question 1 i have a null route for 4.4.4.0 255.255.255.0 in one router and the other as a null router for 5.5.5.0 255.255.255.0 then i network the address into bgp to advertize out. that is why the isp router has routes to the loopback address. question 2 that is exactly what i am trying to do. the community that is shown is what my isp uses to set the local preference. thats not the problem. the problem is on the routers, without the tunnel (not running ibgp between the routers) the router continue to search for the orgin of the local networks that are configrued. with the tunnel and while the tunnel is working the end routers complete the map and finish finding the orgin of the local configured network. but then bgp starts to look at the tunnel and find "recursive routing" as the debug message puts it. it temp disables the tunnel, although the inter show up/up. cuaseing the bgp connection to disconnect and then start to the seach for the orgin on the local networks. ...

I attached the same info: but i wanting to advertise the same address out at a different site using the same AS number. in about two months we have a test fail over down time window. so i would like to have the other site already advertizing the address but with a lower community so the isp will not use it unless we remove the primary router. i am thinking this will allow for a faster failover instead of turning off one router and turning on another and hopfull will advertise without problem. this will also allow me to test and verify the bgp connected to the isp is working and advertising correctly.
