I have Two Lan Uplink for my network with respective Private IP (Uplink 1: 192.168.2.0/24 and Uplink 2:192.168.94.0/24).
I want to merge both the Lan IP and route it through different IP address 10.10.10.0 (Vlan202).
so that i can access both the services of different Lan.
Note:I cant change Lan Network of the uplink as it is provided by contact center.
Thank you in advance.

Hello @samphu,
Greetings,
Actually to allow these different networks to reach each other, you will need to configure:
1- On the L3 Switch the following:
#ip routing
Also, don't to forget to assign for each device its gateway,
for example for PC0, the gateway will be the IP add of the interface vlan 202.
2- On R1 (the left one):
you will need to configure static routing:
#ip route 192.168.94.0 255.255.255.0 192.168.2.x
#ip route 10.10.10.0 255.255.255.252192.168.2.x
note 192.168.2.x this it the IP address of interface Gi0/1 of the 3560 SW.
3- On R2 (the right on):
you will need to configure static routing:
#ip route 192.168.2.0 255.255.255.0 192.168.94.x
#ip route 10.10.10.0 255.255.255.252192.168.94.x
note 192.168.94.x this it the IP address of interface Gi0/2 of the 3560 SW.
Now, everything is done!
Another option is to use any routing protocol on the 3 devices, like RIP, EIGRP or OSPF!
If you are interested more to use any of these protocols please, confirm!

Can you let me know what model of routers are you using?
Is it Cisco ?
Why you can not preform the static route ?

Hello dear,
Sorry for the late response!
First and according to @Deepak Kumar suggestions (in case that you can not access the routers configuration) regarding the NAT, you should put in consideration that 3750 is not supporting NAT! so it can not be a solution!
Second, I am still thinking the same, you need to have an access to the routers and to configure a static route or to use any routing protocol!
Can you please confirm that you can access the routers to configure it?
If yes, I can help to write for you all the commands needed to finish you task!
Please, don't forget to rate all helpful responses and mark solution!
It will be so nice from you!
Thanks in advance,
Bst Rgds,

Hi,
As I am understanding that your vendor is not adding your local subnet 10.10.10.0/24 on their routers so you are not getting back a reply from the concerned system/router.
If it is correct then I believe that you have only option to go with NATing. Currently, NATing is possible on routers and some selected Nexus switches. So I thought the router is a best and cheaper solution for you.
As you mentioned that you don't have any sort of access to those routers so it is not possible to do anything with a routing protocol.

Hi,
Your Switch configuration will be like:
Enable L3 routing on Catalyst switches
SW#config t
SW(config)#ip routing
SW(config)
!
View routing table
!
SW#show ip route

Hi,
As I am understanding your question you are seeking a guide for accessing all resources which are behind or on networks as 192.168.2.0/24 and 192.168.94.0/24 from your LAN subnet 10.10.10.0/24. If Yes, then
There are two steps for the same:
1. Enable IP routing on your L3 switch with help of "IP routing" commands.
2. Add static route (default if required) toward to a router (as per subnet hosted) IP address.
