RE: 2 line: the best solution ?
Have you considered putting voice on one of the links and data on the other? If you mix voice and data on the same 64-Kbps link, you may have too much delay for the voice. On slow links, serialization delay is a significant factor. Let's say someone starts an FTP transfer at the same time the president of the company starts a voice over IP (is that what you use?) call to the company executives. FTP uses 1500 byte packets. While the serial port it outputting a 1500-byte packet, (which would take 188 milliseconds), your voice packet is waiting. Since one-way delay is only supposed to be 200 milliseconds for voice, you're already in trouble. You could use fragmentation to chop up the 1500-byte packets. Both PPP and Frame Relay support data-link-layer fragmentation. (not sure what you have) You may want to study your traffic a bit more before designing a solution Priscilla >-Original Message- >From: Cristi Piatnitchi [mailto:[EMAIL PROTECTED]] >Sent: 18 October 2000 14:56 >To: [EMAIL PROTECTED] >Subject: 2 line: the best solution ? > > >Hi all > >I have 2 leased line (64kb) one of them working with voice and data and the >other one just with data. 2 Cisco routers.

RE: 2 line: the best solution ?
Hi all First,thanks for your help. I have studied the CISCO docs but no results These are the two routing lines for my routers ip route 10.2.44.0 255.255.255.0 192.168.39.98 90 ip route 10.2.44.0 255.255.255.0 192.168.38.98 100 It worth saying that the backup line is always up.It caries voice also. Does the backup config work even for frame relay links (one of my serials could be a FR link) 1) I want to ask you if the routes should have the same cost ? 2) Shall I configure the router from the other end with backup config too ? 3) How does it work this configs ? I don't understand if both links will work in the same time when the first one reaches the level specified in: backup load 70 50 70 means that the second line is activated at 70% of the main line 50 means that the second line is deactivated at 50% of the main line Thans in advance for help Please see below for scheme On Wed, 18 Oct 2000 15:54:33 +0200, Andrew Larkins wrote: > backup interface does not just refer to dialup.

RE: 2 line: the best solution ?
backup interface does not just refer to dialup. It is a common practice to use this kind of dialup backup as it is cheaper. -Original Message- From: Cristi Piatnitchi [mailto:[EMAIL PROTECTED]] Sent: 18 October 2000 14:56 To: [EMAIL PROTECTED] Subject: 2 line: the best solution ? Hi all I have 2 leased line (64kb) one of them working with voice and data and the other one just with data. 2 Cisco routers. I want to set-up these lines to work toghether. Which one is the best solution: router - router | | \-->Multiplexor--Multiplexor
