Hi,
This lab talks about carrying the rip v1 broadcast in a multicast. I
am drawing a little topology here for others who may not have access
to the book.
R1
|
|
|Fa0/0
R6----------------(Vi1)---R5
R5 is supposed to get a RIP v1 update from R1 which is running RipV1.
R6 and and R5 are running dense-mode multicast. In the solution it
converts broadcast at R6 into multicast 224.9.9.9 udp and then at R5
this multicast is converted to broadcast again to subnet of R5's
virtual-template. I understand this.
The piece which i don't understand is enabling "ip directed-broadcast"
at R6 fa0/0 interface and R5's virtual-template 1.
What i undestand is that its required only when a router is supposed
to brroadcast a packet on some segment when it receives a subnetted
broadcast. Comments please?
Thanks
-Anand
