BGP Advice

Hello,

I'm currently in the progress of transitioning our organsiation away from a Managed router service (BGP w HSRP) to running our own BGP AS and peering initially with one UK Tier 1 ISP and potentially others in a multi-homing configuration within the next 12 months.

I'm looking for advice on BGP best practices for these configurations and any potential advice in regards to design or what should be key points to get right from day one.

I'm quite happy with eBGP and iBGP in general and will probably run an IGP between BGP peering routers once we get to that stage, I'm also aware of some key best practices like sending RFC1918 addressing to Null0 etc.. (blackholing RFC1918) as well as preventing spoofing with RFC2827 filtering as well.

Are there any other common best practices that should I study up on?

Would a firewall feature set be required for an edge BGP router to secure it from an attack or are common ACL/Rate-limiting combinations enough in other people's opinions?

Many Thanks,

Dunc
