Problem - Mismatched Area ID
%OSPF-4-ERRRCV: Received invalid packet: mismatch area
ID, from backbone area
must be virtual-link but not found from 170.170.3.3,
Ethernet0The router generating this message received
an invalid OSPF packet on Ethernet 0 from neighbor
170.170.3.3. The packet is invalid because its area ID
is area 0 (the backbone area). This implies that the
receiving router's Ethernet 0 interface is not in area
0. Note that the neighboring router, which has its
interface in area 0, won't display this message in its
console logs. Only the router whose interface is in an
area other than area 0 generates the error message.

To avoid these messages, make sure that both sides
have the same area ID by checking the network
statement under OSPF in the router configuration. For
example, if the link 10.10.10.0/24 between two routers
should be in area 1, make sure the network statement
on both routers includes this particular link in area
1. The network command on both routers would look like
this:
router ospf 1
network 10.10.10.0 0.0.0.255 area 1
