Field

Description

 

value between brackets indicates the duration that the

 

purged LSP stays in the database before being removed.

ATT

This value represents the Attach bit. This value indicates that

 

the router is a Level 2 router and can reach other areas.

 

Level 1-only routers and Level 1-2 routers that have lost

 

connection to other Level 2 routers use the Attach bit to

 

find the closest Level 2 router. They point a default route to

 

the closest Level 2 router.

P

This value represents the P bit. This bit is always set to zero

 

as Dell Networking does not support area partition repair.

OL

This value represents the overload bit, determining

 

congestion. If the overload bit is set, other routers do not

 

use this system as a transit router when calculating routes.

Example

The bold sections identify that MultiTopology IS-IS is enabled.
