 1 switchport mode access

Could you please elaborate a bit from a technical standpoint as to why does the Asus router and the port it's connected to on the Cisco 3750G have to be on a different subnet?
The Asus router is the gateway for most of the equipment online so this would be an undertaking. I'd have to move the gateway IP 192.168.0.1 to the Cisco 3750G and re-IP my Asus router. Till now, the Cisco 3750G was simply an extension of the existing network.
Tried forcing the VLAN 1 on a single port, but that didn't work either.

I did do some more investigating and found that when I attempt to ping Server1 192.168.0.101 (VLAN 1) for example, from Server2 10.1.0.73 (VLAN 3) the request does get to Server1. Server1 replies but it goes nowhere:
Server1
00:22:42.847287 IP 10.1.0.73 > 192.168.0.101: ICMP echo request, id 17409, seq 6, length 64 00:22:42.847310 IP 192.168.0.101 > 10.1.0.73: ICMP echo reply, id 17409, seq 6, length 64
So I would surmise that since the Asus router is set to Gateway mode, it doesn't really forward the reply anywhere? So I checked and see that the Asus did capture the request and reply fine:
Asus

And then is apparently sending it back to 10.1.0.73. But I'm not sure through where yet. I can't get a monitor configured on the switch successfully yet. Tomorrow.

Odd. Left ping running from VLAN 1 machine ( 192.168.0.101 ) to a VLAN 3 machine ( 10.1.0.73 ) overnight. This morning I check and the ping command returns a successful ping reply:

Yet can't ping 10.1.0.1 from said VLAN 1 machine. I did reload the Cisco 3750G switch before doing so.
Before I go ahead and re-IP my Asus switch, any other settings I can check or adjust?
