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

18 | Configuring ospfd | |
19 | ================= | |
20 | ||
c1a54c05 | 21 | There are no *ospfd* specific options. Common options can be specified |
0efdf0fe | 22 | (:ref:`common-invocation-options`) to *ospfd*. *ospfd* needs to acquire |
c1a54c05 QY |
23 | interface information from *zebra* in order to function. Therefore *zebra* must |
24 | be running before invoking *ospfd*. Also, if *zebra* is restarted then *ospfd* | |
25 | must be too. | |
42fc5d26 | 26 | |
c1a54c05 QY |
27 | Like other daemons, *ospfd* configuration is done in :abbr:`OSPF` specific |
28 | configuration file :file:`ospfd.conf`. | |

32 | OSPF router | |
33 | =========== | |
34 | ||
c1a54c05 | 35 | To start OSPF process you have to specify the OSPF router. As of this |
42fc5d26 QY |
36 | writing, *ospfd* does not support multiple OSPF processes. |

44 | Enable or disable the OSPF process. *ospfd* does not yet |
45 | support multiple OSPF processes. So you can not specify an OSPF process | |
46 | number. | |

c1a54c05 QY |
54 | This sets the router-ID of the OSPF process. The |
55 | router-ID may be an IP address of the router, but need not be - it can | |
56 | be any arbitrary 32bit number. However it MUST be unique within the | |
57 | entire OSPF domain to the OSPF speaker - bad things will happen if | |
58 | multiple OSPF speakers are configured with the same router-ID! If one | |
59 | is not specified then *ospfd* will obtain a router-ID | |
60 | automatically from *zebra*. | |

68 | `type` can be cisco|ibm|shortcut|standard. The "Cisco" and "IBM" types |
69 | are equivalent. | |
70 | ||
71 | The OSPF standard for ABR behaviour does not allow an ABR to consider | |
72 | routes through non-backbone areas when its links to the backbone are | |
73 | down, even when there are other ABRs in attached non-backbone areas | |
74 | which still can reach the backbone - this restriction exists primarily | |
75 | to ensure routing-loops are avoided. | |
76 | ||
d1e7591e QY |
77 | With the "Cisco" or "IBM" ABR type, the default in this release of FRR, this |
78 | restriction is lifted, allowing an ABR to consider summaries learned from | |
79 | other ABRs through non-backbone areas, and hence route via non-backbone | |
80 | areas as a last resort when, and only when, backbone links are down. | |
6ee602cd QY |
81 | |
82 | Note that areas with fully-adjacent virtual-links are considered to be | |
83 | "transit capable" and can always be used to route backbone traffic, and | |
84 | hence are unaffected by this setting (:clicmd:`area A.B.C.D virtual-link A.B.C.D`). | |
85 | ||
86 | More information regarding the behaviour controlled by this command can | |
87 | be found in :rfc:`3509`, and :t:`draft-ietf-ospf-shortcut-abr-02.txt`. | |
88 | ||
89 | Quote: "Though the definition of the :abbr:`ABR (Area Border Router)` | |
90 | in the OSPF specification does not require a router with multiple | |
91 | attached areas to have a backbone connection, it is actually | |
92 | necessary to provide successful routing to the inter-area and | |
93 | external destinations. If this requirement is not met, all traffic | |
94 | destined for the areas not connected to such an ABR or out of the | |
95 | OSPF domain, is dropped. This document describes alternative ABR | |
96 | behaviors implemented in Cisco and IBM routers." | |

105 | to section G.2 (changes) in section 16.4 a change to the path |
106 | preference algorithm that prevents possible routing loops that were | |
107 | possible in the old version of OSPFv2. More specifically it demands | |
108 | that inter-area paths and intra-area backbone path are now of equal preference | |

129 | Do not speak OSPF interface on the |
130 | given interface, but do advertise the interface as a stub link in the | |
131 | router-:abbr:`LSA (Link State Advertisement)` for this router. This | |
132 | allows one to advertise addresses on such connected interfaces without | |
133 | having to originate AS-External/Type-5 LSAs (which have global flooding | |
134 | scope) - as would occur if connected addresses were redistributed into | |
135 | OSPF (:ref:`redistribute-routes-to-ospf`). This is the only way to | |
136 | advertise non-OSPF links into stub areas. | |

