HI Naidu,


Consider the Locations as HO & BO


HO:

Sicne you have only L2 Switches. Use the IP Address of the Router Interface connecting to the Switch as Gateway address of all Clients in HO


HO - BO:

You can configure the end - to - end communication between these two offices with some Routing Protocols / Floating Static Routes since you use the Redundancy. You can use Ethernet Comm... / Serial Port Comm...based on your Service Provider, Cost, etc.,


BO:

same as HO Setup as per your post.



PLS RATE if HELPS

HI Naidu,


Yes.


INFO:If you are going to have VLAN Setup in your environment then VLAN Router IP will be the Gateway IP Address of the Clients. (Since you have only L2 Switches this may not be required for you neverthless as Tech Info).


For redundancy you can use Floating Static Routes. Primary Static Route as default to Primary link and Secondary (redundancy) static route to Backup Link with AD as 200.


Else, you would like to use only protocols for redundancy then EIGRP, OSPF, etc., Refer link below for study documents:

HI Naidu,


Consider as below for subnet details:

VLAN 1: 10.1.0.0

VLAN 2: 10.2.0.0

VLAN 3: 10.3.0.0


For each VLAN you will have a Router IP.


VLAN 1 Router IP (eg:10.1.0.1)

-->as Gateway for clients in vlan1

VLAN 2 Router IP (eg: 10.2.0.1)

-->as Gateway for clients in vlan2

VLAN 3 Router IP (eg: 10.3.0.1)

-->as Gateway for clients in vlan3


INFO: You don't have to create sub-int in router fa0/0 for each VLAN.


===>Fa Eth 0/0 of Router A in HO can connect to Fa Eth 0/0 of Router B in BO for WAN Connectivity.


Finally, the IP Subnet of entire 10.0.0.0 Subnet Network must be routed over WAN.
