I tried 6.49beta11 and BGP was flapping like mad on it, certainly don't run that version in production.

Are you using 1Gs - optics or rj45?

I dont have lockups in ospf/bgp. We have seen interface down/ups and resets. Hmm, maybe that is what I have been experiencing too. I haven't noticed any syslogs for the interface going up/down though. The syslogs that I have noticed are "OSFPv2 neighbor x.x.x.x; state change from Full to Down....

I have just re-designed my network to be Static Routes/BGP instead of OSPF/BGP. I hope removing OSPF from our design has resolved these issues.

Got a reboot on one now on 6.49beta11.

…and now same here with the 6.49beta11 "SFP at 1G is not stable" bug.

For us the 1Gs report 10G. Same for you?

mhugo

What version of RouterOS are you running? I might swap to that.

This bug claims to be fixed in 6.47.8 and then some more in 6.48. Ive had reboots on 6.48 but not on 6.47.8 so running 6.47.9 now.

These is also a version 6.49rc11 that fixes some more, but it broke sfp support.

mhugo

Same here, 6..48 and a lot of reboots.

We had 2 reboots on 6.47.8 14 days ago in same day for 2 routers. After that nothing. We don't run 6.48.

Are you making tickets? We need to keep the pressure on mikrotik so they realize it's an ongoing issue.

/M

mhugo

Hi,

One thing I notice is that MT like with the new CCR2xxx has 2 faster ports, but I would say 4 would be required.

2 ports only makes it possible to build rings, but with 4 or more meshing is possible. For me 4 would be enough normally.

/Mikael

mhugo

Hi,

Got confirmation that the fixes are in 6.47.8 so no additional fixes in 6.48.

Mikrotik is under the impression this is fixed so please keep reporting if it crashes for you.

We had 2 reboots with 6.47.8, but it's much better and some routers has been up for 38 days now.

All fs.com optics in ours.

What we miss are more than 2 highspeed interfaces on the CCR2004s and upcoming 2016.

Ours have not yet rebooted - all have full BGP - 25 days since last.

Hi,

Are any of you experiencing reboots still? We actually havent had any on 6.47.8 yet and the interfaces going down could have been from an RJ45 sfp plug which does makes me wonder about power in the sfp cages on the 2004, but it wasent even connected to anything so was easy to remove.
