+Subject: [PATCH] frr-reload: rpki context exiting uses exit and not end
+
+Issue:
+The rpki subcontext uses exit instead of end to exit.
+This makes issues with frr-reload in the way that frr-reload never exits
+rpki context until it reaches the next end statement. this also happens when
+parsing the configuration from vtysh.
