Lane, What about on Cisco's tweaking the global command "ip tcp synwait-time X" so you don't have to wait so long for BGP to notice that the TCP session no longer exists, there is probably a parallel command on Junos. I haven't tried it on BGP, but I would think that it would make BGP (and any other protocol that relies on TCP sessions) much more sensitive. marty > -----Original Message----- > From: [email protected] [mailto:[email protected]]On Behalf Of > Lane Patterson > Sent: Friday, January 12, 2001 1:08 AM > To: '[email protected]' > Subject: FW: BGP keepalive/holdtime at GigE exchange > > I am looking for operational BCP feedback on common practice for tweaking > down BGP holdtime/keepalive across GigE exchange points, since a peer > could go down on the other side of the GigE switch without a > corresponding adjacency change seen on your BR.
