I am trying to figure out why the route with the localPrf of 110 is chosen as the best route over the one with the localPrf of 200 ? I was under the impression that the route with the highest local preference is usually chosen. Any help appreciated.
BGP table version is 3, local router ID is 172.16.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
*> 0.0.0.0 10.0.0.4 110 0 100 i
* i 10.0.0.2 200 0 100 i
* i22.214.171.124 126.96.36.199 0 100 0 i
*> 0.0.0.0 0 32768 i
It seems to pretty clearly be two advertisements for the same prefix.
Since the next hop is in the same subnet I am wondering if there is something in the peering arrangement that is affecting this. Perhaps it would be helpful if we could get the output of show ip bgp 0.0.0.0 and perhaps the complete bgp configuration.
 it is a little easier to read in the file since the spacing of the fields shows relationships that are not so obvious with the acsii rendition of spacing in this post.
I'll have to bow to Giuseppe's expertise on this matter, but I thought the sychronization with the local IGP only affected if the route was announced by BGP. I didn't think it affected whether or not the route would be picked up by the local routing table for use. (But I'm a novice at BGP)
I was thinking you might want to go one more step up the decision ladder. Is the next-hop (10.0.0.2) a reachable IP from that router?
If not, then you may need to add the route, or configure next-hop-self..
Please let us know what you find, I'm curious as to what the problem is.
According to the output you provided, the issue is with synchronization. You need to configure "no synchronization" under the bgp process to make the path with the local preference of 200 preferred over the other.
