Best bet, would be to run BGP with both providers. If this is not an option, ask each to advertise the block of IPs from the other. You do NOT want to go and assign 2 IPs to each server you have, the reason for this, is that with 2 IPs, you'll end up with a round-robin DNS. If one T1 is down, then 1/2 the people trying to reach a server on your network will fail. BGP isn't too difficult to set up, and contrary to popular belief, you can still do this on older/smaller hardware. Just do the announcements, don't worry about taking full tables from either provider. You can get away with simply setting 2 default routes and letting your router bounce the outbound traffic between the 2 lines. -- Troy Settle Pulaski Networks 540.994.4254 It's always a long day, 86400 doesn't fit into a short -----Original Message----- From: owner-freebsd-isp@FreeBSD.ORG [mailto:owner-freebsd-isp@FreeBSD.ORG]On Behalf Of Andrew Ryder Sent: Tuesday, September 05, 2000 1:48 PM To: freebsd-isp@freebsd.org Subject: question about Dual NICs If I have two T1s from independent providers with two different blocks of IPS, two 3c905-TX cards, two different IPs For redundancy reasons, what's the best way to go abouts this? Have each card run seperate IPs (one from each T1) what discerns between the two so it knows which routes (besides routing tables) to use? Anyone have a similiar solution? We have two T1s - one for client bandwidth - one for servers (dedicated) which I want to combine just in case everything goes down. How does DNS then go? Dual A records? Thanks.
