First Time setup

[redwolf52]

I am fairly new to routers, been playing with one at work for about 2 months. The office is moving and I will be responsible for setting up a pair of 3660 routers. I know that we will be setting up BGP for redundancy. I am trying to be as prepared as possible and I wanted to know of any config or ACL tips that I should study up on first.

Thanks in advance

you don't have to set up BGP for redundancy in all situations....is there another reason why you are wanting to set up BGP? Are you going to be multihomed to two different providers, with your own AS number?

Depending on what the situation is and who your provider is, they may provide you with what they want your BGP configuration to be. If you would like to do some light reading on the basics of BGP check out this link.....

What sort of information were you lookiing for on ACLs? Erik Rudnick, CCIE No. 9545

We are going to have multiple local routers going to 2 different ISP's. That is the reason for BGP.
As far as the ACL's, I was planning on copying the ACL on our current router over to the 2 new ones. I just want to check if there were a few tricks that I should be aware of when I try to modify the ACL's.

So basically I am looking for some tricks of the trade for a N00b setting up his first router.

Thanks

I'd recommend getting a good CCNA book, and learning about ACLs. It would probably be a good start for you. Network Learning Inc

I am up[ to my eyeballs in CCNA books. I understand how to construct the ACL, I was just talking about any specific things that I need to make sure I restrict.

i realize it is a slightly open ended question

Thanks for all your input

BGP can be a complicated protocol to use if you aren't familiar with it.

One thing I would do if I was you would be to tell your two ISP's only to send you the default routes, so you won't have to learn about filtering. Then just make sure that you advertise your public net blocks correctly.

Even if you have two isps, most of the time you can get away without using bgp. You could setup hsrp on the two routers, and make two equal cost static routes for your default gateway. Most of the time your isps will advertise your netblocks for you, so you wouldn't need bgp.

BGP requires a lot of overhead, and a good configuration. From a simplistic stand point, you shouldn't run BGP unless you understand a LOT about it. A simple ACL book won't teach it all to you.

If you want to learn it, it has it's benefits. You can do route preference, add new ip blocks, etc without having you isp configure their equipment on your behalf.
