Hello everyone! In today's article I will show failover configuration and I am going to show a several example of failover in the next articles. We leave the current configuration L3VPN for testing and will add the server (Centos) is connected to the router CE1. On the server will use the script "pretty ping" because the failover time is measured in milliseconds.
Here is an example of a modified configuration PE1 and PE3. Routers PE3 and PE4 left unchanged also added only setting BFD protocol over OSPF, because of I use virtual environment
Here's what I got:
Then I shutdown the interface between PE3 and PE6:
And we see that we have switched to the backup path:
And test launched from the server, we see that they have lost three packets - all trigger about 60 milliseconds:
