Subject: Re: Statically mapping broadcasts
Hi,
When you configure frame-relay map commands on the spoke routers you
only need to specify one broadcast key word as it is mapped to the same
DLCI
ex.
frame-relay map ip 1.1.1.1 301 broadcast
frame-relay map ip 1.1.1.2 301
If you configure broadcast key word on all the map statements, it will
send redundant broadcast.
ex.
frame-relay map ip 1.1.1.1 301 broadcast
frame-relay map ip 1.1.1.2 301 broadcast
On the hub router, you need the broadcast key word for all the
separate DLCI mappings
frame-relay map ip 1.1.1.2 102 broadcast
frame-relay map ip 1.1.1.3 103 broadcast

Experts,
Working in IEWB VOL2,
Reading in the task:
"Do not send any redundant broadcast traffic from the spokes to the
hub"?
I understood not to "statically map" broadcast traffic from spokes to
the hub.
However, when configuring OSPF later, not to use neighbor, requires
broadcast to be correctly mapped for the 224.0.0.5 hellos to flow.
Any comment what they mean by: "Do not send any redundant broadcast
traffic from the spokes to the hub"?
Cheers,
Peter
