Configuring BFD for OSPFv3 on a virtual link by using IPv6 addressing
To configure BFD for OSPFv3 neighbors on a virtual link, you must first configure the virtual link between the disconnected backbone area routers and then enable BFD on the virtual link.
- R1 router-id—
1.1.1.1
- R2 router-id—
2.2.2.2
- R1 interface address facing R2—
10:1:1::1
- R2 interface address facing R1—
10:1:1::2
- R1 link local address—
10:1:1::1
- R2 link local address—
10:1:1::2
Virtual link is configured in a transit area. A virtual link chooses any address to reach other virtual link end points in the same transit area. Therefore, the source and destination addresses in a 3-router configuration or a more complex configuration are selected dynamically. You must ensure that you select the correct source and destination addresses for your BFD commands for OSPFv2 and OSPFv3 virtual links. To configure a BFD session between R1 and R2, perform the following steps in configuration mode.
Router | Step | Command |
---|---|---|
R1 | Create a BFD template called test . | See section Configuring the BFD template. |
R1 | Associate the BFD test template with the destination address of R2 and the source address of R1. |
|
R1 | Register R2 as a BFD neighbor. |
|
R1 | Commit the configuration. |
|
R1 | Save the configuration. |
|
R1 | Display the configuration. |
|
R2 | Create a BFD template called test . | See section Configuring the BFD template. |
R2 | Associate the BFD test template with the destination address of R1 and the source address of R2. |
|
R2 | Register R1 as a BFD neighbor. |
|
R2 | Commit the configuration. |
|
R2 | Save the configuration. |
|
R2 | Display the configuration. |
