Issue with Route Map in EIGRP Lab

[ALI12]

Hello Team,

I've set up an EIGRP lab in GNS3 between two sites (Site A and Site B) with dual ISPs. Everything seems to be functioning well 

A traceroute from PC-A (IP: 10.66.5.2) to Core-B (IP: 172.16.5.1) goes through ISP-1
A traceroute from PC-A (IP: 10.66.5.2) to PC-B (IP: 172.16.5.2) goes through ISP-2

However, when I applied a route-map to force traffic from PC-A to PC-B through ISP-1, it didn't work as planned.
I've attached the configuration details for reference.

Could anyone help me identify what's missing or misconfigured?

Thanks in advance!

Core-A:

interface Ethernet1/0
ip address 10.40.40.3 255.255.255.248
ip policy route-map RMAP-5
duplex full

router eigrp 10

network 10.66.3.0 0.0.0.255
network 10.66.4.0 0.0.0.255
network 10.66.5.0 0.0.0.255

ip access-list extended MA-V5

First of all you’ve applied the route map to the wrong interface it should be applied to the interface of the original source (loopback)
also please remember PBR ONLY affects the traffic towards the destination not the return traffic as such you have the potential to incurr asymmetric routing

Hi @paul driver 

I wanted to thank you for your continued support.

After applying the route map to the interface of the original source (E1/1), everything is now working normally.

Thanks again for your help!
