Unless you set both sides to ignore it like you can do with some other vendor equipment.

Hi, for what I know, MTU is part of the OSPF negotiation, so if they are not the same on both sides, adjacency will not come up.

You should always match mtu if you want to avoid having problems down the line, specially with protocols such as ospf and bgp On 2013-07-26 7:33 AM, OBrien, Will wrote: You have to match them appropriately.

[j-nsp] OSPF between Juniper and systems
In a broadcast interface (GE) I’ve to run OSPF between my MX and some systems running OSPF. What about L2 and L3 MTU ? Can I fix greater MTU on MX and the OSPF adj will come up or not ?
