configure Policy Based Routing - CISCO Router 2800 - ASA 5510

Unanswered Question
Jun 15th, 2009

Hi All,

Our network is configured as follows:

Cisco Router 2800:

External Interface:

- Two ADSL WAN modules (for internet connectivity)

- A CISCO Switch 2950 on the outside interface which is connected to WIFI APs .

Internal Interface:

- CISCO ASA 5510 which is in turn connected to a CISCO Switch 3560 POE

See attached diagram.

We have created two VLANS within the Switch and distributed our clients accordingly.

We do not have a dedicated IP assigned by our ISP but instead use a Dynamic IP service No-IP.com.

We run the following that require access from external to the network: Exchange email, OWA, SharePoint and VLAN

We have been trying to distribute the traffic to optimise bandwidth utilisation by segregating networks users.

Thank you

I have this problem too.

Subash,

You may try to do load-balancing for outbound direction.

Please check out these links.

In case you really want to do PBR. You can separate source of traffic(f.e. 1 vlan each link/ISP) to do PBR on the router. However the links I provided will save you from NAT problems.

Subash,

Sorry for replying you too late. In case you want to do MLPPP. You have to make sure that 2 ATM interfaces coming from the same ISP/the same router(Properly be). Because you have to configure this requirement on both sides.

HTH,

Toshi
