without wishing to repeat what can be googled for.. putting acls on your edge to protect your ebgp sessions wont work for obvious reasons -- to spoof data and disrupt a session you have to spoof the srcip which of course the acl will allow in
This is why this helps for eBGP sessions only the peer is also protecting its borders. I.e., if you know the peer's network has spoofing-prevention enabled, nobody is able to spoof the srcip the peer uses.
