[c-nsp] prefix-list/route-map quandry

[Charles Sporkman]

Hello,

I'm getting a little bit stuck here.  I spent the better part of
friday evening looking at the "IOS Essentials for ISPs" book and at
the resulting config and just walked away scratching my head...

What I want to do seems pretty simple (I think).  I have two
upstreams.  No problems with announcing my prefixes, everything's
fine.  Inbound, they are both giving me default, and one "ISP X" is
giving me customer routes as well.  "ISP Y" is my preferred provider. 
I want to use "ISP X" for:

-backup if I lose "ISP Y"
-I want to send any traffic destined to their customers to them directly

So in essence, I want to pad the incoming default route from them, but
not the customer routes.  I'm doing the following right now, and not
seeing any customer routes in the table (but they are being received
according to "sh ip bgp x.x.x.x"):

 neighbor 10.1.1.2 remote-as 6939
 neighbor 10.1.1.2 description Hurricane Electric
 neighbor 10.1.1.2 password <removed>
 neighbor 10.1.1.2 update-source Loopback0
 neighbor 10.1.1.2 version 4
 neighbor 10.1.1.2 soft-reconfiguration inbound
 neighbor 10.1.1.2 prefix-list bgp-out out
 neighbor 10.1.1.2 route-map he-def-prepend in
 neighbor 10.1.1.2 route-map prepend-us out
!
ip prefix-list he-match-def permit 0.0.0.0/0
!
route-map he-def-prepend permit 1
 description prepend on default route only
 match ip address prefix-list he-match-def
 set as-path prepend 6939
!

I'm totally new to prefix-lists, somewhat rusty with route maps, and
pretty much lost on using them together.  What's gone awry here?  The
rule is working as far as prepending an extra hop on the received
default, but the other routes are not showing up anywhere.  As you can
see, I currently have no inbound filters (yes, I don't want to do that
permanently)...

Just so we can all see that I am hearing their routes:

router#sh ip route 216.218.186.0
% Network not in table
router#sh ip bgp 216.218.186.0
BGP routing table entry for 216.218.128.0/17, version 1868955
Paths: (1 available, no best path)
  Not advertised to any peer
  6939, (received-only) <<---
    209.51.171.25 from 209.51.171.25 (216.66.23.98)
      Origin IGP, metric 1, localpref 100, valid, external

I'm probably doing something really stupid and blaming it on the route
map.  Just not sure what I'm doing that would stop the received
routes...

Thanks,

Charles
