If you are using bgp, then you shouldn't have a default route. Do you see routes from both peers? bgpctl show should give you something like:
T-LEVEL3 3549 60101591 399386 0 04w1d23h 552098 T-COGENT 174 26910070 397509 0 06w2d20h 548495 the last column is how many routes were received from each peer. "bgpctl show rib selected" will show you the routes, and their next hop IP. Try to traceroute to multiple places, some should go over Cogent, and some should go over Level3. You can also look up some public "looking glass" and see where your routes are showing up. Once you have outbound connectivity from both, and both show connectivity to you, then things should work fine when you disconnect from one peer. However, re-routing is not instant, this may take 90 seconds or even longer. Using a private AS when connecting to two different transit ISPs is a bit surprising.
