Field

Description

 

 

Priority

The priority assigned to the interface advertised in the hello

 

packets. When two routers attached to a network both

 

attempt to become the designated router, the router with the

 

highest priority takes precedence. A router whose priority

 

is set to 0 is ineligible to become the designated router on

 

the attached network.

 

 

DR

The IP interface address of the designated router selected

 

for the attached network. The designated router is selected

 

on broadcast networks by the hello protocol. Two pieces of

 

identification are kept for the designated router: the Router

 

ID and the IP interface address on the network. The

 

designated router advertises the link state for the network.

 

This network LSA is labeled with the designated router’s

 

IP address. The designated router is initialized to 0.0.0.0,

 

which indicates the lack of a designated router.

 

 

BR

The backup designated router selected for the attached

 

network. The backup designated router is also selected on

 

all broadcast networks by the hello protocol. All routers on

 

the attached network become adjacent to both the

 

designated router and the backup designated router. The

 

backup designated router becomes the designated router

 

when the current designated router fails. The backup

 

designated router is initialized to 0.0.0.0, indicating the

 

lack of a backup designated router.

 

 

Hello

The length of time, in seconds, between the hello packets

 

that the router sends on the interface. This interval is

 

advertised in hello packets sent out on this interface.

 

 

Dead

The number of seconds before the router’s neighbors

 

declare that the router is down, and when they stop

 

receiving the router’s hello packets. This interval is

 

advertised in hello packets sent out on this interface.
