134 | * Add a line that should only be shown once, and always show at the end of the |
135 | * config block. | |
136 | * | |
137 | * If the line already exists, it will be moved to the end of the block. If it | |
138 | * does not exist, it will be added at the end of the block. | |
139 | * | |
140 | * Note that this only makes sense when there is just one such line that should | |
141 | * show up at the very end of a config block. Furthermore, if the same block | |
142 | * can show up from multiple daemons, all of them must make sure to print the | |
143 | * line at the end of their config, otherwise the line will show at the end of | |
144 | * the config for the last daemon that printed it. | |
145 | * | |
146 | * Here is a motivating example with the 'exit-vrf' command. Suppose we receive | |
147 | * a config from Zebra like so: | |
148 | * | |
149 | * vrf BLUE | |
150 | * ip route A | |
151 | * ip route B | |
152 | * exit-vrf | |
153 | * | |
154 | * Then suppose we later receive this config from PIM: | |
155 | * | |
156 | * vrf BLUE | |
157 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
158 | * exit-vrf | |
159 | * | |
160 | * Then we will combine them into one config block like so: | |
161 | * | |
162 | * vrf BLUE | |
163 | * ip route A | |
164 | * ip route B | |
165 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
166 | * exit-vrf | |
167 | * | |
168 | * Because PIM also sent us an 'exit-vrf', we noticed that we already had one | |
169 | * under the 'vrf BLUE' config block and so we moved it to the end of the | |
170 | * config block again. If PIM had neglected to send us 'exit-vrf', the result | |
171 | * would be this: | |
172 | * | |
173 | * vrf BLUE | |
174 | * ip route A | |
175 | * ip route B | |
176 | * exit-vrf | |
177 | * ip msdp mesh-group MyGroup member 1.2.3.4 | |
178 | * | |
179 | * Therefore, daemons that share config blocks must take care to consistently | |
180 | * print the same block terminators. | |
181 | * | |
182 | * Ideally this would be solved by adding a string to struct config that is | |
183 | * always printed at the end when dumping a config. However, this would only | |
184 | * work when the user is using integrated config. In the non-integrated config | |
185 | * case, daemons are responsible for writing their own config files, and so the | |
186 | * must be able to print these blocks correctly independently of vtysh, which | |
187 | * means they are the ones that need to handle printing the block terminators | |
188 | * and VTYSH needs to be smart enough to combine them properly. | |
