OK, I have done that, but then I run into the problem that R4, R5 do not see
that auto-RP maps.
R6(s1/0)--------(s0/0)R4
\-------(s0)R5
Also, the solution provided (which I don't rule out to be incorrect) does
not have R2 config's as an RP MA. The solution lists R1 as the RP MA as
well as C-RP. Is there any conflicts if there is multiple RP MAs?

R6 SHOULD KNOW THE MAPPING AGAENT IN ORDER TO GET RP INFORMATION. FROM WHAT
I SETT R6 HAS ONLY CONNECTIVITY TO R2 AND NOT R1 SO MAKE R2 THE MAPPING
AGENT.

Subject: IP Multicast - Auto -RP problems
I am working on multicast and having quite a few problems. Here is the
topo:
R1(e1)------(e0)R2(s0)----------(s1/0)R6
R1 is configured as a C-RP and the mapping agent:
interface Loopback0
ip address 100.0.0.1 255.255.255.255
ip pim sparse-dense-mode
!
interface Ethernet0
description ethernet to BB1
ip address 140.10.1.1 255.255.255.0
ip pim sparse-dense-mode
!
interface Ethernet1
description ethernet connected to R2
ip address 140.10.12.1 255.255.255.0
ip pim sparse-dense-mode
!
ip pim send-rp-announce Loopback0 scope 16 group-list 10
ip pim send-rp-discovery scope 16
R2 does not appear to be passing on the send-RP-discovery over the Frame
link to R6, but does have the auto-RP maps:
r2#sh ip pim rp map
PIM Group-to-RP Mappings
Group(s) 224.12.12.12/32
RP 100.0.0.1 (?), v2v1
Info source: 140.10.12.1 (?), via Auto-RP
Uptime: 01:13:35, expires: 00:02:55
Group(s) 224.12.12.13/32
RP 100.0.0.1 (?), v2v1
Info source: 140.10.12.1 (?), via Auto-RP
Uptime: 01:13:36, expires: 00:02:59
R6 sees R2 as a PIM neighbor, but will not map the auto-RP. I have tried to
set the FR interfaces to 'ip pim parse-mode' with 'ip pim nbma' and still no
luck:
r6#sh ip pim rp map
PIM Group-to-RP Mappings
r6#sh ip pim nei
PIM Neighbor Table
Neighbor Address Interface Uptime Expires Ver Mode
140.10.245.4 Serial1/0 01:02:44 00:01:32 v2
140.10.245.5 Serial1/0 01:02:44 00:01:30 v2
140.10.245.2 Serial1/0 01:02:44 00:01:33 v2
I am out of ideas and to top it off, the solutions do not have R2 or R6
configured as a mapping agent: below are the config for R2, R6:
R2:
interface Ethernet0
description to R1 E0 (crossover)
ip address 140.10.12.2 255.255.255.0
