Re: RouterOS equiv. of Cisco's "ip ospf mtu-ignore"?

You shouldn't have mismatching MTU's on links anyways, so you'd best just fix the MTU and then as an added bonus, you'll avoid all the ugly issues that arrise when you have an MTU mismatch.

You need to use encapsulation mpls.

Also, be sure that basic MPLS works first, and be sure to have LDP neighborship between your routers.

I think you're looking at the wrong issue here. Whether you run OSPF or EIGRP has nothing to do with graphing.
Graphing comes through SNMP. Check if you're graphing the right OIDs, as the MIBs may be different between cisco and MikroTik.

I think I've found the problem.

Our PoE is the standard one, so it's not supplying enough voltage for the board to pow...

Re: rb493 managed switch with vlan support?

If I bridged an untagged interface and a vlan interface, the arp requests of the data traffic coming from the tagged...

Re: RouterOS 3.25 BGP

I was forced to upgrade my bgp routers to 3.25 due to some bug with a newer version of Cisco routers, that was triggered after one of my upstreams upgraded their routers. So far, it seems stable. I haven't stress-tested it, but my routers are stable, and that's what counts for me :)

No no, 10.10.10.1 is still in another subnet. Since it's a point-to-point network, there is no broadcast. The network 10.10.10.2/31 consists of 10.10.10.2-10.10.10.3. Please read the RFC if you've never dealt with /31's before... It's an easy read.
