<DIV><FONT size=2>I have a PC ( network actually, but let's just keep it
simple. ) that has two T1 connections </FONT></DIV>
<DIV><FONT size=2>to two different ISP networks. Both of the T1 routers ( Cisco
1720 ) are running BGP as set</FONT></DIV>
<DIV><FONT size=2>up by the ISP people. The </FONT><FONT size=2>network
</FONT><FONT size=2>is set up so that the Class C addresses that </FONT><FONT
size=2>we are using </FONT></DIV>
<DIV><FONT size=2>come in on either T1. </FONT><FONT
size=2> </FONT><FONT size=2>Getting </FONT><FONT size=2>to my </FONT><FONT
size=2>network over either T1 from the internet is ok. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Going out is a different story. One option ( that I can
think of ) is to use a Linux box that has </FONT></DIV>
<DIV><FONT size=2>access </FONT><FONT size=2>to both T1s. I'd like to have
something ( BGP maybe ) that will let the system decide </FONT></DIV>
<DIV><FONT size=2>WHICH T1 to set up as the default route. Any machine on
the network will specify the </FONT></DIV>
<DIV><FONT size=2>linux box as it's default route. The linux box will decide
which T1 to use. </FONT><FONT size=2>Do I need to set up </FONT></DIV>
<DIV><FONT size=2>BGP... or is there something similar... but less
complex/powerful that </FONT><FONT size=2>I'd should use instead? </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>One of the ISP Techs said that I could run ihbgp ( something
like that ) between the two </FONT></DIV>
<DIV><FONT size=2>routers if I connected them up with a WIC card. Another ISP
tech said that I would </FONT></DIV>
<DIV><FONT size=2>need a different, dual port Cisco router that I'd plug both
T1s into. I don't know if either</FONT></DIV>
<DIV><FONT size=2>of them really knew what they were talking about.
</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I am 75% concerned with just Which Interface is up and
operational. I'm 25% concerned with </FONT></DIV>
<DIV><FONT size=2>which interface </FONT><FONT size=2>is better for a particular
conection or period in time. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I know that I can just </FONT><FONT size=2>set two default
routes but I never have figured out which one is used. </FONT></DIV>
<DIV><FONT size=2>If one of the routes is 'unreachable', does it always go to
the 'good' one or is it 50/50 or </FONT></DIV>
<DIV><FONT size=2>what? </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Any info would be appreciated. </FONT></DIV>
