Route specific traffic out backup ISP?

L4 Transporter

We have dual ISP (ISP-A and ISP-B) and utilizting PBR which works just fine.  Now I have use case whereas I have a NAT configured on ISP-B (1 to 1) and I want to force traffic to a specific destination out the backup interface.  I want to do this to ensure traffic destined for a specific address IP-B is sent out the backup interface.  I tried adding a specific route on the VR with the interface and next hop as ISP-B but the path from behind the PAN still takes the primary interface and hop.  

 

I am missing something but not sure what?

@drewdown,

It'll kill traffic depending on what the identified application is; however if you kept sending the traffic it would continue to use the established session which is what you were running into. Going forward if you want to verify that the traffic isn't running on an old session use the 'clear session all filter' command from the CLI and you can specify everything you did with the test command to ensure all traffic will be utilizing the new policies. 

Thanks..

 

BTW I don't see anything your first post regarding PBR, its like you attached or pasted a pic but I dont see anything.  

@drewdown,

I didn't include a configuration example for PBF in my first post, however if you need one just let me know ... also stop calling it PBR. Its Policy Based Forwarding now bud, you leave those Cisco/Juniper terms where you found 'em ;-) 

@BPry Old habits die hard I guess.  And PA could have just as easily called it PBR.  :)
