BGP reboots mikrotik & prefix-list doesn't work

RouterOS General
1

Hi
I have a big problem with BGP on mt 2.9.8
I can successfully connect to peer and establish a session but after some time router reboots. This happens every time reveived routes counter hits above 40000.
Not to mention prefix-list doesn’t work.
I creeated one to reject everything incoming (0.0.0.0/0 0-32 reject)
but it stil downloads lots of routes.

Any ideas?

Routing or routing-test?

Routing. Don’t see routing-test in 2.9.8

It’s on the ‘downloads’ page. Here is the direct link http://usa2.mikrotik.com/download/routing-test-2.9.8.npk

What are the specs of your machine? It sounds like either you don’t have enough processing power or enough memory. We are using a P4 2.4 with 512 megs of ram, accepting routes from 2 providers (172000+ each) and using about 130 megs of ram for BGP. Although people say it can be done on 256 megs of ram, I personally would highly advise you not to do it with less than 512 megs.

I have a bgp problem about prefix-list too. I have a mikrotik that connect to 2 Cisco routers. One of the routers is connected to the Internet Exchange Organization (we call it router1) and the other one (we call it router2) is connected to 2 upstreams, the same IX Organization as router1 and an international connection.

I have 2 network, network1 (2 block of Clacc C Network) that interchange with my IX ORganization and network2 (4 blocks of Class C Network) that broadcasted to the internet.

My problem is when i use bgp to advertise and receive routing from both of the router, i got the route to the Internet Exchange from router1 but those route is also broadcast to the router2. so in router2, there are 2 ways to connect to my network, from router1 or from the mikrotik itselfs and both is acknowledge as the best path. I can not arrange the weight of bgp on my mikrotik since it is a router package, not a router-test.

Anyone can give me a clue about what is happened? Is there a bug at prefix-list on mikrotik?

Use routing-test.
