Configuring Designated Router Election Priority for IS-IS
date_range
24-Nov-23
This example shows how to configure the designated router election priority for IS-IS.
Before you begin:
Configure network interfaces. See the Junos OS Interfaces Configuration Guide for Security Devices.
Enable IS-IS on the interfaces. See Example: Configuring IS-IS.
In this example, you configure the priority for logical interface ge-0/0/1.0 to be 100 and the level number to be 1. If this interface has the highest priority value, the router becomes the designated router for the Level 1 area.
To configure a designated router election priority for IS-IS:
content_copy zoom_out_map
[edit] user@host# set protocols isis interface ge-0/0/1.0 level 1 priority 100
Note:
- The default designated router election priority for IS-IS is 64. If you do not configure the priority value for an interface, by default IS-IS assigns the priority 64.
The router with the highest priority value is elected as the designated router.
