I know if is not possible to have a full routing on ex3300(low memory for it) , but i never tried to do a default router on it( with EFL licence and software above version 12) I have many bgp session with cisco 3750 switchs.. Traffic about 2gb on it... Have a peer( ebgp customer) with a acx2000( i know it have 10gb port) we send to this router a default route only... And it have 1.5gb with us and more 1gb with other link provider... Enviado via iPhone Grupo Connectoway
