We tried esx 6.7 but never could get actual throughput over 7Gb. Loopback testing was 61Gb. We are testing debian 10 with frrouting right now and are getting 38Gb throughput and around 25% load across all 20 cores. No core is loaded more than 30%. We much prefer the mikrotik interface but as of righ...

We are working on getting our new CHR's tuned and configured. We have used the bandwidth test to the internal loopback interface with good success. We are getting different results on testing between the 2 different CHRs. Is this to be expected? We have tried disabling VMQ, offloading, upping the qu...

Could we get a linux version of winbox?

Wolfraider

We have not had any trouble in the last several releases until 6.45. We always watch the forum to see any issues that other people have before updating. I think the issue is coming from that they tried to push the 6.45.1 release out quickly cause of the cve and then tried to push this one out quickl...

Wolfraider

I completely missed that. Thanks

Wolfraider

Not as easy when you have a few hundred vlans. Not bad to script but would be nice to have a simple checkbox to automatically have all interfaces as passive and then add the ones you want.

Wolfraider

I wish there was a simple way to mark all instances as passive except the ones we add manually.

Wolfraider

That would be my vote also but would double the cost and doesn't have an outdoor case.

Dual Polarity maybe?

Wolfraider

I haven't tested it yet but what about the PowerBox Pro for small tower sites and MPLS/BGP/OSPF? Or maybe the RB450Gx4 with a custom case.

Wolfraider

Same issue just happened to us. RB4011 running OSPF, BGP and MPLS. Timeout while waiting for program filled the logs, random numbers. Also error dhcp1: failed to give out IP address: unknown pool mixed in. Reboot resolved the issue. BGP is offering default routes only, OSPF is providing 202 routes. ...

We tried that and no change in ccq. We changed from nv2 to nstream and we are currently running at 99% ccq. Signal level dropped to around 57. This link is rocking now. Currently ordering more netmetals to replace more links.

Wolfraider

Unfortunatly Mikrotik does not have OIDs for BGP. We use LibreNMS for monitoring and was able to use the nagios plugins and the Mikrotik BGP plugin from here https://github.com/ohitz/mikrotik-tools Works pretty well.

Wolfraider

Ok thanks, we was already thinking about changing that. We will test Sunday.

Wolfraider

We actually just replaced our AirfiberX with the Mikrotiks. Getting double the bandwidth currently. We have heard that version 2 is alot better than version 1 but after the issues with the link we are reluctant to spend that kind of money if the Mikrotiks perform well. Signal on the Airfiber was -73...

Did not see much channel usage for this frequency in the snooper, freq usage or scan. What option is Greenfield. I am currently researching it.

Wolfraider

Nope, all over land. Running the link calculator, looks like the closest object to the Fresnel zone is 54ft away.

We have setup a 34km link, signals are bouncing around between -65 and -48dBm. CCQ is running between 40 and 64%. We dont see much in the way of interference. Anyone have any ideas on how to tune this link? We spent around a couple of hours finely tuning the alignment. Both radios are a NetMetal 5SH...

Wolfraider

We are not running eBGP as of yet but I will post numbers as soon as we get this implemented.

Your getting better performance with Hyper-V? I have heard others talk about better performance with ESXi. We could go either way. I'll post back numbers.

Wolfraider

We will be assigning a couple of our ESX licenses for this. We like the idea of running 2 physical servers instead of 1 just in case of hardware failure. We are currently running a couple CCR1072's but we have not brought up our second 10Gb trunk up yet or received full routes from either carrier.

Wolfraider

We are working on new replacement routers for our core network. We will have 2 independent 10Gb peers and full tables from each. What would be a good low cost server to run CHR on? I will admit that I have not been in the server field for several years and I am almost lost on all the new options. We...

Wolfraider

Had another outage last night that spiked the CPUs on the CCR1072 core to 100%. We disabled BFD on all OSPF and BGP links. Hoping that doesn't happen again. The one test link stayed connected but could not route since the CPUs was maxed.

