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. | |

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

105 | :rfc:`2328`, the sucessor to :rfc:`1583`, suggests according |
106 | to section G.2 (changes) in section 16.4 a change to the path | |
107 | preference algorithm that prevents possible routing loops that were | |
108 | possible in the old version of OSPFv2. More specifically it demands | |
109 | that inter-area paths and intra-area backbone path are now of equal preference | |

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

141 | ||
142 | .. index:: no timers throttle spf | |
143 | .. clicmd:: no timers throttle spf | |
144 | ||
145 | This command sets the initial `delay`, the `initial-holdtime` | |
146 | and the `maximum-holdtime` between when SPF is calculated and the | |
147 | event which triggered the calculation. The times are specified in | |
148 | milliseconds and must be in the range of 0 to 600000 milliseconds. | |
149 | ||
150 | The `delay` specifies the minimum amount of time to delay SPF | |
151 | calculation (hence it affects how long SPF calculation is delayed after | |
152 | an event which occurs outside of the holdtime of any previous SPF | |
153 | calculation, and also serves as a minimum holdtime). | |
154 | ||
155 | Consecutive SPF calculations will always be seperated by at least | |
156 | 'hold-time' milliseconds. The hold-time is adaptive and initially is | |
157 | set to the `initial-holdtime` configured with the above command. | |
158 | Events which occur within the holdtime of the previous SPF calculation | |
159 | will cause the holdtime to be increased by `initial-holdtime`, bounded | |
160 | by the `maximum-holdtime` configured with this command. If the adaptive | |
161 | hold-time elapses without any SPF-triggering event occuring then | |
162 | the current holdtime is reset to the `initial-holdtime`. The current | |
6ee602cd | 163 | holdtime can be viewed with :clicmd:`show ip ospf`, where it is expressed as |
c1a54c05 | 164 | a multiplier of the `initial-holdtime`. |

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

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

247 | This command specifies the OSPF enabled interface(s). If the interface has |
248 | an address from range 192.168.1.0/24 then the command below enables ospf | |
249 | on this interface so router can provide network information to the other | |
250 | ospf routers via this interface. | |

257 | Prefix length in interface must be equal or bigger (ie. smaller network) than |
258 | prefix length in network statement. For example statement above doesn't enable | |
259 | ospf on interface with address 192.168.1.1/23, but it does on interface with | |
260 | address 192.168.1.129/25. | |
42fc5d26 | 261 | |
c1a54c05 QY |
262 | Note that the behavior when there is a peer address |
263 | defined on an interface changed after release 0.99.7. | |
264 | Currently, if a peer prefix has been configured, | |
265 | then we test whether the prefix in the network command contains | |
266 | the destination prefix. Otherwise, we test whether the network command prefix | |
267 | contains the local address prefix of the interface. | |
42fc5d26 | 268 | |
c1a54c05 | 269 | In some cases it may be more convenient to enable OSPF on a per |

1029 | prefix with /32 corresponding to a loopback interface are currently | |
1030 | supported. The 'no-php-flag' means NO Penultimate Hop Popping that allows SR | |
1031 | node to request to its neighbor to not pop the label. | |
