5******
6
d50b2aa0 7:abbr:`OSPF (Open Shortest Path First)` version 2 is a routing protocol
a4c53928 8which is described in :rfc:`2328`. OSPF is an
d50b2aa0
QY		 9:abbr:`IGP (Interior Gateway Protocol)`. Compared with :abbr:`RIP`,
10:abbr:`OSPF` can provide scalable network support and faster
42fc5d26 11convergence times. OSPF is widely used in large networks such as
d50b2aa0 12:abbr:`ISP (Internet Service Provider)` backbone and enterprise
42fc5d26
QY		 13networks.

17.. _Configuring_ospfd:
18
19Configuring ospfd
20=================
21
22There are no *ospfd* specific options. Common options can be
23specified (:ref:`Common_Invocation_Options`) to *ospfd*.
24*ospfd* needs to acquire interface information from
25*zebra* in order to function. Therefore *zebra* must be
26running before invoking *ospfd*. Also, if *zebra* is
27restarted then *ospfd* must be too.
28
d50b2aa0 29Like other daemons, *ospfd* configuration is done in :abbr:`OSPF`
42fc5d26
QY		 30specific configuration file :file:`ospfd.conf`.
31
32.. _OSPF_router:
33
34OSPF router
35===========
36
37To start OSPF process you have to specify the OSPF router. As of this
38writing, *ospfd* does not support multiple OSPF processes.
39
40.. index:: Command {router ospf} {}
41
42Command {router ospf} {}
43.. index:: Command {no router ospf} {}
44
45Command {no router ospf} {}
46 Enable or disable the OSPF process. *ospfd* does not yet
47 support multiple OSPF processes. So you can not specify an OSPF process
48 number.
49
50.. index:: {OSPF Command} {ospf router-id `a.b.c.d`} {}
51
52{OSPF Command} {ospf router-id `a.b.c.d`} {}
53.. index:: {OSPF Command} {no ospf router-id} {}
54
55{OSPF Command} {no ospf router-id} {}
56 .. _ospf_router-id:
57
58 This sets the router-ID of the OSPF process. The
59 router-ID may be an IP address of the router, but need not be - it can
60 be any arbitrary 32bit number. However it MUST be unique within the
61 entire OSPF domain to the OSPF speaker - bad things will happen if
62 multiple OSPF speakers are configured with the same router-ID! If one
63 is not specified then *ospfd* will obtain a router-ID
64 automatically from *zebra*.
65
66.. index:: {OSPF Command} {ospf abr-type `type`} {}
67
68{OSPF Command} {ospf abr-type `type`} {}
69.. index:: {OSPF Command} {no ospf abr-type `type`} {}
70
71{OSPF Command} {no ospf abr-type `type`} {}
72 `type` can be cisco|ibm|shortcut|standard. The "Cisco" and "IBM" types
73 are equivalent.
74
75 The OSPF standard for ABR behaviour does not allow an ABR to consider
76 routes through non-backbone areas when its links to the backbone are
77 down, even when there are other ABRs in attached non-backbone areas
78 which still can reach the backbone - this restriction exists primarily
79 to ensure routing-loops are avoided.
80
81 With the "Cisco" or "IBM" ABR type, the default in this release of
dc1046f7 82 FRR, this restriction is lifted, allowing an ABR to consider
42fc5d26
QY		 83 summaries learnt from other ABRs through non-backbone areas, and hence
84 route via non-backbone areas as a last resort when, and only when,
85 backbone links are down.
86
87 Note that areas with fully-adjacent virtual-links are considered to be
88 "transit capable" and can always be used to route backbone traffic, and
89 hence are unaffected by this setting (:ref:`OSPF_virtual-link`).
90
91 More information regarding the behaviour controlled by this command can
ec8404d8 92 be found in :rfc:`3509`, and :t:`draft-ietf-ospf-shortcut-abr-02.txt`.
42fc5d26 93
d50b2aa0 94 Quote: "Though the definition of the :abbr:`ABR (Area Border Router)`
42fc5d26
QY		 95 in the OSPF specification does not require a router with multiple
96 attached areas to have a backbone connection, it is actually
97 necessary to provide successful routing to the inter-area and
98 external destinations. If this requirement is not met, all traffic
99 destined for the areas not connected to such an ABR or out of the
100 OSPF domain, is dropped. This document describes alternative ABR
101 behaviors implemented in Cisco and IBM routers."

a4c53928 109 :rfc:`2328`, the sucessor to :rfc:`1583`, suggests according
42fc5d26
QY		 110 to section G.2 (changes) in section 16.4 a change to the path
111 preference algorithm that prevents possible routing loops that were
112 possible in the old version of OSPFv2. More specifically it demands
113 that inter-area paths and intra-area backbone path are now of equal preference
114 but still both preferred to external paths.

134 .. _OSPF_passive-interface:
135
136 Do not speak OSPF interface on the
137 given interface, but do advertise the interface as a stub link in the
d50b2aa0 138 router-:abbr:`LSA (Link State Advertisement)` for this router. This
42fc5d26
QY		 139 allows one to advertise addresses on such connected interfaces without
140 having to originate AS-External/Type-5 LSAs (which have global flooding
141 scope) - as would occur if connected addresses were redistributed into
142 OSPF (:ref:`Redistribute_routes_to_OSPF`)@. This is the only way to
143 advertise non-OSPF links into stub areas.

