Questions abourt Routing

Hi,

i have some Questions about Routing with Mikrotik:

→ Can the CCR1036-12G-4S handle up to 3 FullTable BGP Session?
→ Are there any Documentations or best Practises about VRRP?
→ Why i cant buy CCR1036-12G-4S directly in Germany? On our Distributors is it always out of Stock but i need 2 of them.
→ Any Tips for RAM Upgrade? I want to add 8 or maybe 16GB ram in the CCR?
→ Are there also some known Tips and Tricks to handle 400k pps with TCP-SYN len=1,2?

Regards,
raz
