When configuring the OSPF section, I get the error about mismatch area:
*Aug 24 23:20:25.591: %OSPF-4-ERRRCV: Received invalid packet: mismatch area
ID,
from backbone area must be virtual-link but not found from 150.100.81.11,
FastEthernet0/1
The DSG shows to be getting these errors, too. However, the resolution was to
use ip ospf mtu-ignore. However, that didn't resolve my issue, even after
enabling on all devices.
My R8 Config-
R8#sh run int f0/1
Building configuration...
Current configuration : 117 bytes
!
interface FastEthernet0/1
ip address 150.100.81.8 255.255.255.0
ip ospf mtu-ignore
duplex auto
speed auto
end
I have configured mtu-ignore on all of the interfaces running OSPF on the
switches and the router interface.
My MTU is set at 1508 on all of the switches (and I don't know how to verify
the
routers MTU).
What am I missing? The ERRRCV errors are occuring every 10 seconds.
