Trying to setup a Two BGP session with 2 separate routers that provide internet access.
The 3 devices (PA, router1 and router2) share the same network 10.9.9.0/25.
BGP session 1 : PA <--> Router1
BGP Session 2: PA <--> Router2
the two sessions seems working fine when activating them individually, however when trying to establish the 2 sessions simultanialsty, one of them is stuck in active/openconfirm
I can't figure it out

Hello Wael.Hedhli,
OpenConfirm State:
In this state, BGP waits for a KEEPALIVE or NOTIFICATION message.
From RFC4271.
Maybe you can check on the peer side for some information.
From the firewall side, I think you can set a packet capture on tcp/179 (tx/rx/drop).
And make sure there is no drop capture (that means no packet dropped by the firewall).
