[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [FW-1] Two ISPs Questions
If you are just looking for increased speed, you will benefit the most from getting two connections from the same ISP. Most ISPs should be able to guide you through the process of binding the two T1s together. It depends on your hardware and your ISPs hardware/policies on how this will be accomplished, but should not be a problem to get configured. If you are looking at two T1s, you might also want to look at getting a DS3 with 3MB of traffic available. Cost wise it is generally not much more expensive than two T1 lines, and telco generally respond a lot quicker to DS3 customers problems than T1 customers problems. If you want some increase in speed but are also looking for increased redundancy, then getting a T1 from a new ISP and then running BGP will provide redundancy, but may provide a limited increase in throughput depending on the ISPs you choose. But in some rare cases having a second T1 with a second ISP could provide no bandwidth increase at all. Also, if you are looking at redundancy, it has been my experience that outages are generally caused by the local loop (T1 line) going down, not by the ISP itself going down. If you have two T1s going to different ISPs for redundancy instead of to the same ISP, it is still likely that both T1s could go down together if your local telco has a problem. All said and done, I would recommend getting the second T1 (or a new DS3) from the same ISP if bandwidth is your driving motivation. For what its worth......

It might be easy in short term to go with one ISP but in long term, you will benefit by going with two different ISP's. Just my two cents.. -Tasawar CISSP, TCISA, CCSE-NG, MCSE+I, CNE, FCSE, CCNA http:/www.securenode.com -----Original Message----- From: Mailing list for discussion of Firewall-1 [mailto:[email protected]]On Behalf Of Miller, Curt A. Sent: Monday, August 18, 2003 11:13 AM To: [email protected] Subject: [FW-1] Two ISPs Questions We have reached the limit for one T1 for our firewall. We are looking at putting in a second T1. Can someone give me advice on if is better to go with two ISPs or one ISP? If we go with one we can IMA the two T1s together. If we go with two how do we do this? Would something have to be done on the ISPs side to be able to use both? I guess I need total advice on doing this.
