RE: Multicast - Verify Helper Map

I modified the doc cd example to include converting rip version 1's
broadcast to multicast and remapping the ttl to 16 hops. So my answer is
other than an SLA can you run broadcast rip on the router "before the router
converting" and on router on the other side of the router receiving the
multicast and converting back to broadcast.

If this works the rip v1 routes should make it from R1 to R4
Shall I lab this up, or would you like the honor of testing it?

(where R2 -> R3 is doing the conversion)

First Hop Router Configuration (R2)

interface ethernet 0

 ip address 126.1.22.1 255.255.255.0

 ip pim sparse-mode

 ip multicast helper-map broadcast 239.254.2.5 105 ttl 16

access-list 105 permit udp any any eq 520

ip forward-protocol udp 520

Last Hop Router Configuration (R3)

interface ethernet 1

 ip address 126.1.26.1 255.255.255.0

 ip pim sparse-mode

 ip multicast helper-map 239.254.2.5 126.1.28.255 105

interface ethernet 2

 ip address 126.1.28.1 255.255.255.0

 ip directed-broadcast

access-list 105 permit udp any any eq 520

ip forward-protocol udp 520

Hi Expert;

Verify Helper Map

how to verify / check the conversion of broadcast to multicast and multicast
to broadcast

Any Other method Beside using ip sla monitor + debug to verify the multicast
helper map ?

Thanks
