184 | * Add a line that should only be shown once, and always show at the end of the |
185 | * config block. | |
186 | * | |
187 | * If the line already exists, it will be moved to the end of the block. If it | |
188 | * does not exist, it will be added at the end of the block. | |
189 | * | |
190 | * Note that this only makes sense when there is just one such line that should | |
191 | * show up at the very end of a config block. Furthermore, if the same block | |
192 | * can show up from multiple daemons, all of them must make sure to print the | |
193 | * line at the end of their config, otherwise the line will show at the end of | |
194 | * the config for the last daemon that printed it. | |
195 | * | |
196 | * Here is a motivating example with the 'exit-vrf' command. Suppose we receive | |
197 | * a config from Zebra like so: | |
198 | * | |
199 | * vrf BLUE | |
200 | * ip route A | |
201 | * ip route B | |
202 | * exit-vrf | |
203 | * | |
204 | * Then suppose we later receive this config from PIM: | |
205 | * | |
206 | * vrf BLUE | |
207 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
208 | * exit-vrf | |
209 | * | |
210 | * Then we will combine them into one config block like so: | |
211 | * | |
212 | * vrf BLUE | |
213 | * ip route A | |
214 | * ip route B | |
215 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
216 | * exit-vrf | |
217 | * | |
218 | * Because PIM also sent us an 'exit-vrf', we noticed that we already had one | |
219 | * under the 'vrf BLUE' config block and so we moved it to the end of the | |
220 | * config block again. If PIM had neglected to send us 'exit-vrf', the result | |
221 | * would be this: | |
222 | * | |
223 | * vrf BLUE | |
224 | * ip route A | |
225 | * ip route B | |
226 | * exit-vrf | |
227 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
228 | * | |
229 | * Therefore, daemons that share config blocks must take care to consistently | |
230 | * print the same block terminators. | |
231 | * | |
232 | * Ideally this would be solved by adding a string to struct config that is | |
233 | * always printed at the end when dumping a config. However, this would only | |
234 | * work when the user is using integrated config. In the non-integrated config | |
235 | * case, daemons are responsible for writing their own config files, and so the | |
236 | * must be able to print these blocks correctly independently of vtysh, which | |
237 | * means they are the ones that need to handle printing the block terminators | |
238 | * and VTYSH needs to be smart enough to combine them properly. | |