Wolfraider

Core - CCR1072
Client Sites -
CCR1009
RB4011
RB2011

Wolfraider

Setup NBMA on our link. Set the core as priority 1 and the site as priority 0. Also disabled BFD. Lets see how that works.

Wolfraider

Thanks, I will test that.

Wolfraider

Check with your isp. Ours will allow us to advertise their ip space on our asn.

Wolfraider

I have enabled OSPF debug, waiting for it to go down again.

Wolfraider

We have a central core and several border routers that randomly go offline. We have noticed that all OSPF connections report down at the same time. We have 1 big MPLS circuit connecting everything together but we created a VLAN per site (currently 28 sites but planning on adding another 20) and setu...

Wolfraider

Thanks for that link. That is something we are watching. We will have rough 20 PPPoE connections max per edge router. With over 100 edge routers, this is why we dont want to dedicate a subnet per site. Instead we want to use the /32. It would be nice if the Mikrotiks had PPPoE Relay like the Ubiquit...

I am trying to create a script that when a client connects through PPPoE, their remote address is added to BGP networks. I created a ppp profile and added the following scripts to it but they never seem to get called. On Up /routing bgp network add network=$remote-address/32 synchronize=no On Down r...

How well would the RB450Gx4 perform with MPLS/OSPF/iBPG? We are looking at using these for our edge devices. We are setting up a full MPLS backbone using OSPF internally and then using iBGP to route public addresses. The only other thing it might be doing is NAT. Expected throughput will be up to 20...

Wolfraider

After help from /u/Dankleton, we changed the MPLS MTU to 2020, l2mtu to 2024 and IP MTU to 2000. This helped but we have discovered that the hardware in the CRS112 is not up to the task of running MPLS at all. The CPU will peg 100% when trying to push more than 100Mb. We went with these since we nee...

Wolfraider

We also tested this with a VPLS tunnel instead of the EoIP tunnel with worse speed results.

Wolfraider

Could we get a sanity check on our config? We have our Core router CCR1072 with a 10Gb uplink to the internet (sfp-sfpplus1 vlan 803) . We have a 1GB fiber connection from the Core router (sfp-sfpplus3 vlan 3000) to SW1 CRS112 (ether1 vlan 3000). We then have a wireless Ubiquiti rocket AC lite link ...

Wolfraider

Check to see if you have the api enabled. Firewall if you need it. Disable if you don't. That is how they are accessing the device.

Wolfraider

This may be my tired brain thinking way too hard and not seeing things clearly. I am wondering if I could setup a VPLS tunnel between the 2 core routers and run VRRP between them. Maybe a really bad idea, lol cant think. Headed to bed.

Wolfraider

Sorry about that. I meant to put in more detail but had a quick service call come up. We want all our traffic to go out upstream 1 with the public IP addresses. If we lose upstream 1 or any back hauls running to it we want the tunnel to fail over to upstream 2 on the other side of the network and us...

Wolfraider

We are working on a new design for our wireless network. We are working on converting our backhauls over to MPLS/OSPF and a meshed design. This works great for failover internally. The biggest hurdle we have is the design of the failover of our upstream providers. We have 2 upstream links, one on ea...

Wolfraider

We got hit with that too on a test router. I took a backup of it before I wiped and updated the firmware. The funny part was we had firmware 6.41.3 on ours and that was only 2 months behind. /ip firewall filter add action=tarpit chain=input comment="Add you ip addess to allow-ip in Address Lists." d...

Wolfraider

I set the source interface to the loopback and that fixed the peering issue. Setting syncronize=no fixed the router advertisement. I went through the second presentation and will watch the first one tomorrow. Thanks for the help.

I am working on a new design for our WISP. We currently have around 800 customers and around 50 towers. We are getting ready to order 2 Mikrotik CCR1072's for our core routers and upgrade from a bridged network to MPLS. Our needs are as follows Clients get a static NATed IPv4 address or static Publi...

I would vote to have a simple router to use at a residents house that had an ATA built-in. This way we don't have multiple devices to support and manage.

The above rule did not work but I think we was on the right track. We ended up dedicating a public IP address per building and everything started working. Thanks for the help.
