Table 107, OSPF External Link State Database Table describes the non-configurable data
that is displayed in the External Link State Database (LSDB) table.
Click Update to update the page with the latest information on the switch.
Sequence The sequence number field is a signed 32-bit integer.
It is used to detect old and duplicate link state
advertisements. The larger the sequence number,
the more recent the advertisement.
Checksum The checksum is used to detect data corruption of an
advertisement. This corruption can occur while an
advertisement is being flooded, or while it is being
held in a router's memory. This field is the checksum
of the complete contents of the advertisement,
except the LS age field.
Options The Options field in the link state advertisement
header indicates which optional capabilities are
associated with the advertisement. The options are:
• Q — This enables support for QoS Traffic
Engineering.
• E — This describes the way AS-external-LSAs
are flooded.
• MC — This describes the way IP multicast
datagrams are forwarded according to the
standard specifications.
• O — This describes whether Opaque-LSAs are
supported.
• V — This describes whether OSPF++ extensions
for VPN/COS are supported.
