crs125-24g strange problem...

RouterOS General
1

hi, This is my setup :

1 x rb960pgs running ospf, vlan, mpls, vpls and at peak hour ± 90 mbps max
this router is connected to a crs125-24g switch. Then we add vlan into that switch for ospf legs and APs.

If i ping from the rb960 to the switch i get ±3% of lost. (so my ospf goes crazy and break)

I decided to change the crs125 to a crs112-8g (because i had this one in my office)
Everything was fine while 3 weeks. Except the cpu that was crazy at 100% when 50mbps passing through it.
I replaced the crs112 to a new crs125-24g switch, then I get the same problem that i had with my first crs125 switch.

I run 6.42.0 in my rb960pgs
I run 6.41.3 in my crs125-24g

no fcs error,
1gbps nego
no link down


ANY IDEA?

Your configuration is wrong.

i guess, but the same config work in my crs112, but not in my crs125

Unless you provide the config., we will never know, will we?

It’s pointless asking questions like this without providing any details. When will people learn?
