Dell Networking 7048 - Configuring Flood Blocking

1014 Configuring OSPF and OSPFv3
LS Seq Number: 0x80000003
Checksum: 0x78f8
Length: 28
Network Mask: 255.255.0.0
Metric: 0
The cost can be set to the maximum value, 16,777,215, which is LSInfinity.
Since OSPF cannot send a type 3 summary LSA with this metric (according
to RFC 2328), the summary LSA is flushed. The individual routes are not re-
advertised.
