I were able to install the routerOS on it.

Don't Routerboards come with ROS preinstalled? Ours did.

You are just mentioning the eBGP specs (ISP with fallback). And for that the serverspecs are more than enough.

Depends on what version of ROS you are using:

routing-test is not available in the latest.

We will receive default bgp routes ...

I'll do some additional reading on route markers.

I feel like hijacking the thread. Sorry for that. The info is a bit fragmented. Seems I have to add 'extra' tables: ip policy-routing> table isp1 ip policy-routing table isp1> add dst-address=0.0.0.0/0 gateway=<ip-isp1> ip policy-routing> table isp2 ip policy-routing table isp2> add dst-address=0.0....

/ip route rule add disabled=no src-address=1.1.1.0/24 action=lookup table=isp1 add disabled=no src-address=1.1.1.0/24 action=lookup table=isp2 More questions keep popping up....I looked at the wiki but I can't find anything on how the identity of 'table=isp1' and 'table=isp2' is set up. In other wo...

Thanks, better start reading up on things....

Thanks for the quick replies. Is there an advantage for taking default routes over directly connected routes? I understand that the directly connected routes take more memory (at least a little) and it probably takes ROS a bit more time to update , but apart from that, what could be an advantage for...

yes, for full backup you should just prepend all announces to your backup link (with one rule) and of course you should _not_ announce default route to your upstream provider :D Right, got it :wink: Just another question... On the LAN side we only have directly connected networks (so no routing). S...

prepending is exactly what you need /routing filter add action=accept chain=isp2 disabled=no prefix=1.1.1.0/24 set-bgp-prepend=5 add action=accept chain=isp1 disabled=no prefix=2.2.2.0/24 set-bgp-prepend=5 So, in this case each prefix will have a prepend on different isp. To have everything go thro...

not sure about others, but our ISP receives only /24 ang greater networks. so you are likely can set preffered uplink per /24 subnet (or shorter mask) The smallest subnet you can count on to be advertised properly, is a /24. So, advertising an /21 to the less preferred uplink and a /24 to the prefe...

absolutely wrong. if you announce all your prefixes to all your uplinks, but with different prepend - you get full backup, and at the same time you can control, via which uplinks you will receive the traffic for those subnets So, you insert a default route into your network and propagate the static...

I have been reading about RB1000 dropping OSPF sessions and freezing in previous ROS versions, when taking full routes from a BGP peer. Current is 4.2 and I am wondering, if this problem still persists and if, in what way. How long does it take a RB1000 to take full routes from a peer and does the R...

routing-test is the same as regular routing in v4

so you should use v4 for the latest and greatest routing package

Thanks for the quick response!

The frequently reading of forum topics has made me confused :? For the RB1000 there are two versions available for download: RouterOS 3.30 (legacy) RouterOS 4.2 (stable) The RB1000 will be used for bgp (and no wifi, just wired isp). Everywhere I read, it says that for the latest fixes in routing iss...

Just curious: is this only when bgp combined with ospf ? Or does it also happen when bgp sessions are dropped and internally there is no ospf but just switched (the cpu load I mean)?

Thanks, that's clear!

Perhaps it is possible to backup the license file?

I read in some topics, that the license file may become corrupt or the cf card may die, which causes RouterOS to run without a valid license file. So, I am wondering, what does and does not keep functioning in RouterOS, without a valid license file. Does it stop functioning (completely or partially?...

Thanks for your reply. We would load the rb1000 with the max RAM to start with, since we can use 'simple' Kingston RAM or similar.

With the rb1000 we can finally start to prepare ipv6, so would be another step forward.

Hi, I have been reading this forum as preparation for the purchase of a rb1000. Currently we have a simple setup. Two BGP upstreams with full view (295k+ routes both), some ACL's for limiting inbound prefixes and blocking some ports, and internally just switching to a core switch, on which we route ...
