Re: Redistribute static routes to OSPF

So for example to allow only routes in 192.168.0.0/16 to be distributed and the rest discarded: /routing filter add chain=ospf-out prefix=192.168.0.0/16 action=accept add chain=ospf-out action=discard Suddenly realized I was a bit misleading here. That discard rule will only match the exact route o...

Re: Redistribute static routes to OSPF

Yes you can use the filters to discard routes. The OSPF instances have by default the filter chain "ospf-out" set as the out filter. So for example to allow only routes in 192.168.0.0/16 to be distributed and the rest discarded: /routing filter add chain=ospf-out prefix=192.168.0.0/16 action=accept ...

Re: Default route from OSPF not getting installed if static route exists

If both routers have set to redistribute default route and both of them have static or other protocol default route already in routing table, then OSPF default route will not be installed. Unfortunately that is the consequence of current OSPF loop detection implementation. Ok understood.. I don't l...

Re: Default route from OSPF not getting installed if static route exists

If there is already static default route and you want OSPF to install default route then remove "distribute-default" in ospf instance for that router. But in my case both routers should advertise the default route to each other (if they have one installed). If the ISP link on R1 fails, it will no l...

Default route from OSPF not getting installed if static route exists

I have a problem with OSPF default route not getting installed if another default route exists. There are two routers, R1 and R2, both on 6.37.1 - Both routers have an uplink to one ISP and a default route to them. - The distance for the static default route in R1 is 1, this is a 100Mbps link - The ...

Re: 6rd support?

Can we get some kind of update on 6rd plans?

If it's not in the roadmap for the next year, I will have to start buying something else.

I don't like it. It's a kludge. But it's the reality of IPv6 access for a major part of the world.

Re: 6rd support?

+1 for 6rd support from Finland as well, it seems like all the local ISPs are rolling out 6rd because the regulator went and said that it's an ok way to roll out ipv6 to end users. Doh.

Yes the regulators recommends DHCPv6-PD etc but what we get is 6rd.

IPv6 RA trouble when upgrade 4.17 -> 5.9

I bumped one of our routers (RB1100) to 5.9 from 4.17 yesterday and now we're having a bit of trouble with IPv6 router advertisements. It seems the devices are getting an RA and the prefix is configured ok, everyone has a public IPv6 address. But the default (::/0) route doesn't get installed in the...

Dividing up bandwidth equally between 4 houses

I'm trying to set up an equal division of bandwidth for a 10/10 Mbps uplink that will be serving 4 houses. So I want everyone to receive at least their 2.5/2.5 but of course be able to utilize the idle bandwidth if everyone isn't burning up their share and I need a bit of advice... Never having set ...

Re: RouterOS 5.0 is out!

This is correct, that in v5.0 you will see higher CPU usages with BGP. It is due to more frequent nexthop calculations which is made to address several problems where nexthops were not updated correctly. CPU usage depends on how frequently peer receives updates (more frequent updates will cause hig...

Re: How To Limit ICMP Packets Count !?

I think you need to add a drop rule for the icmp after that one. Your current rule is accepting ICMPs (5 per 5 seconds average), but there is no rule to drop the rest.

Re: RouterOS 5.0 is out!

So is the BGP memory leak fixed? I'm still running 4.13 that came installed on our RB1100, but it's leaking memory running BGP. We're taking full routes from one peer and just default route from another. So about 350k prefixes. Memory use seems to creep up... And now I'm wondering should I just go t...

Works like a charm, thanks again. I set this up through Winbox and I'm just not careful enough it seems. Have to force myself to learn the CLI syntax.
