Hans - as I understand it, the networks advertised by the 'network
x.x.x.x' bgp statement are advertised to EBGP peers, and when routes are
advertisedto ebgp peers, the next hop is set to the ip address of the
advertising peer, not the igp next hop.
When eBGP routes are advertised to iBGP peers, the next-hop is maintained
(i.e. the next hop of the eBGP peer whom advertised the route). This is
often problematic as the eBGP peers IP address may not be known inside the
IGP. In this case you can change the next hop to that of the iBGP
routerusing the 'next-hop-self' command.
hope that iswhat you are looking for
