Is it possible to use one of our assigned Public IPs on external router connected to another ISP?

We have a block of addresses that has been assigned to us by Afrinic (RIR for this region) We are announcing this IP block via an eBGP session with Vultr (making use of this service: https://www.vultr.com/features/bgp/) Now, could we route, direct or point one of our public ip addresses to a router ...

Re: DHCP lease unsuccessful after upgrade to 6.48 [SOLVED]

CRS3xx offloads bridge VLAN settings to underlying hardware, while the rest of devices implement everything in software. It is possible that pure software implementation is more forgiving than hardware implementation. You have plenty of VLANs configured in proper bridge-vlan manner. So why don't yo...

Re: DHCP lease unsuccessful after upgrade to 5.48 [SOLVED]

So, I just tested the exact config on a 3011 and a hap lite, and it works as expected. But why does the exact same config on the CRS not work?
I cannot connect to the CRS even via RoMON (romon is enabled on both the CCR and CRS)

Re: DHCP lease unsuccessful after upgrade to 5.48 [SOLVED]

Basic idea is: when bridge vlan-filtering is enabled, then VLAN interfaces have to be configured off the bridge, not off member interfaces. But in this config, the vlan should be on the member interface, right? Because I just did a lab now, added the vlan interface to the bridge and it did not work...

Re: DHCP lease unsuccessful after upgrade to 5.48 [SOLVED]

Basic idea is: when bridge vlan-filtering is enabled, then VLAN interfaces have to be configured off the bridge, not off member interfaces. Anyway, in this case bridge VLAN filtering doesn't apply to traffic via that VLAN interface at all. Could you give me a deeper explanation why you say " A...

Re: DHCP lease unsuccessful after upgrade to 5.48 [SOLVED]

Basic idea is: when bridge vlan-filtering is enabled, then VLAN interfaces have to be configured off the bridge, not off member interfaces. If VLAN interface is defined off a slave interface, then behaviour is slightly undefined (and might change as well between ROS versions). It may have worked &q...

Re: DHCP lease unsuccessful after upgrade to 5.48 [SOLVED]

I have configured my VLANs in a different way, I configured all VLANs on the bridge instead of on the interface: https://forum.mikrotik.com/viewtopic.php?t=143620 Thank you for the reply. For VLAN config I have followed this: https://wiki.mikrotik.com/wiki/Manual:Interface/Bridge#Bridge_VLAN_Filter...

DHCP lease unsuccessful after upgrade to 6.48 [SOLVED]

The DHCP server was happily giving the lease to the switch. I did not change any configuration, only upgraded the CRS from 6.47.7 to 6.48 and the DHCP server lease cannot be given successfully to the switch any longer. To confirm, everything was working fine, simple upgrading the switch caused this ...

Re: Network architecture recommendations

I would go for the second topology (with red dotted flows) so use indeed separate interfaces towards ISP and clients. Is this equipment located close to each other ? Or does "ether7" run across some provider L2-link to some remote location where the EdgeSwitch is located ? The equipment i...

Re: Network architecture recommendations

Having designed and built hundreds of WISPs, i've got a few things to share with you that may be helpful. Thank you very much for this detailed information. Actually I am using your presentation: BGP as an IGP for Carrier/Enterprise Networks - MUM - MikroTik as a template for my network. By the way...

Re: Network architecture recommendations

With router on a stick concept every packet passes the switch-router connection twice, once in each direction. In both directions there's mix of ISP-bound packets and clients-bound packets. If uplink/downlink throughputs were symmetrical, this cocept would effectively halve the link capacity. So if...

Network architecture recommendations

I am implementing a WISP network.Usually I would use separate physical ports for internet breakout/wireless backhaul. But I have changed this and now only using VLANs via a managed switch. Is this a better way? Are there any potential disadvantages of this design? I would like to hear what sort of a...
