I ALWAYS start with the CYMRU secure bgp templates, found here: http://www.team-cymru.org/ReadingRoom/Templates/secure-bgp-template.html
I personally would not recommend a firewall in front of your router, sufficient ACL'ing should be enough for securing the router itself.

Our routers are running BGP so I'm interested if there is any way to secure them without interfering with BGP? Is it normal to put a firewall in front of the border routers? I'm concerned about DDOS attacks mainly....although we haven't had any, I don't welcome them..... Brandon
