It's not necessary, but I think it's good to do it: instead of letting the router to choose the Router-ID, choose one yourself and propagate it through your network.

This way, you can always get (to the router that) you want. (read this like the Rolling Stones would do it)

jprietove

Happy to see that this bug has been solved in v.7.1.1

Now, when enabling R4 it get elected as DR and it's as fast as ffrouting changing R1 from DR to normal router.
And also, R1 status change from "ExStart" to "Full".

The particular use case is to prevent routes advertised by Neighbor A due to a bug from spreading further to the network

I think you can use two different OSPF Instances in your router, using redistribute-other-ospf. With different OSPF Instances, you can use ospf-filters between them.

You use MRU and set it to 1500. L2TP slices the packets in one side of the tunnel and the slices can be reconstructed at the end of the tunnel.

I'm afraid that bonding is hardware offload only in crs3xx series. In CCR series bonding is done on software. But I've reached 2gbps with bonding on ccr1009 in a transit router. I mean, different IP addresses for source and destination. So there should be a problem in your setup. Enviado desde mi Mi...

In ipv6 usual prefix is /64. So a local attack will not be filtered by the rules proposed and the number of possible hosts is 2^64 because ipv6 addresses are 128 bit numbers.

Yes, you can use the same pool for all the profiles

I have done several tests with GNS3 using CHR 6.44.2 (stable) and as long as the router has enough memory, it doesn't crash. In my tests, the attack 'steals' around 180 MiB. Using a CHR with 256 MB, system resources shows a total memory of 224 MiB and free-memory of 197 MiB before attack. During the...

I use GNS3 that is more than a diagram tool and you can also try https://draw.io

I've used that configuration lots of time. No problem at all. Look your cables, connectors, etc. It should be almost 'plug and play'

jprietove

I have just tested this beta and I confirm that with 300 Mb RAM the router's memory doesn't fill. A CHR with 300 Mb of RAM with OSPF-v3 has 237 Mb of free-memory and during the attack it keeps on around 200 Mb.

Hopefully this fix will be in long-term and current branches soon.

This sounds almost exactly the same as what MikroTik will be fixing on Monday.

What would be characters 9, 10, 11, 12 of the md5sum?

Sorry @maznu but I don't get the same md5sum you expected. Maybe mine is a different but correlated attack

jprietove

I've done my own investigation and I think I can reproduce the problem. First it is important to note that the target of the attack needs not to be the Mikrotik itself: if it is forwarding traffic from an attack, its memory can exhaust and eventually it will reboot. So my lab is similar to this: an ...

It is not strange, it is called hexadecimal: In the address 2001:db8::33/126 I will look into the last '33'. As it is HEX, in Binary it is 001100 11 The last two bits are not belonging to the prefix, so the prefix is 001100 00 If I write it in HEX again it is 30, os the prefix is 2001:db8::30/126 Th...

I don't know exactly what are you asking in this post. One port can be 'tagged' and 'untagged' at the same time for different VLAN-id. Hybrid port is the name.

jprietove

What is happening Your router are doing bonding and bridging by software, thats the reason your CPU goes so high. As your traffic is going from only one point to other, the MAC-addresses of all traffic will be the same so if you use layer2 hash, only one path will be choosen. Improving a little Bet...

Check if there are several routers with same Id. Check also that router up address in loopback interface is correct, with /32 and network equal to address.
