Hi all,
I read examples for MPLS but there are still some things are not clear, can anyone help
Comparing to cisco routers
what meen L2MTU on interface ? max mtu that interface can have?
because, if on cisco router if set mpls mtu to 1522 , do i need to modify ip mtu on interface on mikrotik router or just mpls mtu
can anyone share how he configure ip and mpls mtu with cisco and mikrotik
because i what to use mikrotik in my network.
Here you can find expanation of differences between L2mtu and mtu. Also in this article you will find what is mpls mtu with examples.

Hi
Thank you but i have little problem.
On Cisco ASR1002 , i have few subinterface gi 0/0/0.200 , gi 0/0/0.201, gi 0/0/0.202 etc
on gi 0/0/0 i set mtu to 1522 , and so all subinterface get mtu to 1522
asr is connected on cisco switch 3550 whit mtu 1546 on FastEthernet , and on that switch mikrotik routers
Problem is when subinterface have mtu 1522 and mikrotik 1500 ospf dont work
so i set command ip mtu 1500 on subinteface but dont work
on mikrotik log i get too large mtu , mine=1500 recived=1522
Anyone can help?
MTU on both sides must be the same otherwise OSPF is not going to work. Either you set MTU to 1500 on both sides or 1522 on both sides.
Yes i know that
Why mikrotik router when i set command on cisco subinterface “ip mtu 1500” , in log mikrotik says mine=1500 , reciving mtu 1522
And to add i Just tested , i set mtu on cisco 1522 and mikrotik 1522 and when add command on cisco subinterface “ip mtu 1500”
mikrotik in log than say mine=1522 reciving=1500
And isnt mpls mtu = ip mtu + number mpls tags * 4 ??
