Re: IPv6 recursive nexthops via iBGP

It's not possible to use Mikrotik in a real production-quality dual-stack service provider network without working BGP. I'd hate to see the CCR series, for example, be left out in the cold, if we have to wait for an entirely new generation of hardware to get ROS7. Not to spread FUD, but I don't have...

Re: Wireless Wire MTU, stability

You might create a temporary workaround by setting up an EoIP or VPLS tunnel over the wirless link. Both tunnel types support fragmentation and reassembly Thanks, sup5. In this case, I am using the wireless wire as trunks in a TRILL mesh, and TRILL adds headers already. So I need to be able to set ...

Re: Wireless Wire MTU, stability

Hi Tomas. I have started a ticket already. I hoped someone else might have seen this as well. In the context of any type of encapsulation, the actual configured MTU is somewhat misleading. The bridge will attempt to forward the packet, and the link crashes. There is no way to filter out the packet u...

Re: Wireless Wire MTU, stability

The plot thickens further. On both current and rc builds, Wireless Wire has an issue at any MTU over 1704. To replicate, set L2/L3 MTU on Wireless Wire eth1 and w60 interfaces to Nominal MTU. Send a packet through the bridge larger than Actual MTU, and the link will go down. Nominal MTU — Actual MTU...

Wireless Wire MTU, stability

I've been testing Wireless Wire with Ignitenet's Meshlinq (TRILL) switches in the lab. Version: current 6.42.6 Current 60Ghz max L2 MTU is 2290. Sending a decapsulated ICMP packet to the Wireless Wire nodes of > 2264 (including headers) causes a 60 Ghz link down event! In practice, this limit is eve...

Re: feature: show ospf and bgp on snmp

Derrick, I was thinking about extending the idea of the virtual interfaces to OSPF. Doing something like monitoring adjacency count, and downing the bridge using a timer (for detecting flapping). Have you tried this?

Re: [MPLS-TE] Balancing 2+ different bandwidth links [SOLVED]

I've been working on a pseudo-manual method using MPLS-TE, BGP communities, and link coloring to "manually" make more preferred paths for traffic-of-interest, overriding OSPF costs.

Does this interest you?

Re: IPv6 recursive nexthops via iBGP

ZeroByte, thanks for the detailed comments. After further testing, I have reached the same conclusions you have. I would rather not tunnel — although I did briefly contemplate a full-mesh MPLS/VPLS for directly peering each IPv6 router. (Traffic queue management would be just one problem with that d...

Re: IPv6 recursive nexthops via iBGP

Hi 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) hk Let me recap, and please correct me if I'm wrong. 1. Under no circumstances...

Re: Monitor logs, send email alert / run script

I think the problem is that "/log find" is broken.

/log find topics~"info"
/log find where topics~"info"

Both return no entries in 6.37.3 or 6.38.1

BGP stuck open sent/tunneling

I run a BGP session over an L2TP tunnel. Normally this works fine. Occasionally though, one end of the peer (the L2TP client end) will end up with the tunnel established, but the BGP peer stuck in 'open sent'. When this happens, the only recourse is to bounce the BGP peer (disable/enable.) This peer...

Re: Google Cloud IPsec VPN to Mikrotik IPsec VPN problem.

You need to get lower-level technical specs for the VPN in order to be able to setup your router. There probably exists a document that lists these specs. These are available; look for the compatibility settings for Google Cloud VPN + AWS. I got as far as phase 2, and SAs installed, but then ran in...

Re: CCR ethernet port failures?

I guess the appropriate question is when should I RMA them? Frustrating if I can't trust them out of the box. I'm a long way from anywhere and from what I hear RMA is often not worth it. Advice?

Ubiquiti has admitted that they are not passing these packets. They'll look into allowing them. (The RFC implies that they should be passed, but does not make it explicit.)
