Terminating Dual Internet Leased Line on Single Router

Unanswered Question

Dear All,We have a central office with 64kb internet leased line.

Internet leased line is used for browsing , email-traffic , to access SAP application through VPN sessions initiated by mobile users.

Problem we are facing is mobile users are complaining about performance issues.

We have ordered second 64KB leased line , can we terminate the second Internet leased line on the same router.

Can we do bandwidth management i.e using one leased line for VPN traffic and other for rest of the traffic

Is it possible , Pls advice with the sample config for the same.


Regards

Deepak.

You can terminate the 2nd line on the same router if the router has the appropriate interface. Different router models can accomodate different numbers of WAN interfaces.


You can send VPN traffic over one link and all other traffic over the other link via Policy Routing, but this only affects outbound traffic. To control inbound traffic you'd have to ask the ISP to route traffic destined to the VPN endpoint(s) down one link and all other traffic down the other link. They may or may not be willing to do so.

The 2nd link should be configured the same way the current link is configured, save for different IP addressing.


As for the routing, take a look at Policy Routing to route traffic based on source address or port number in addition to destination address: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configuration_guide_chapter09186a00800c75d2.html
