Hi there,
Does anyone know what the limit of the routing table is on the CCR1072-1G-8S+ ?
For instance, my current HP HSR6602 can have 4 million routes at max.
I am looking to replace this HP with possibly the 1072 as BGP router.
Hope to hear from you!
Chris
there should be no problem with serveral global routingtables in the CCR. I cant tell how manny 100% on the 1072 - i have never used it for eBGP - but the 1036 can handle 2 full global tables, at low cpu and memory usage with no problem. Maybe the 1072 support a full global table at each port? (just a tough)
Btw - do you need 4.000.000 routes at your router? 
4M routes, is like all global IP’s as /22 net’s (1000 ip’s in eatch route) Even with an REALLY BIG internal /32 table from ppope etc - you should segment to the world - and not have that much routes in one router.
Thank you for your answer.
Max theoretical number of routes depends on installed amount of RAM:

So you are replacing a 20000$ dollar router supporting 4 million routes with Mikrotik 1072… Sounds legit.
On our 1072 we have over 2 million routes and it handles it without a problem, I don’t see 4 million being an issue.
One thing to keep in mind though, if you are waiting to use this unit for BGP, bgp is a single threaded process, so sometimes convergence can (or route filter updates) can take a long time to make it into the FIB.
