Loadbalancing on catalyst 3750

Hi,

We hv a cisco 3750 switch configured with different departmental vlans.

Similarly we hv a vlan configured for WAN routers.

Wan will be setup in the near future.

There will be 2Nos. 1800 routers connecting to different service providers.

Routers will be running BGP.

What we want is to allow loadbalancing of traffic initiated from Lan to Internet.

i.e.

if we hv two subnets configured on cisco 3750 switch, we want one subnet to go to internet via router 1 and the other subnet should go thru router 2.

Clarifications:-

Can this be achecived using feature such as policy based routing.

what all is required on the cisco 3750 ..

can i get a sample config depicting this scenario.

Regards

Re: Loadbalancing on catalyst 3750

Hi,

Policy-based routing is indeed what you need.

A sample config would be as follows:

interface VLAN10

! first local subnet

ip policy route-map ToWAN1

!

interface VLAN20

! second local subnet

ip policy route-map ToWAN2

!

route-map ToWAN1

match ip address 10

set ip next-hop

!

route-map ToWAN2

match ip address 20

set ip next-hop

!

access-list 10 permit

access-list 20 permit

Hope that helps - pls do remember to rate posts that help.
