I'm part of a group of sites that are trying to multicast to each other. I'm showing on the neighbor table and in mroute on one of the routers between locations, but am unable to get my streams to be picked up by others. I *can* see the stream from one of the other sites. While I wait for:
working site's television engineer to track down the person that set up their router
and
yes/no confirmation that my latest config is working (just heard. it's a no)
I thought I'd post it here. Very last change was to enable bidirectional multicast (which worked for someone in another thread).
Any insights would be tremendously appreciated.
First, a factory reset, followed by
gave myself a login, then pasted the following:
hostname MCST-ONLY-01
ip multicast-routing
ip pim rp-address 199.x.x.x
ip route 0.0.0.0 0.0.0.0 199.x.x.x
ip mroute 0.0.0.0 0.0.0.0 199.x.x.x
ip pim bidir-enable
interface f8
ip address 199.x.x.x 255.255.255.248
ip pim sparse-mode
interface vlan1
ip address 10.10.10.1 255.255.255.0
ip pim sparse-mode
resulting in the following config:
MCST-ONLY-01#show running-conf

Multicasting networks have more design issues than configuration problems.
The configuration is fine. But we need to have a clear understanding of what we are trying to achieve and how the traffic will flow fron the source to this router.
My Questions : -
ip mroute 0.0.0.0 0.0.0.0 199.x.x.x
This 199 IP, is it part of your AS ?
Does this peer have pim enabled ?
Do we have pim neighborship to that neighbor (show ip pim neighbor)?
Is it different from (ip route 0.0.0.0 0.0.0.0 199.x.x.x) ?
Where is RP 199.8.216.31 located in the network?
Does this router have receivers for the Group G?(show ip igmp groups)
Do you see (*,G) joins forwarded to pim neighbor upstream?
Does the RP has (S,G) for the group?
Is the RPF correct in the transit path from this router to RP?
Why are you trying to run pim in bidir mode?
Can you post a network diagram ?
Also please post a mtrace 199.8.216.31 and a trace from RP to interface FastEthernet8 IP.
7. Do you see (*,G) joins forwarded to pim neighbor upstream?
8. Does the RP has (S,G) for the group?
9. Is the RPF correct in the transit path from this router to RP?
These have been forwarded to the ISP
10. Why are you trying to run pim in bidir mode?
no good reason. saw it mentioned in another thread and assumed that since I was getting data in but not sending it out that it would be worth trying. Will switch it off if it's not doing me any good.
11. Can you post a network diagram ?

12. Also please post a mtrace 199.8.216.31 and a trace from RP to interface FastEthernet8 IP.
MCST-ONLY-01#mtrace 199.8.216.31
Type escape sequence to abort.
Mtrace from 199.8.216.31 to 199.8.201.100 via RPF
From source (?) to destination (?)
Querying full reverse path...
0 199.8.201.100
-1 199.8.201.100 PIM [default]
-2 199.8.201.97 None No route
I hope at least some of this is helpful. Thanks again.
It seems the issue is not on your router but on the ISP router(199.8.201.97) connected to yours.
Possible issues -
Incorrect RPF for the RP
Pim not enabled on path upstream to RP
Please do a traceroute and ping from your router to 199.8.216.31 and let me know of the output.
How to be sure that issue is with the ISP -
traceroute and mtrace should have same results complete path, the hop where you see a deflection could potentially be the INTERESTING-HOP with problem
traceroute and mtrace should have same results for complete path the hop where you see a deflection could potentially be the INTERESTING-HOP with problem
Note that if the above traces are incomplete as in your example above especially mtrace then it means multicast RPF is broken
show ip mroute 233.6.231.4 should have the (*,G) as the receivers joins a group and as soon as the router receives the multicast stream it should have (S,G)
