@acronym{ISIS,Intermediate System to Intermediate System} is a routing protocol
|
||||
which is described in @cite{ISO10589, RFC1195, RFC5308}. ISIS is an
|
||||
@acronym{IGP,Interior Gateway Protocol}. Compared with @acronym{RIP},
|
||||
@acronym{ISIS} can provide scalable network support and faster
|
||||
convergence times like @acronym{OSPF}. ISIS is widely used in large networks such as
|
||||
@acronym{ISP,Internet Service Provider} and carrier backbone networks.

|

There are no @command{isisd} specific options. Common options can be
|
||||
specified (@pxref{Common Invocation Options}) to @command{isisd}.
|
||||
@command{isisd} needs to acquire interface information from
|
||||
@command{zebra} in order to function. Therefore @command{zebra} must be
|
||||
running before invoking @command{isisd}. Also, if @command{zebra} is
|
||||
restarted then @command{isisd} must be too.
|
||||
|
||||
Like other daemons, @command{isisd} configuration is done in @acronym{ISIS}
|
||||
specific configuration file @file{isisd.conf}.
