[c-nsp] MTU Mismatch

[Mohammad Khalil]

hi all 

i have Cisco 3750 connected to 6523 switch
on the 3750:
interface GigabitEthernet1/1/2
 no switchport
 ip address 10.20.3.18 255.255.255.252
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip ospf network point-to-point
 speed nonegotiate
end
sh int g1/1/2 | inc MTU
  MTU 1512 bytes, BW 1000000 Kbit, DLY 10 usec, 

on the 6523:
interface GigabitEthernet1/27
 ip address 10.20.3.17 255.255.255.252
 ip ospf network point-to-point
 load-interval 30
 speed nonegotiate
 no mop enabled
end

sh int g1/27 | inc MTU
  MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec

The problem is that the OSPF is running and functioning well , how does the OSPF neighbor relation is up and there is an MTU mismatch ?
