Vlan Configuration CISCO 3560

[health.net]

Hi,

A brief explanation will give you an idea, before answering my questions...

I have 2 locations, at a distance of 600KM.

These two locations are well connected by Point to Point L2 VLAN with a speed of 2 MBPS and supported by CISCO 3560G switches.

Location A has a VLAN to communicate to the other VLAN at Location B.

Location B has also got 3 VLANS which are inter connected with Location A.

Now the hardware in one of VLANs in Location B has moved to Location A for obvious reasons.

For further refernce am giving the VLAN IP address here....

Location A

VLAN1 for communicatng to Location B

IP Range                172.20.44.210

Subnet Mask          255.255.255.0

Default Gateway     172.20.44.210

VLAN2 for the desktops in Location A

IP Range                192.193.194.1-255

Subnet Mask          255.255.255.0

Default Gateway     192.193.194.1

Location B

VLAN1 for receiving traffic from Location A

IP Range                172.20.44.209

Subnet Mask          255.255.255.0

Default Gateway     172.20.44.209

VLAN2 for the desktops in Location B

IP Range                10.55.60.1-128

Subnet Mask          255.255.255.128

Default Gateway     10.55.60.129

VLAN3 for the server in Location B

IP Range                10.55.61.1-128

Subnet Mask          255.255.255.128

Default Gateway     10.55.61.1

VLAN4 for the other equipment in Location B

IP Range                10.55.60.129-255

Subnet Mask          255.255.255.192

Default Gateway     10.55.60.129

Now my questions are as follows.....

1.How do I share the internet in Location A to Location B.

2.How do I have all the VLANs in the same network (ip addresses), to avoid confusion.

For Example...

IP Address Range           10.44.71.1-255

Subnet mask                  what ever applicable

Default Gateway               10.44.71.150

Hope am clear in asking the question.

Thanks in Advance in resolving my issue.

I think the 3560 switch(Location A) is capable in routing. You will need to put static route(Location A Switch) from vlan X(as a source of you internet) to vlan 1 where the location B connected. Then also static route in Switch in Location B in order for the request to send it back. I hope this will help

If the switches are connected via a layer 2 LAN as you stated and you want to unify the addressing, why not configure a trunk port between the switches, run a common vtp domain, and have one set of Vlans between the sites rather than separate Vlans at each site?

Hi Vijay,

There are different options to make this work. But anyways as per your explaination you have access between LocationA & Location B subnets.

Location A is the internet Hub. Location B is connecting to location A for internet. So location B subnets endpoint default route to be pointed to Location A.I guess default route is already there. You have the trunk interface by having all the VLAN's routed and connection to P2P link. Same way Switch @ Location A is connected to the router which is connected to ISP(Internet). No matter whatever you have you can mention the NAt rules in such a way to access internet.

VLAN1,2,3,4 should get trunked when connecting to Location A. The same should get routed to Internet @ Location A.

If you provide your design we can suggest a best fit solution for the same.

Please do rate if the given information helps.
