static default vs bgp default

[Angel Lopez Delgado]

Hi Anand Buddhdev,

Change the preference in your static protocol configuration:

protocol static {
  route 0.0.0.0/0 unreachable;
  preference 99;
}

Before:

bird> show route 0.0.0.0/0
0.0.0.0/0          unreachable [static1 16:21:11] * (200)
                   unreachable [Customer 16:03:09 from 10.10.10.101]
(100/-) [i]

After:

bird> show route 0.0.0.0/0
0.0.0.0/0          unreachable [Customer 16:03:09 from 10.10.10.101] *
(100/-) [i]
                   unreachable [static1 16:22:17] (99)

You can set any value lower then 100.

Regards
