lab 5 EIGRP stub

EIGRP Stub

A stub router sends a special peer information packet to all neighboring routers to report its status as a stub router.

Any neighbor that receives a packet informing it of the stub status does not query the stub router for any routes.

Router(config-router)#
eigrp stub [receive-only|connected|static|summary]

 

 

 

• receive-only: Prevents the stub from sending any type of route.

• connected: Permits stub to send connected routes (may still need to redistribute).

• static: Permits stub to send static routes (must still redistribute).

• summary: Permits stub to send summary routes.

• Default is connectedand summary.
