Hello, You have applied PBR to the fa0/0 interface on R1 for inbound traffic. What about the returning or response traffic from R3 ? I think the returning traffic use the link between the R3 and R1. It doesn't use the link between R2 and R1. And it couses asymmetric routing in this case. What do you think about this situation Keith ?
Yes. If EIGRP is running, R3 would use the 512K link to forward traffic to the PC. So would R2. :) It this topology that indeed would result in asymmetrical routing as the reply path would be different from the initial path.
keith here i stuck, what if router 3 has pc hanging on router 3 and you want to route traffic to reach PC 1 on router 1 will the traffic goes R3>R2>R1>pc1 ? i have tried but the traffic goes like this R3>R2>R3>R1>PC1 how can i change this behavior
Traffic from router 3 PC should go R3 > R1 > PC1 since it has the faster link. If you wanted it to use the other path R2 > R1 then you would need another policy route to specify so
yep. nice video. Great stuff. Straight and to the point.
PBR configuration starts at 6:46
Great job Keith. Keep up the excellent videos.
Superb. Cheers Keith.
Keith is a True Champ
Good stuff and clear message/information . Keep up the good work
Thanks a lot Keith. Always helpful.
Needed this at work. thanks alot.
thanks Keith, it was so clear and useful
nice explanation and lesson.thanks
Thank you Keith
Nice explain thanks Dear

what do we need to do to change the return traffic?
Great job👍
thanks, helped a lot :)
Glad it helped, Sebastian!
Thank you Keith for the great video
Are the serial interfaces actually serial? Like SSH?
Thanks Keith :-)
Can this concept applied to other routing protocols like bgp?
Outstanding explanation ..but what will happen if S2/1 of R2 goes down ? will drop all the UDP packets or it will use another link for UDP ?
Good question,
Will not drop UDP packets, instead it will use the normal path, which is for both UDP and TCP traffic in the regular path.
Nice to see that!.
you could make a video of how to configure vyatta or vyos closing a BGP session
Route map is implicit deny then how the ICMP suceed without permit rule ?
Nice !!! Can i use this in bgp ?
keith here i stuck, what if router 3 has pc hanging on router 3 and you want to route traffic to reach PC 1 on router 1
will the traffic goes R3>R2>R1>pc1 ?
i have tried but the traffic goes like this R3>R2>R3>R1>PC1
how can i change this behavior
