WAN traffic routing

we have 4507 as core switch,3560 as edge switch .Edge switches are connected to core switch using ether channel.Following are the data vlans in the network

Vlan 301 - 192.168.32.0/24

Vlan 302 - 192.168.33.0/24

Vlan 303 - 192.168.34.0/24

Vlan 304 - 192.168.35.0/24

Vlan 305 - 192.168.36.0/24

Vlan 313 - 192.168.44.0/24

Vlan 315 -  192.168.45.0/24

Vlan 316 - 192.168.46.0/24

Vlan 317 - 192.168.47.0/24

Vlan 318 - 192.168.48.0/24

Vlan 319 - 192.168.49.0/24

vlan 320 - 192.168.50.0/24

Vlan 321 - 192.168.51.0/24

Vlan 322 - 192.168.52.0/24

Vlan 323 - 192.168.53.0/24

Vlan 324 - 192.168.54.0/24

vlan 325 - 192.168.55.0/24

our client is planning to take 5 separate PPoE broadband  internet connection for this project.The client want to route traffic from

Vlan 301 to port connecting  first internet connection

vlan 302  to port  connecting  second internet connection

vllan 303 to port   connecting  Third internet connection

vlan 304 to  connecting  Fourth internet connection

and rest of the vlans to fifth internet

I want to know is it possible to route traffic from particular vlan to  specific  ethernet port connecting to internet.if it is possible which router can be used for this solution and how traffic  can be routed.

please advise me

Re: WAN traffic routing

Assuming the SUP on the 4500 is able to do L3 and the NAT are done by seperate devices (Catalyst 4500 and 3500 doesn't support NAT), then you should be able to do PBR.

Re: WAN traffic routing

If we are doing policy based routing ,the internet  connection should be terminated directly to core switch 4507.In this case which device i can use for NAT ing function

Re: WAN traffic routing

This is the problem where the 4507 cannot do NAT. You might want to terminate the internet connection on seperate routers (not switches, the only switch that support NAT is the Catalyst 6500).

Re: WAN traffic routing

Is it possible to terminate all internet connection in a single router connecting to core switch and do PBR and NAT on this router.

Re: WAN traffic routing

Can i use cisco small  business routers.

Depends on the bandwidth of your requirements.

Re: WAN traffic routing

Each broadband internet  connection speed is 32 Mbps.Does smal business routers is efficient to do dynamic  NAT ing

which router should be  used in this situation if i am using separate routers for each internet connection.

Is it possible to do the solution with single route instead of multiple routers.

Re: WAN traffic routing

I doubt if any SB router can do 32 mb EACH.

New Member

Re: WAN traffic routing

It means if i have five 32 mbps PPoE broadband  internet connection ,I need five routers to impliment this solution.

Which  cisco router is prefered for this solution.

Re: WAN traffic routing

Does anyone has solution to this scenario

Re: WAN traffic routing

I'd be looking at a 1841 router.  The router is rated at 75Mbps (half-duplex, un-encrypted).

Hi Leo,

The OP needs to terminate 5 PPPoE in one router.
