Re: CCR DDOS CPU Load

Seeing basically the same issue - CCR cannot handle any tcp+syn type DDoS at all and falls over. 6.18 (our tested most stable version, no plans to upgrade for now since otherwise stable.) But is a big disappointment. Like CCR otherwise, but may be forced back to ASR or MX gear due to these issues. P...

Re: CCR1072 Availability

I'm waiting to purchase a large quantity of CCR1072-1G-8S+ .. any chance we'll see them before year end?

Re: v6.19 SNMP problem?

I upgraded a CCR1016-12S-1S+ to 6.19 from 6.18 and now snmp is broken.

Were you able to find any resolution?

Re: multihoming and source address of outgoing icmp messages

What configuration exactly on cisco do you use? As far as I can find you still need to use NAT on Cisco to change ICMP replies. http://networklessons.com/network-services/cisco-ios-nat-stick-configuration-example/ for other protocols, BGP, NTP ... loopback source is specified explicitly in configur...

Re: multihoming and source address of outgoing icmp messages

have not seen a solution for this. Pretty annoying. I believe janisk answered this... Mark the packets and return via the same interface. Other then that, I think you would have rewrite the reply but NAT would only address IPv4 traffic... Maybe there isn't another answer for this because there isn'...

Is this the way it is meant to be ? Is there really no way for MT to test that themselves in the lab (no...

Re: 6.9 released!

We are seeing crashes over multiple devices with CCR1036-12G-4S i'm afraid - appears to be related to VRRP. Kernel error and reboot, then both routers attempt to act as master but are unable to pass traffic. Manually removing/readding vrrp or disabling VRRP allows traffic again, however we've then o...

Re: CCR 1036 BGP fail to load full table

We have no issue with 20+ CCR and many full tables, including some peers that are quagga/vyatta based. Full table loads in under 20 seconds.

I'd point to an issue with your peer or some sort of link problem.

Re: multihoming and source address of outgoing icmp messages

Did you ever find a solution to this? Running into the same exact issue - multiple CCR's, 5+ upstreams with full tables. Inbound traceroute via upstream A will show the interface IP of upstream B/C/D randomly which is confusing. It seems like source ip of the icmp packet hitting upstream A is set to...

Re: CCR 6.0rc7 105 (No buffer space available) loss of ipv

Do you have netflow enabled? Have been working back and forth with mikrotik support on this - it boils down to netflow. They sent me a patched RC14 version but that stops all bgp from working. AS of now I've run ~5 days (the longest) w/o netflow and haven't seen a crash. Will get back to testing the...

Unfortunately this is still happening, even in the latest build: version: 6.0rc12 build-time: Mar/26/2013 17:18:12 This happens on numerous CCR1016-12G that we have. It does not happen (thankfully) on CCR1036-12G-4S as of yet. Unfortunately I mist surmise that Mikrotik isn't ready for prime time yet...

Re: CCR 6.0rc7 105 (No buffer space available) loss of ipv

We fixed this problem in one of the latest rc12 builds. Contact support to get newer build.
Unfortunately this appears to still happen for me with the latest build:

Re: CCR 6.0rc7 105 (No buffer space available) loss of ipv

I've been back and forth with Mikrotik support on this for weeks, open case - so far no solution. Have tried beta rc12 and it happens there as well.

I'm suspecting a hardware related issue as this only happens on one unit and not others with identical configuration.

Re: ccr dot1q access vlan

@sx10 thanks much - I don't have access to the other end config (it's a carrier) but I would assume standard cisco/juniper dot1q trunk.

I've tested with a bridge and still no luck, I'm going to assume I've been provided the wrong vlan-ids or something else is amiss!
