Description

Add an option to limit the allowed prefixes in OpenBGP.

It would be a global option, but would be located at the bottom of the config file and include things such as:

deny from any inet prefixlen > "x"
deny from any inet6 prefixlen > "y"

Where x and y would be the maximum prefix bit length allowed. Usually the standards are to block anything larger than 24 bits in IPv4 and 48 bits in IPv6.
