Layer2 ovcer Layer3 Tunnel
by Andre Timmermann 17 Aug '15

Hi, I am looking for a way to do a layer 2 connection via a routed network. Arista is using VXLAN for that, but unfortunately my Aristas are not supported. The goal is to back up my direct fiber connection by this "virtual fiber". Unfortunately I can't get a second physical fiber here. Any software recommendation? Greetz, Andre

Cablecom and OVH speed problems since years
by Marco Näf 06 Jul '15

06 Jul '15

Hello Everyone I'm having speed problems when I want to download files with my 250mbit Cablecom home connection from OVH. The files are loading with a maximum of 300kb/s. A MTR shows that all data is transfered via a private peering directly from OVH. As it's very difficult to get someone from the Cablecom network departement via telephone or email support and I've seen there are people from Cablecom on this mailing list, I would like to ask someone from cablecom to contact me about this issue at marco AT naefmarco dot ch for more information. Thank you. -------------------------- Best Regards Marco Näf AS201882

Cablecom DS-Lite breaks IPv4 path MTU?
by David Schweikert 02 Jul '15

02 Jul '15

Hi, I tried to report this issue to the Cablecom support, but I wasn't very successful... Recently, it looks like my home Cablecom connection was migrated to a DS-Lite setup. I get a public IPv6 address and a private IPv4 address. My IPv4 packets get encapsulated in IPv6, sent to a NATing gateway in the Cablecom network, and NATed there. At least, I have native IPv6 at home now, which is nice, but this is creating various problems for me. The worse one seems to be that path MTU is broken: dws@shuttle:~$ ping -s 1433 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 1433(1461) bytes of data. From 192.0.0.2 icmp_seq=1 Frag needed and DF set (mtu = 1474) From 192.0.0.2 icmp_seq=2 Frag needed and DF set (mtu = 1474) From 192.0.0.2 icmp_seq=3 Frag needed and DF set (mtu = 1474) So some Cablecom router is sending ICMP errors saying that I should fragment the packets to at most 1474 bytes, when in fact I am sending packets that are 1461 bytes long. As you can see above, ping doesn't work at all with path MTU discovery, because the discovered MTU is incorrect. If I manually reduce the size to 1460, it works, so this seems to be the real MTU: dws@shuttle:~$ ping -s 1432 8.8.8.8 PING 8.8.8.8 (8.8.8.8) 1432(1460) bytes of data. 1440 bytes from 8.8.8.8: icmp_seq=1 ttl=58 time=10.4 ms 1440 bytes from 8.8.8.8: icmp_seq=2 ttl=58 time=10.6 ms Do you agree with my analysis that this is a problem in Cablecom's network? Cheers David
