Can anyone suggest clues as to a reasonably successful way to handle receiving an IX /24 over both OSPF and BGP?
If ospfd has to be restarted and bgpd gets to install the /24 before the new ospfd, the nexthops within that subnet become invalid. I couldn't think of a way to recover from this short of stopping both routing daemons, then restarting ospfd and bgpd in that order (bouncing all the e-bgp which I'd rather not if possible).
