Hi Everyone !
We have some D-Link equipment @ the office, I was in charged to set a redundant network with several VLans on our equipment. The missing HW will be purchased if necessary.  Here is what we got and what I need to do (not sure how, need some recommendation from some one who is familiar with the equipment and its capabilities !!! )

Actual HW is:

2 x DGS-1224T
2 x DGS-1248T (for now it's only one, but next week we are getting the 2nd one)
1 x RV016 (Linksys VPN Router)
1 D-Link DSL Modem (dsl-524, 1 independent ips connection)
4 motorola cable modems (4 independent ips connections)
1 Mickey Mouse equipment with incoming 10Mbps Fiber connection / several 1GB RJ45 outgoing ports (not sure about the brand, 1 independent ips connection)

What we need to do is:
Fully redundant network on several VLans (4 VLans for a start). Not sure if I'll need 2 different Routers (with multiple WAN connection support) for this to comply with the requested task. The idea is to have 2 Switches for the end user usage and 2 switches for maintenance processes and back up in case of failure of the production switches. Configured with 4 Vlans each one with double path from from the router "1" for performance and one path from router 1 from router "2" for fail over purpose. Also on the Router end the idea is to connect 2 or more WANs (from IPSs) and I am not sure if I can simulate a router feature with some of the  switches by connecting my WANs directly. But the idea is to avoid every possible brake point. 1 modem fails, the 2nd one must continue the productivity, 1 router / switch fails (2 or more WANs are automaticaly lost) the 2nd router / switch must continue providing the connection to the Switch where the end users are connected (for all the VLans on the same device)

Any idea on how is gonna be the best way to implement these products

Thanks to anyone who is whiling to assist in advance,
Maxim

I think you are going to find this task grows in front of your eyes at an unbelievable rate.


I would contact our Sales team at 1 800 326 1688 ext. 5434, they can get you on the right path with finding the products and technologies that will be capable of doing what you need.

OK, I don't really find it that complicated. I am just not familiar with D-Link HW. I will try to explain it in a simple way.

I need to know if the switch is able to work as a router at virtual level. (to connect 2 or more WANs on it), if so, I would like to know if it will be able to manage the load balance of the WAN connections for the same VLAN. (in other words, multiple WAN connection for the same VLAN). If this will work I believe I can handle the installation with the equipment I already have. Also if this works the way explained previously, I would like to know if each VLAN will need a dedicated WAN port configured on the switch or I can use the same WAN ports for every VLAN I have on the switch, if so, what part of tech-documentation do i need to review for this kind of configuration ?

Regards,

The easy answer is that the equipment you have won't do what you need.

I don't want to be a bother but I strongly believe that you are either not explaining your needs perfectly, or grossly misunderstanding the scale of your exact request.

Thank You Fatman ,
You were right about the equipment, after a research I realized that the original idea requires switches with stacking features and routers with vrrp features what unfortunately we don't have at the office.

But also reading on this forum i came up with a simple redundant solution that will work for business needs.
May be you can correctme in case if I got any mistake at the configuration i am planning to use.

1 x 1224t switch trunked with 1 x 1248t switch, both connected to RV016 (linksys) router with double paths.

On 1224t switch:
VLAN (default) 24 ports untagged
VLAN02 1-18 untagged, 19,22,23,24 tagged
VLAN03 20,22,23,24 tagged
VLAN04 21,22,23,24 tagged
PVID 1 on ports 1,22,23,24
PVID 2 on ports 2-19
PVID 3 on port 20
PVID 4 on port 21
Trunking ports are 22,23,24

On 1248t switch:
VLAN (default) 48 ports untagged
VLAN02 43,46,47,48 tagged
VLAN03 1-20 untagged, 44,46,47,48 tagged
VLAN04 21-42 untagged, 45,46,47,48 tagged
PVID 1 on ports 1,46,47,48
PVID 2 on port 43
PVID 3 on ports 2-20,44
PVID 4 on ports 21-42,45
Trunking ports are 46,47,48

On router:
vlan02 on port 1,4
vlan03 on port 2,5
vlan04 on port 3,6
port 1,2,3 to 1224t switch ports 19,20,21
port 4,5,6 to 1248t switch ports 43,44,45

Basicaly, this should work like all vlans on a 1224t switch trunked with 3 paths from 1224t ports 22,23,24 to 1248t ports 46,47,48. with separate pvids for every vlan on both switches with the port #1 shared on both switches as  well. with one path per switch from the router for every vlan. Router will manage each peer of paths as a separate id (ip or vlan id).

Do you think is this configuration will work as planned ?
 
Un-endable Thanks in advance to anyone who may take some time to read this puzzle and even more thanks to whom is able to assist me on this configuration :-)

One more question in case if the theory is correct, can I save 2 ports on each switch by letting  only one on each of them as PVID1 (tagged on all VLANs on both switches) , this will be the port where I will connect the router path on each of the switches. The ports i am referring to are 20,21,22 on 1224t switch and 43,44,45 on 1248t switch?

Thanks for any possible assistance.

If that router has a switched interface instead of independent Ethernet interfaces then I would be reeeaaal careful about potential network loops.  I know nothing of that rouer and it's capabilities though.

I would want to double check your tag/untagged relationships as it is not perfectly clear exactly what your network would require, but I don't see any immediate reason this can't be done.

Thanks Fatman,
I made a picture to make the topology and port distribution more understandable. Please find it below:

[crtech]

Basically my questions are:

1 - When Trunking the switches I am not finding the TAGGing part where on the 48 port switch i place ports 23,24 from the 24 port switches, same backwords, in the 24 port switches the part where i TAGG the ports 45-48 from the 48 port switch. Not sure if these switches work the same way the others do...
  - Is this part is automated by just leaving the Trunk ports TAGGED on all of my VLANs on all the Switches and the trunk will share all the VLans, or am i missing something ?

2 - Should I leave STP feature enabled for all the ports or only for the TRUNK ports and the ports where will I connect my Router on all the switches?

3 - My router supports VLans, I am trying to create redunduncy between "Router & Switches" by making double paths, VLan1 from router to SW1 and VLan1 from router to SW2 paths are under the same ip, and both active from my router end.
  - Will that work like a double bandwidth and redundancy in case of failure?
  - Will that work like redundancy only ?
  - Or that will not work and will cause loop?

4 - Do I need to use PVID feature for this configuration, if so, what is the best implementation of it?

I think once I have this solve I am green to go with my network setup.

Thanks in advance !
