Re: [isp-bgp] BGP Newbie Help - Config Review

Below is the config I have, but I don't think it is correct. I would like a
little help fixing it to do what its supposed to.  First, a little topology;
I have 2 T1s to Sprint AS1239 Atlanta that are to be load balanced as a
secondary route, and a T3 to UUNet AS701 that is to be primary route for
both inbound and outbound traffic.  I plan on getting full routes from UUNet
and No routes from Sprint (is this recommended?  Otherwise, I could get
partial routes from sprint)
How will you handle outbound traffic failover? Get default from Sprint? Get default from UUNet? Manual default to Sprint?

I have the following netblocks currently that I need to advertise:
204.180.198.0/23
63.169.171.0/24
Are they in your router at the exact mask length?

If anyone could be so helpful as to take a look and let me know what I
should change to make everything kosher, that would be great.
[I would group the two Sprint neighbors into a peer group.]

 neighbor z.z.z.z description UUNet ASN701
 neighbor z.z.z.z remote-as 701
 neighbor z.z.z.z version 4
 neighbor z.z.z.z distribute-list 30 out
 neighbor z.z.z.z send-community 701:110
 neighbor z.z.z.z maximum-prefix 150000 warning-only
I don't think 701:110 is a valid UUNet community. I think it's only 701:80, 701:100, 701:120, and then 701:1, 701:2, 701:3 for prepends.

Also, I see that your max-prefix line is warning-only, but it'll be essentially useless except to tell you the session is up. I'm getting 154729 prefixes from them at this moment.
