SD-WAN branches not reaching other branches through hub in an mesh VPN cluster

L0 Member

hey guys hello, i successfully implemented an SD-WAN full mesh between 1 hub and 3 branches.

each FW has 1 LAN and 2 WANs, WAN1 on ISP1 and WAN2 on ISP2.

to test the full mesh connection and force branches to reach each other through the HUB is removed ISP1 on branch 1 and also removed ISP2 on branch 2.

i checked the bgp fib on the hub i can find the LANs of branch 1(learned through ISP2 as i removed ISP1) and branch 2(learned from ISP1 as i removed ISP2), the problem is that the hub is not redistributing the routes to both branches the fib of branch 1 don't contain branch 2 networks same for branch 2 fib it doesn't contain branch 1 networks. any idea about this problem ?
