Re: Slow speeds with VLANs on CRS125

If you need Gigabit routed throughput, CRS is the wrong device because it won't ever process TCP streams fast enough to get clean throughput for real applications (which is different than maxing out a bandwidth test). Consider adding a CCR1009 or RB3011 to handle routing and then connect the CRS125 ...

GRE is good as well but it really depends on whether or not you need Layer 2 or Layer 3 in your design. EoIP is popular because it is a very inexpensive way to extend a Layer 2 network and get decent speeds without the complexity of MPLS.

Re: bgp doesn't reconnect?

6.31 is not considered the most stable as it has lots of new features. We do an enormous amount of BGP consulting with MikroTik and have found 6.30.4 to be very stable peering to multiple providers. If you have the same issue with your routers after moving to 6.30.4 on two different CCRs to two comp...

Re: BGP + OSPF (RR instead of "full mesh").

The link below is a great place to start when trying to figure out route reflectors. http://wiki.nil.com/BGP_route_reflectors The biggest problem you are probably running into is using static routes for your loopbacks and transit subnets when OSPF is always the preferred method within a MikroTik bas...

Re: bgp doesn't reconnect?

Try 6.30.4 bugfix on both. We have found it to be very stable on BGP.

Re: version confused

Bugfix is considered to be the most stable of all versions right now. Current bugfix version is 6.30.4.

Re: 6.32.2 released

There are no new features, but it is not replacing the 6.30.4 as the "stable" one yet. When it will be polished enough, it might replace it, or maybe the next one Glad to hear that....we have been recommending 6.30.4 to our clients for pretty much all of the production networks we are involved with...

Re: eoip tunnels

You can set up as many EoIP tunnel pairs as you want if you keep incrementing the tunnel id field on each pair of EoIP tunnels. You have to build a new server side EoIP interface for every client though. If you want Layer 2 multipoint then you need VPLS.

This is the equivalent of longer prefixes:

This is for an exact prefix length:

Re: BGP Advertisements

Depends on what your upstream is accepting.

This will tell you what you are sending

And then you can go to a looking glass to see what is actually making it onto the net

Re: Real CCR1072 experience?

If you put a 2 ms RTT (not unreasonable with a test port on each side of the DUT) into the calculator it gives a max throughput of ~ 58 Gbps at 1500/1460 bytes. Suggests that you don't need to tweak this at least. Might need to up the window size of the tester though (assuming it actually runs a TC...

Re: BGP Problem with route reflector

Three questions:

1) If you are advertising the next hop in OSPF, then turn off next hop self on all peerings to see if that resolves it.

2) Please post the peering config for db0sys , it doesn't seem to be listed in the config.

3) Can you post the cisco config as a comparison?

Take a look at example one in the link below....the config on ether2 is probably what you're looking for. Bridging is not the best way to use VLANs in a CRS.
