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,

Yep, I was 99% sure that was the case.
The Asus router supports OSPF just fine. OSPF v2 and v3 is supported. v3 if I ever want to tinker around with IPv6, but not now.
So I've enabled OSPF on the Asus router. And both the Cisco and Asus exchanged the databases successfully. Now inter-VLAN communication was not broken but access to the web / internet was broken for all VLAN's. I figured this out as well. A bunch of NAT rules were removed when the router was reconfigured from Gateway to OSPF Router. I'm about to add them back in to see if web access will work even if OSPF is enabled on the Asus router.
This brings me back to my original question. When reading in the DD-WRT help menus, it had the following comment:
Note:
Dynamic Routing is not available in Gateway mode.
Hence why I asked.
Thx,
TK

As you've indicated in an earlier post, I've enabled OSPF v2 on the Asus DD-WRT router, changing it from a Gateway router. This took a bit of tweaking since I had to add some NAT rules to make this work. Again, something you also indicated. A twist was that the earlier Asus DD-WRT firmware either didn't support NAT w/ OSPF or had a bug. I had to update the Asus DD-WRT firmware to DD-WRT v3.0-r40559 std (08/06/19) to fix that.
Wrote it up and shared it here: Asus, Cisco 3750G, OSPF v2 and intervlan routing.
So followed everything nearly 100% exactly as you've specified above w/ the exception of the firmware issue, and everything works as expected wo/ static routes on the Asus router. Thank you very much again! Very much appreciate both your help here gentlemen.
Thx,

Spoke too soon. After removing the static routes, ping still worked but I didn't give it enough time. Sometime overnight ping stopped to work for VLAN 2, 3, 4. I added the static routes back and OSPF picked them up again.

Looks like I have to keep the static routes unless I'm missing something in the OSPF configuration. I guess what I'm not really clear on is how OSPF picks up routes if I don't have any specific ones defined? The only way I can see how is from the packet itself if not from anything statically defined.
I've included the software versions above in case there's a version mismatch between OSPF implementations or F/W versions?

Hello
As you have continually changed you ip addressing its hard to keep track as to what you now have applied to the switchs and router, anyway looking at you most recent posts ospf adjacency haven't established so hence you dont have connectivity when you remove your static routes.

So first of all make sure you have the correct ip addressing relating to the ospf config you've applied.
As for the adjacency, you need to make sure the ospf network types on both devices are the same.
sh ip ospf interface xx
As this is a switch connecting to a router you may have mtu mismatch between there interfaces which can be negated by applying the following:
int vlan 1
ip ospf mtu-ignore
Lastly run a debug to as to why the ospf adjacency isn't establishing
debug ip ospf adj

Ah, yes, right. Since I thought everything was working now, I've added a third router to get my entire network on OSPF. The original is still correct and hasn't changed but there is another router in the setup. My topology is now as follows:
VLAN 1: 192.168.0.X / 24
VLAN 2: 10.0.0.X / 24
VLAN 3: 10.1.0.X / 24
VLAN 4: 10.2.0.X / 24
Asus Router: 192.168.0.6
Cisco 3750G: 192.168.0.1 w/ 192.168.0.2 as secondary.
Asus Router 2: 192.168.0.7
Server 1: 192.168.0.123 ( VLAN 1 )
Server 2: 10.0.0.72 ( VLAN 2 )
Server 3: 10.0.0.73 ( VLAN 2 )
KVM Virtual 1: 192.168.0.101 ( VLAN 1 - KVM Virtual Machine. Actually curious why it even appears. For the purpose of this scenario, you can think of it as residing on physical Server 1 above. )
So the original is still as-it-was before, minus the additional router.

@Tom Hello,
could you change the configurations below?
From
10.0.0.1 0.0.0.0 area 0 10.1.0.1 0.0.0.0 area 0 10.2.0.1 0.0.0.0 area 0 10.3.0.1 0.0.0.0 area 0 192.168.0.1 0.0.0.0 area 0
To
10.0.0.0 0.0.0.255 area 0 10.1.0.0 0.0.0.255 area 0 10.2.0.0 0.0.0.255 area 0 10.3.0.0 0.0.0.255 area 0 192.168.0.0 0.0.0.255 area 0
And post here the result from
show ip protocols
show ip ospf neighbor
show ip ospf int bri

Reading what this tag means on the Asus side:
redistribute static
Appears like it might be redistributing only single static routes?
12-08-2019 12:15 PM
ok ok.. now i understood what happens... try it.
interface vlan 2
ip ospf 1 area 0
interface vlan 3
ip ospf 1 area 0
interface vlan 4
ip ospf 1 area 0
interface vlan 5
ip ospf 1 area 0
and remove "networks" command under ospf, after it, reset ospf proccess using " clear ip ospf process"
