Best LAN Network Architecture

[Rowlands Price]

Dear Support,

I have Two sites (SITE A and SITE B).

SITE A: a 3750-12s distribution switch with a vtp domaine called SITE_A with some vlans

SITE B another 3750-12s Distribution switch with a vtp domaine called SITE_B with also somes vlans

The two sites were connected by a micro wave link of 20 Mb/s

Recenty, we connected the both sites by a straight fiber optic (see the diagram attached), the fiber is connected on each distribution switch on à gigaethernet port.

To keep the existing routing between the two sites, we configured the fiber optic ports as routed with a ip address.

so my question is; Can change the design an configure the both site on the same VTP domain?

the both distribution swicth will be the vtp server in the same vtp domain

The distance between the sites is around  0.63 miles

What is the best design for my case?

Need your precious help

If you use a routed port, you won't be able to carry VLAN 5.

Again, you use a trunk port, and configure that trunk port to only carry VLAN 5 and a new VLAN that's only used to build a p2p transit VLAN.  The latter logically takes the place of the routed ports.

Many thanks Joseph

i will create a trunk instead of routed ports (see new diagramm), create a new vlan 2 on both switch, site A vlan 2 ip 10.168.0.1/30 and site B vlan 2 ip 10.168.0.2/30

will do the static routing on site A to reach all ip ranges on site B next-hop 10.168.0.2

From site B, to reach also internet, 0.0.0.0/0 next-hop 10.168.0.1

and on the trunk allow vlan 5 and vlan 2

This is right?

Yes, that's correct.

BTW, you can still extend VTP between site if the VTP domain names match.  Be careful about that.  Although static routing works, you might consider using dynamic routing.  IPBase supports RIP.

Many Thanks

Going to office and test it

but the VTP domain names are different from both site, is it a problem?

SITE A: vtp domain is SITE_A

SITE B: vtp domaine is SITE_B

Should not be (a problem).

Hi Joseph

Many many Thanks

Just done the new config and it's working very fine

The transit vlan working fine and vlan 5 is crossing the trunk

Best Regards

[Rowlands Price]

Hi Joseph

The solution is working fine, many thanks, 

Another question, i want to enable the qos on the trunk link

I want to allow 50 percent of bandwith to vlan 5 crossing the link, how can i do it on the both switch?

Regards

You would enable QoS globally, then map all VLAN 5 traffic to one queue on the transit ports, setting those ports' VLAN 5 queue to 50%.

[Rowlands Price]

Hi Joseph,

Global qos is enable on the switch, can you please remind me the command for mapping all traffic vlan 5 to a queue on ports?

[Rowlands Price]

Hi Joseph

Thanks for you response.

My concern is about one particular vlan,

with routing, is it possible to have a vlan 5 on site A and have the same vlan on site B too in the same ip range? This is why i want to use L2 link to carry all vlan between the both sites.

I have servers in site A and want to have others servers int site B with the same ip range, how can i do this?
