Re: Issue with received bgp routes in ipv6 [SOLVED]

Hi,

I don't believe it is incorrect for using the link local address.

We peer with Lonap in the UK and it appears to work fine.

Have you allowed fe80::/10 in your IPv6 firewall (input firewall rule)?

The only way I found to be able to handle SYN Flood attacks, was to disable Route Cache (which introduces other problems though...)
We have route cache disabled on IPv4, what issues has it introduced that has caused you problems?

Re: MPLS - Labels dropping after outage

We have this issue not caused by MPLS but by OSPF. Occasionally after an outage, we are missing some OSPF routes for loopbacks. Our VPLS tunnels are between loopbacks of course and so if we are missing a /32 route in either direction it doesn't come up. The OSPF route that is missing always appears...

CCR – BGP+OSPF – Weird latencies

Ever since we have installed these routers 4+ years ago, we have had weird latency issues. This is on a very lightly loaded network, each router not passing more than 100Mb on average. We have 4 Mikrotik routers in total, all connected to different upstream providers with BGP. Within our own network...

Re: CRS317 High CPU [SOLVED]

Hi Marco,

Something in your config is causing it to process packets in software, the CPU has a 1Gb speed bottleneck.

I would start by taking a look at this page:

Re: CSS326-24G-2S+RM hangs until power cycle

When we had ours, we turned off flow control on the switch. We also have a policy of doing this on all devices too, however it could have been missed on some devices (unlikely, but not impossible).

So to conclude, turning off flow control did not stop the issue for us.

Re: RouterOS v7.0 beta1 - when?

There is obviously a huge stumbling block as to why a kernel upgrade has not happened, either in a 6.x version or the unicorn v7. Let’s not forget that Mikrotik is mostly made up of open source software, maybe one or more elements can’t be upgraded to a more recent kernel? My guess is that it’s fast...

We have not advertised v7 as a version. The first post in this forum thread is by a user. MikroTik only mentions v7 if there is some feature, that can't be implemented because of kernel limitations. In that case, it's technically not possible to make something until we have new kernel. Other than t...

Re: MPLS LAB Mikrotik as PEs and cisco as LSRs

If you can ping web-sites, but you're unable to visit them, it's most likely an MTU issue from experience. On the Mikrotiks you need to ensure you have an MPLS MTU of at least 1530 to allow an MTU of 1500 on VPLS. I think you need to setup that even higher if you have tagged ethernet on the VPLS... ...