142 | .. clicmd:: no timers throttle spf | |
143 | ||
144 | This command sets the initial `delay`, the `initial-holdtime` | |
145 | and the `maximum-holdtime` between when SPF is calculated and the | |
146 | event which triggered the calculation. The times are specified in | |
147 | milliseconds and must be in the range of 0 to 600000 milliseconds. | |
148 | ||
149 | The `delay` specifies the minimum amount of time to delay SPF | |
150 | calculation (hence it affects how long SPF calculation is delayed after | |
151 | an event which occurs outside of the holdtime of any previous SPF | |
152 | calculation, and also serves as a minimum holdtime). | |
153 | ||
d1e7591e | 154 | Consecutive SPF calculations will always be separated by at least |
c1a54c05 QY |
155 | 'hold-time' milliseconds. The hold-time is adaptive and initially is |
156 | set to the `initial-holdtime` configured with the above command. | |
157 | Events which occur within the holdtime of the previous SPF calculation | |
158 | will cause the holdtime to be increased by `initial-holdtime`, bounded | |
159 | by the `maximum-holdtime` configured with this command. If the adaptive | |
d1e7591e | 160 | hold-time elapses without any SPF-triggering event occurring then |
c1a54c05 | 161 | the current holdtime is reset to the `initial-holdtime`. The current |
6ee602cd | 162 | holdtime can be viewed with :clicmd:`show ip ospf`, where it is expressed as |
c1a54c05 | 163 | a multiplier of the `initial-holdtime`. |

171 | In this example, the `delay` is set to 200ms, the initial holdtime is set to | |
172 | 400ms and the `maximum holdtime` to 10s. Hence there will always be at least | |
173 | 200ms between an event which requires SPF calculation and the actual SPF | |
d1e7591e | 174 | calculation. Further consecutive SPF calculations will always be separated |
c1a54c05 QY |
175 | by between 400ms to 10s, the hold-time increasing by 400ms each time an |
176 | SPF-triggering event occurs within the hold-time of the previous SPF | |

c1a54c05 QY |
191 | This enables :rfc:`3137` support, where the OSPF process describes its |
192 | transit links in its router-LSA as having infinite distance so that other | |
193 | routers will avoid calculating transit paths through the router while still | |
194 | being able to reach networks through the router. | |
42fc5d26 | 195 | |
c1a54c05 QY |
196 | This support may be enabled administratively (and indefinitely) or |
197 | conditionally. Conditional enabling of max-metric router-lsas can be for a | |
198 | period of seconds after startup and/or for a period of seconds prior to | |
199 | shutdown. | |
42fc5d26 | 200 | |
c1a54c05 QY |
201 | Enabling this for a period after startup allows OSPF to converge fully first |
202 | without affecting any existing routes used by other routers, while still | |
203 | allowing any connected stub links and/or redistributed routes to be | |
204 | reachable. Enabling this for a period of time in advance of shutdown allows | |
205 | the router to gracefully excuse itself from the OSPF domain. | |
42fc5d26 | 206 | |
c1a54c05 QY |
207 | Enabling this feature administratively allows for administrative |
208 | intervention for whatever reason, for an indefinite period of time. Note | |
209 | that if the configuration is written to file, this administrative form of | |
210 | the stub-router command will also be written to file. If *ospfd* is | |
211 | restarted later, the command will then take effect until manually | |
212 | deconfigured. | |
42fc5d26 | 213 | |
c1a54c05 QY |
214 | Configured state of this feature as well as current status, such as the |
215 | number of second remaining till on-startup or on-shutdown ends, can be | |
6ee602cd | 216 | viewed with the :clicmd:`show ip ospf` command. |

d1e7591e | 256 | Prefix length in interface must be equal or bigger (i.e. smaller network) than |
c1a54c05 QY |
257 | prefix length in network statement. For example statement above doesn't enable |
258 | ospf on interface with address 192.168.1.1/23, but it does on interface with | |
259 | address 192.168.1.129/25. | |
42fc5d26 | 260 | |
c1a54c05 QY |
261 | Note that the behavior when there is a peer address |
262 | defined on an interface changed after release 0.99.7. | |
263 | Currently, if a peer prefix has been configured, | |
264 | then we test whether the prefix in the network command contains | |
265 | the destination prefix. Otherwise, we test whether the network command prefix | |
266 | contains the local address prefix of the interface. | |
42fc5d26 | 267 | |
c1a54c05 | 268 | In some cases it may be more convenient to enable OSPF on a per |
