Intresting action here.. Two ISPs , two MikroTik Routers. Each one is receving one providers full BGP tables. Both routers have 4 differant prefixes listed to advertise (all setup with NO for sync).
This works fine, and if you reboot one MT, everything is fine, all traffic hops to second MT, great. Somtimes on provider B, the BGP session drops, and then immediatly reconnects and starts receiving routes. The issue, is that the prefixes (again both provider A and B are sending out the same prefixes without prepends), these prefixes completly disapear from the internet routing table! I.e. even though Provider a is still connected and never lost a BGP session, all inbound traffic stops, and on other BGP MTs in the planet, their Prefixes are NOT shown, until we do a resend all on Provder A.
Thoughts, suggestions?
