OSPF highlights
| Term | Explanation |
|---|---|
| Router-ID | Priority 1: Set with the router-id command |
| Priority 2: Highest loopback IP address | |
| Priority 3: Highest active interface IP address | |
| DR Designated Router | Priority 1: Highest priority. Set with the ip ospf priority command on the interface |
| Priority 2: Higest Router-ID | |
| BDR Backup Designated Router | Priority 1: Next highest priority. Set with the ip ospf priority command on the interface |
| Priority 2: Next higest Router-ID | |
| Communication | Uses multicast addresses 224.0.0.5 and 224.0.0.6 |
| 224.0.0.5 - Multicast to neighbours | |
| 224.0.0.6 - Multicast to DR and BDR. DR will relay the information to DROthers on 224.0.0.5 | |
| Metric | Uses bandwidth called cost - Default calculated as 108 / bandwidth |
| Metric is the accumulated cost to the destination network | |
| default highest bandwidth is 108 = 100 Mbps. Change with the auto-cost reference-bandwidth command. Remember to change on all routers. |
