Issue: Route cache overflow (x86/any) Description: When you have a 6to4, ipsec, gre or sstp tunnels your route will oveflow and stops IPv4 traffic. Reboot is only resolution. More information on the "How to reproduce" part. Versions affected: 6+ till 6.25rc7 How to reproduce: http://forum...

Hi,

I just installed the 6.24RC8 version from 19.12.2014 ~17:38. Issue is still valid. I'm really thing about migrate to VyOS of sth like that.

Hi,

I'm think that it is not depends on hardware, it is a software issue/bug.

Hi,

Yeah, it's because IPsec/GRE/6to4 interfaces. I'm writting it here and maybe someone from Mikrotik will take a look. I think that more people can be frustrated about this issue.

Hi, And reboot required, when the route cache will go over 65535 then all IP traffic stops.

Hi, I'm wondering when it will be fixed, I'm installing every new version od RouterOS for x86 and stil is the same -> route cache overflow. I've contacted the support about it, Maris reply me that "It could be related to gre over ipsec or 6to4 tunnels." and nothing, few supout was send by ...

drixster, will putting the AP in a bridge and run your stuff off bridge?
Bridge is always up.

Seems to be good workaround but I don't trust it.

Hi, There is a still issue with BGP (session only on ethernet/tunnels) and WLAN (no bgp peers), where there switch and someone is present on WLAN and then disconnect. After this, routing gets 100% CPU usage on RB433. Only way is reboot router. Support: Ticket#2011021266000179 (sent last supout.rif f...

Hi, Can someone confirm issue with IPv6 on WLAN? Always make 100% CPU load on RB433 with R52 wifi card. Config: WLAN interface on 2.4GHz, assigned a IPv6 address from /64 block, EUI-64 based on the interface WLAN Running radvd-like announce /64 prefix on the interface. No client connected <- this co...

Use routing-test instead normal routing, then you will be able to add IPv6 Network to the BGP

Fixed in 3.19

EOT

we need your supout.rif file to see the cause of the problem, forum reading is not enough. also - forum is not a support system, we don't read every post.

It's already investigating by Mikrotik support (Ticket#2008122966000358)

Yes, on wireless too. But on WLAN I don't have as much IPv6 traffic. Anyway, I don't see any influence on router's load.

Please try to make about 25Mbit on IPv4 and then on IPv6 and look CPU Load.

On WLAN traffic too?

Mail sent.

I think that they reading this forum, if not I'll sent it today evening.

Confirmed on 3.17@RB433, high load on pure IPv6 traffic.

Can someone fix it?

1. RB433 getting high load when the IPv6 traffic going over RB. With 2-3Mbps getting 99%. Normal work without IPv6 getting max. 5% Confirmed on 3.13 and 3.14. Confirmed on 3.15. Can someone check this on your own network, pure IPv6 traffic generates 100% CPU load, can someone confirm it or not? I t...

Dear all, I just configured a RB433 with 3.14 as BGP peer for IPv6. It's only getting few routes (aprox. 30) and seems to be working. I have found two problems: 1. RB433 getting high load when the IPv6 traffic going over RB. With 2-3Mbps getting 99%. Normal work without IPv6 getting max. 5% Confirme...

Hi

Do they know that there is a problem and going to fix it?

Hi all, I new user of MikroTik on RB433 and I have few questions about IPv6 setup. I have done a setup of IPv6 native link between Linux and MikroTik on Ethernet cable. Both sides are pingable from both sides. I have assigned each /64 on each interface (ether1/2/3 and wlan1). On ether2/3 and wlan1 I...