148.. index:: {OSPF Command} {no timers throttle spf} {}
149
150{OSPF Command} {no timers throttle spf} {}
151 This command sets the initial `delay`, the `initial-holdtime`
152 and the `maximum-holdtime` between when SPF is calculated and the
153 event which triggered the calculation. The times are specified in
154 milliseconds and must be in the range of 0 to 600000 milliseconds.
155
156 The `delay` specifies the minimum amount of time to delay SPF
157 calculation (hence it affects how long SPF calculation is delayed after
158 an event which occurs outside of the holdtime of any previous SPF
159 calculation, and also serves as a minimum holdtime).
160
161 Consecutive SPF calculations will always be seperated by at least
162 'hold-time' milliseconds. The hold-time is adaptive and initially is
163 set to the `initial-holdtime` configured with the above command.
164 Events which occur within the holdtime of the previous SPF calculation
165 will cause the holdtime to be increased by `initial-holdtime`, bounded
166 by the `maximum-holdtime` configured with this command. If the adaptive
a8c90e15 167 hold-time elapses without any SPF-triggering event occuring then
42fc5d26 168 the current holdtime is reset to the `initial-holdtime`. The current
a8c90e15 169 holdtime can be viewed with :ref:`show_ip_ospf`, where it is expressed as
42fc5d26
QY		 170 a multiplier of the `initial-holdtime`.
171

175 timers throttle spf 200 400 10000
a8c90e15 176
42fc5d26
QY		 177
178 In this example, the `delay` is set to 200ms, the @var{initial
179 holdtime} is set to 400ms and the `maximum holdtime` to 10s. Hence
180 there will always be at least 200ms between an event which requires SPF
181 calculation and the actual SPF calculation. Further consecutive SPF
182 calculations will always be seperated by between 400ms to 10s, the
183 hold-time increasing by 400ms each time an SPF-triggering event occurs
184 within the hold-time of the previous SPF calculation.
185
dc1046f7 186 This command supercedes the *timers spf* command in previous FRR
42fc5d26
QY		 187 releases.

29adcd50 189.. index:: {OSPF Command} {max-metric router-lsa [on-startup|on-shutdown] (5-86400)} {}

196
197{OSPF Command} {no max-metric router-lsa [on-startup|on-shutdown|administrative]} {}
a4c53928 198 This enables :rfc:`3137` support,
42fc5d26
QY		 199 where the OSPF process describes its transit links in its router-LSA as
200 having infinite distance so that other routers will avoid calculating
201 transit paths through the router while still being able to reach
202 networks through the router.
203
204 This support may be enabled administratively (and indefinitely) or
205 conditionally. Conditional enabling of max-metric router-lsas can be
206 for a period of seconds after startup and/or for a period of seconds
a8c90e15 207 prior to shutdown.
42fc5d26
QY		 208
209 Enabling this for a period after startup allows OSPF to converge fully
210 first without affecting any existing routes used by other routers,
211 while still allowing any connected stub links and/or redistributed
212 routes to be reachable. Enabling this for a period of time in advance
213 of shutdown allows the router to gracefully excuse itself from the OSPF
a8c90e15 214 domain.
42fc5d26
QY		 215
216 Enabling this feature administratively allows for administrative
217 intervention for whatever reason, for an indefinite period of time.
218 Note that if the configuration is written to file, this administrative
219 form of the stub-router command will also be written to file. If
220 *ospfd* is restarted later, the command will then take effect
221 until manually deconfigured.
222
223 Configured state of this feature as well as current status, such as the
224 number of second remaining till on-startup or on-shutdown ends, can be
225 viewed with the :ref:`show_ip_ospf` command.

234
235 This sets the reference

237 equivalent to an OSPF cost of 1, specified in Mbits/s. The default is
238 100Mbit/s (i.e. a link of bandwidth 100Mbit/s or higher will have a
239 cost of 1. Cost of lower bandwidth links will be scaled with reference
240 to this cost).
241
242 This configuration setting MUST be consistent across all routers within the

258
259 This command specifies the OSPF enabled interface(s). If the interface has
260 an address from range 192.168.1.0/24 then the command below enables ospf
261 on this interface so router can provide network information to the other
262 ospf routers via this interface.

QY		 269
270 Prefix length in interface must be equal or bigger (ie. smaller network) than
271 prefix length in network statement. For example statement above doesn't enable
272 ospf on interface with address 192.168.1.1/23, but it does on interface with
273 address 192.168.1.129/25.
274
275 Note that the behavior when there is a peer address
276 defined on an interface changed after release 0.99.7.
277 Currently, if a peer prefix has been configured,
278 then we test whether the prefix in the network command contains
279 the destination prefix. Otherwise, we test whether the network command prefix
a8c90e15 280 contains the local address prefix of the interface.
42fc5d26
