If you specify "password" options for a BGP peer, it will enable TCP_MD5. Of course in FreeBSD it's a bit clumsy and you have to use setkey(8) to set the keys. But it works. The reason for setkey is just because the software (quagga, bird,...) didn't grow a proper key management integration on pfkey2. Would be easy. Might be needed soon anyway;-) Not having looked at the particular openbgpd patches in our ports tree I would almost expect there can only be a minor issue that it would stop to work for non-protected peers once MD5 support is present in the kernel and that should be easy to spot. Unfortunately Doug didn't say from where he updated to this December 8-STABLE to see if it could be the MFCs of the MD5 changes by Attilio could make OpenBGPd as in ports cranky? /bz -- Bjoern A.
