PBR

[gauravpundir231]

Hi All,

Can anyone please explain "is PBR  capable of influencing return traffic" or what is the fate the of return traffic.

Any document on Set commands in PBR or can explain here.

As a general answer if you wanted to influence the path traffic takes both ways then you would need to apply PBR at both ends for that to happen.

Thanks Jon.

any doc on set commands and their usage. i tried on google however not able to understand exactly

If PBR does something like setting a route tag or community string, or prepending routes in a BGP route path advertisement, it can influence the path for return traffic. As Jon notes, though, generally other routers would need PBR to "react" to what another PBR router did to influence their route forwarding. An exception, though, would be something like the prepending routes in BGP.
