Hi,

I solved with the following mangle rule:
where xxx.yyy.www.zzz is one of my own prefixes

I'm 100% sure the problem is the GRE.
I just made a simple test by forcing a prefix to enter via a fiber provider and exit via another, reproducing thus the asymmetric routing: the problem doesn't happen.

Hi everyone, I'm running a multi-homed provider and recently subscribed an anti-ddos solution which allows me to announce my /24 prefixes through their network via GRE tunnel so they can scrub the traffic. Basically, the traffic enters my network through the GRE tunnel and exits through my fiber pro...

Also, your inlet air temperature seems to be 62C, maybe something else has failed?

Hi,

are you 100% sure that it refers to 'inlet' air temp and not some different sensors on the routerboard? Because the room can't be at 62°C (144°F)... unless their office is located in hell

Hi, I have a CCR1036 running v6.42.4 and configured with BGP routing. It works perfectly, except I can't reach the outside directly. For example, I can't simply ping 8.8.8.8 : [admin@router] > ping 8.8.8.8 SEQ HOST SIZE TTL TIME STATUS 0 no route to host 1 no route to host sent=2 received=0 packet-l...

Hello,

after 6.41 I had to configure it as a router, there's no way to configure it as a switch (with master ports etc.)

Also, I need the firewall for my purposes

Hi, I'm running a series of CSR2015 with very similar configuration. One of them suddenly locked down, with nothing but incoming traffic on the display (which looked like it was running anyway). I had to hard reboot it and it worked again without further problems. Can someone help me understand if t...

The solution offered by MikroTik: If you are lucky, it will be solved with RouterOS v7!

I was aware of that thread just hoping there might be some alternative solution... or even an hack

Currently recursive routing will not work if gateway is link local address.

thank you mrz. so what's a possible solution?
I have other peers which allow BGP through a /126 or /127 ptp, but this one provider is not going to allow me.

Hi, I'm running v6.38.1 on a CCR1036 and have the following scenario (real addresses and AS obscured for privacy): - loopback address set on a bridge /ipv6 address add address=aaaa:bbbb:ffff::1/128 advertise=no interface=bridge_myprovider_ipv6 - static route to provider's loopback: /ipv6 route add !...

Thank you very much! I'll give it a try as soon as I can

Hi, I've built a lab setup with four routers, each of them running the latest ROS release (6.41.3). This is the scenario: R2 / \ C1 -- R1 R4 -- C2 \ / R3 I've configured BGP so that R1 and R4 are my endpoint routers (i.e. R1 is default gateway for C1 and R4 is default gateway for C2), and R2+R3 are ...

I think I nailed it.

The provider handled me a /127 PtP address. I found on another topic that this prefix isn't supported on Mikrotik as default gateway. I changed the address with a /64 and it worked perfectly.

Hello, I'm doing BGP IPv6 peering with my fibre provider. I can reach their Ipv6 PtP address, but their router (an Alcatel Lucent) is announcing the PtP address as default gateway. This is marked as unreachable from my side. Another peer, from the same provider but using a Juniper router, is announc...

Hello, I used to set some ACLs on CRS226 cloud switches, which allowed me to restrict access so that only a given IP and a given MAC could make traffic on a given switch port. It worked perfectly and was very easy to setup (https://wiki.mikrotik.com/wiki/Manual:CRS_features#ACL) Unfortunately the CR...
