Check that the OSPF Router ID of the router sourcing the OSPF route is the same as the BGP Router ID of the router from which you are learning the BGP route (10.0.70.1). If they are not the same, then no synchronisation.

Subject: BGP route not synchronized -- WEIRED!
I have a problem with a router not advertising internal bgp routes to its
peers (exhibit1)
The route (188.1.2.0/24) is synchronized (exhibit 2) and the next hop is
reacheable (exhibit 3) but the router still does not accept the route as
synchronized (exhibit 4)
The router is running IOS c2500-js-l.121-5.T.bin. I am puzzled. Any ideas ?
R1#show ip bgp
BGP table version is 1, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal
Origin codes: i - IGP, e - EGP, ? - incomplete
