OPSF state is stuck in Exchange

Information

 
TitleOPSF state is stuck in Exchange
Symptoms
OSPF state is stuck in Exchange
Environment
NOS 7.2.0
VDX 
Cause
IP MTU and the Interface MTU were set to same size 1522 bytes. 
When IP MTU and the interface MTU are the same and the LSA update is greater than or equal to 1522 it leaves no space for the ethernet header and tears down the OSPF adjacency
Resolution
Enable jumbo frames on the interface to accommodate larger LSA updates.
