I agree here. If we can roll new md5 keys without session resets I am all for it. I believe Juniper needs to fix their implementation. Especially with md5 rolling out network wide for quite a few networks. If an employee leaves and we have to reset the md5 passwords for the entire network with a hybrid of Juniper and Ciscos, I would love to not have to bounce all of my sessions. I think your best bet is to call JTAC and ask for a feature request. -Chris -----Original Message----- From: Sean Donelan [mailto:sean@donelan.com] Sent: Saturday, April 24, 2004 4:32 PM To: sthaug@nethelp.no Cc: nanog@merit.edu Subject: Re: Juniper failes to change keys (More MD5 fun: Cisco uses wrong MD5key for old session after key change) On Sat, 24 Apr 2004 sthaug@nethelp.no wrote:

But as long as the session *is* reset anyway, the current situation is extremely confusing - the log messages (on both Cisco and Juniper) give no indication that the invalid key in question is for an *old* BGP session, no longer active!

That's why I hope Juniper will fix their implementation not to reset the session and to stop using an old key. Once the key is changed, all new packets (including new packets for old sessions) should use the new key, not the old key. You think the bug is on Cisco's side, I think the bug is on Juniper's side. Hence interoperability.
