Change Router Gateway BY bgp community

[admin@atrinnet.net]

Hi i have this diagram

If prefix 192.168.10.0/24 have tag 50 gateway set Edge A

if prefix 192.168.10.0/24  have tag 100 gateway set Edge B

How can do this by vrf ????

check PBR with BGP example : by the way what device model and code running the router ?

Hello admin@atrinnet.net 

What is the protocol between Client Router and Edge Routers A and B ?

By route-map, no ?

route-map XXXX permit 10
match tag x
set vrf y

Apply route-map in ingress between client routeur and its Edge routeur.

Hmm 

Try this way 

Route-map VRF-A permit 10

Match tag xx

Set vrf VRF-A 

Set next-hop <IP> <<<- apologies use set interface not set next-hop' since set interface is not vrf aware (not check IP in vrf rib)

Do same for VRF-B 

Note:- run this in lab before apply in real network' some router not accept set next-hop/interface

Hello admin@atrinnet.net,
Use Policy-Based Routing (PBR) with route-maps to match the tag and direct traffic to the correct gateway within the appropriate VRF.
- Tag 50 → route-map → set VRF → forward via Edge A
- Tag 100 → route-map → set VRF → forward via Edge B
This allows the same prefix to be handled differently based on tag, using VRF separation and route-map logic.
