#
# 2018-06-15: changed item from neighbor id to neighbor ip
# added events as perfdata (incl. metrics file)
# moved part of the output to long output
# a little code cleanup to better match coding guide lines
# 2019-11-03: moved 'events' from infotext to longoutput
# 2020-07-26: added parse section, alias, wato for alias and state

A bit mask corresponding to the neighbor's options field.
Bit 0, if set, indicates that the system will operate on Type of Service metrics other than TOS 0.
If zero, the neighbor will ignore all metrics except the TOS 0 metric.
Bit 1, if set, indicates that the associated area accepts and operates on external information;
if zero, it is a stub area.
Bit 2, if set, indicates that the system is capable of routing IP multicast datagrams, that is that it
implements the multicast extensions to OSPF.
Bit 3, if set, indicates that the associated area is an NSSA. These areas are capable of carrying type-7
external advertisements, which are translated into type-5 external advertisements at NSSA borders.
