Note:

Since 100 is the default priority, line 9, which sets the priority to 100, is actually
unnecessary. It is included for illustration purposes only.

Configuration of Router R3

The following is the configuration file for Router R3 in

Figure 19

.

Lines 8 and 9 set the backup priority for Router R3 at 100 for virtual routers

VRID=1

and

VRID=2

. Since Router R1 has a priority of 200 for backing up virtual router

VRID=2

, and

Router R2 has a priority of 200 for backing up virtual router

VRID=1

, Router R3 is the

secondary Backup for both virtual routers

VRID=1

and

VRID=2

.

The following table shows the priorities for each virtual router configured on Router R3.

Note:

Since 100 is the default priority, lines 8 and 9, which set the priority to 100, are
actually unnecessary. They are included for illustration purposes only.
