OSPF version 2 is a routing protocol which described in
6
@asis{RFC2328} - @cite{OSPF Version 2}. OSPF is IGP (Interior Gateway
7
Protocols). Compared with RIP, OSPF can provide scalable network
8
support and faster convergence time. OSPF is widely used in large
9
networks such as ISP backbone and enterprise networks.

There is no @command{ospfd} specific options. Common options can be
26
specified (@pxref{Common Invocation Options}) to @command{ospfd}.
27
@command{ospfd} needs interface information from @command{zebra}. So
28
please make it sure @command{zebra} is running before invoking
31
Like other daemons, @command{ospfd} configuration is done in OSPF

specific configuration file @file{ospfd.conf}.

To start OSPF process you have to specify the OSPF router. As of this
39
writing, @command{ospfd} does not support multiple OSPF processes.
41
@deffn Command {router ospf} {}
42
@deffnx Command {no router ospf} {}
43
Enable or disable the OSPF process. @command{ospfd} does not yet
44
support multiple OSPF processes. So you can not specify an OSPF process

Quote: "Though the definition of the Area Border Router (ABR)
59
in the OSPF specification does not require a router with multiple
60
attached areas to have a backbone connection, it is actually
61
necessary to provide successful routing to the inter-area and
62
external destinations. If this requirement is not met, all traffic
63
destined for the areas not connected to such an ABR or out of the
64
OSPF domain, is dropped. This document describes alternative ABR
65
behaviors implemented in Cisco and IBM routers."

70
This rfc2328, the sucessor to rfc1583, suggests according to section
71
G.2 (changes) in section 16.4 a change to the path preference
72
algorithm that prevents possible routing loops that were possible in
73
the old version of OSPFv2. More specifically it demands that inter-area
74
paths and intra-area path are now of equal preference but still both
75
preferred to external paths.

This command specifies the OSPF enabled interface(s). If the interface has
100
an address from range 192.168.1.0/24 then the command below enables ospf
101
on this interface so router can provide network information to the other
102
ospf routers via this interface.
106
network 192.168.1.0/24 area 0.0.0.0
109
Prefix length in interface must be equal or bigger (ie. smaller network) than
110
prefix length in network statement. For example statement above doesn't enable
111
ospf on interface with address 192.168.1.1/23, but it does on interface with
112
address 192.168.1.129/25.

Summarize intra area paths from specified area into one Type-3 summary-LSA
124
announced to other areas. This command can be used only in ABR and ONLY
125
router-LSAs (Type-1) and network-LSAs (Type-2) (ie. LSAs with scope area) can
126
be summarized. Type-5 AS-external-LSAs can't be summarized - their scope is AS.
127

range are not advertised into other areas.
