Hi

The default route could be used, but the problem here is that next hops
are resolved by more specific routes that arrive through BGP, so you get
a cycle.

One solution is to put BGP routes to a different routing table than
default route / IGP routes and use 'igp table' option in BGP protocols to
specify the second table.

Another workaround is just to override gw or bgp_next_hop in the import
filter, as you already found.
