Hi
upgraded CCR1072 - works fine.
but: snmp, warning arises with "timeout while waiting for program 79"
which is not ideal.

*bridge - added per-port based "tag-stacking" feature trying to wrap my head around this vs the (previous) QinQ support by using ethertype=0x88a8 if I'm not mistaken this is now the more common support for QinQ using 0x8100 frames packing another 0x8100 frame into it (aka stacking). my question here...

hknet

Do I read this correctly as _no_ routerboard-firmware upgrade is usually required coming from 6.43rc or 6.42.7?

Well you guys did want a security blog and more awareness. Now you complain that the issues are not serious enough :D We will try to find a balance. I hope you understand that when you post a new version AND update the bugfix version at the same time, mentioning 4 security issues that have no descr...

Hi this might be a tricky one, any food for thought would be appreciated (and consulting offers are welcome too if you know what you're doing). The scenario goes like this: there is one QinQ port that is shared between several users of this shared infrastructure. the s-tags are generated per infrast...

Hi
feeling a bit dumb, but has anyone ever managed to use a microSD in the ccr1072?

we seem to be unable to solve this riddle.

and while we are at it any tested smartcards for the smart card slot?

Hi on a cisco router we do something like this: route-map RK permit 50 match ip address RK set ip next-hop 192.168.1.1 this route-map is then bound to an interface that is the incoming gateway for packets like interface vl10 ip policy route-map RK in other words if the source IP matches the RK addre...

after seeing issues with CRS317 an 1G SFPs (not 10G) not linking with latest 6.43rc44 (getting auto negotiation as incomplete) we tested a downgrade to the current 6.42.6 and see auto negotiation failed. copper 1G SFPs do not see any advertised 10/100/1000M link-speeds while the other end gets auton...

hknet

model: CRS317-1G-16S+
release: v6.43rc44

we use some ports with non-10G SFPs (ie 1G-SX and 1G-TX modules with fiber and copper).

those modules get auto negotiation 'incomplete', while claiming the link is ok but no working datatransmission can be established.

@RoadkillX you do not test your setup on the mentioned HW therefore it's invalid and not what anybody was asking for. @TestCRS thx for the ethertype reminder from RoadkillX I found the relatively simple case to do: set the vlan added to the bridge with "use service tag" and you should be fine. -> se...

hknet

QinQ requires intervlan. it's a vlan interface inside another vlan interface so revisit the docs ;-), to be more clear QinQ requires 2 vlan interfaces which can't be hw-offloaded because they are L3. you might brush up your knowledge, you are misinformed and did not read the first post to understan...

hknet

it should do 10Gb within the same vlan but not intervlan

the original poster was never talking about inter-vlan-anything maybe you should revisit the original problem-report.

hknet

This is not a bug, its clearly misconfiguration respectfully disagree - the CRS and the new bridge-hardware-accelleration config to use it as a switch and get hardware-forwarding is what the original poster tried to achieve imho (and I see no flaw in the config); you are referencing the implementat...

hknet

I cant se your C tag in your setup. A ctag is a vlan to a vlan interface... You need to paste your complete setup with vlan tagged to another vlan interface. well, I guess there is no specific c-tag configured (as the CRS317 wouldn't support qinq in hardware anyway), therefore the claimed s-tag (vl...

hknet

As other people wonder - Are we/Have we gotten hardware support for QinQ?

Doesn't look like it, though the Marvell 98DX8216 is a metro chipset (marvell's words) which would suggest 802.1ad should be available at the HW level.
But my guess is we won't see this with this HW.

EoIP Ethernet Frame issue is still there (introduced in 6.42 breaking fragmenting big frames somehow broken) verified on RB2011 and sent supout to MT-support.

it seems we lost packet fragmentation for EoIPs connecting bridges between two MTs we no longer can transport big pppoe-frames there; was working with 6.41.4

Web, winbox, ssh etc access to the router works only in main routing table. It isn't totally correct. Because if you've got access to the Internet from main route table, mikrotik gets inbound request on VRF interface and sends reply via Internet interface in main route table. Is it possible to chan...

well after fixing the threshold issue on the ciscos-side we see a MLPPP issue on the mikrotk end... it can be reproduced quite simply: if we max out all our mlppp-pppoe-links (using bw-test) then we see dropped links which are established immediately, but the linkd-down causes loss in bandwidth and ...

Hi we test MLPP on ROS 6.41.4 using two ethernet-interfaces and a PPPoE interface that uses those interfaces and connect successfully. We tested using 2 and 4 (i.e. using eth1 twice and eth2 twice) links. the interesting phenomenon is that we always loose the second pppoe-session (pppoe1.2) no matte...

We see a development (and others too) port scanning for winbox 8291 is dropping while port 2000 (bandwidth-test-service) is going strong.
Also telnet ist still highly active with those hijacked mikrotiks.

Just to make it clear: only devices running a not up-to-date RouterOS version are affected, whose HTTP port (TCP/80) are open and provides the login facility and management GUI, right?

Well "Nexthop self" in an bgp environment is an abomination. It should not be needed - agreed, but real world teaches us: One looses an external interface and therefore the nexthop is removed from the IGP. In a small network this converges fast and causes virtually no service disruption. Think about...

hknet

Hi. RR's need not to be in data path (most often aren't) so please consider your own setup before fiddeling with above statement. ahem, the nexthop delivered by RRs was not implying the nexthop in fact is the RR, in fact the nexthop is usually the IP set by "next-hop self" (or similar) by BGP-route...

Hi saw this thread reactivated :) The only workaround we have seen so far for iBGP IPv6 routes to get active is to add a static ipv6 route for the loopback IP for the next-hop delivered through the route-reflectors. (again tested with RouterOS 6.40.2) If there is any workaround, I'd be glad to hear ...

Hi tunnels sound like a plan, you then could talk ospf on those tunnels and between routers A+B and C+D. In order to get your upstream in the datacenter to make connectivity redundant you would need to speak some routing protocol there too, usually BGP might be an option, alternate you can form VRRP...

Posting questions and reading answers in forums is already doing some reading. :) Where did you get the two ISP idea?

The mentioned 154 Mbps by your carrier make the access technology smell like ATM.
