Policy based routing using tunnel interface

[john.dejesus]

Hi,

I would like to ask your opinion and suggestion regarding my network lab scenario. Basically I have multiple ISPs attached to a LAYER 2 SWITCH, these are 2 DSLs and 2 E1s premium Internet lines and also I am running OSPF on the network. I have attached the diagram for your reference. My goal is to create a policy to route http and ftp traffic coming from ASW_LAN going to DSL network. I was thinking to create a GRE tunnel between CSW_LAN(3560) and DSL_ROUTER(2611XM), and configure a PBR on CSW_LAN and use the tunnel ip of DSL_ROUTER as my next hop in the route map rule. Any suggestion and opinions are highly appreciated. Thanks in advance.

not sure whar switch model is your as there are some limitations with GRE on some switches

Q. Does the Cisco Catalyst 3750 Series support GRE tunneling?

A. No. The Cisco Catalyst 3750 Series can switch "transient" GRE tunneled traffic in hardware at wire-rate but it cannot act as GRE tunnel end-points.

Q. Does the Cisco Catalyst 3560-E support generic routing encapsulation (GRE) tunneling?

A. No. The Cisco Catalyst 3560-E can switch "transient" GRE tunneled traffic in hardware at wire rate, but it cannot act as a GRE tunnel endpoint. Future support of GRE tunneling in software is possible

unless you have 450 or 6500

th eother option you can put your PBR on the input interface of CSW_PWAN connected to the internal ASA1

and se the next hop as the ADSL router interface
