Hey everybody,
Source-S1-----H-----S2-Client
This isn't a lab question, but I couldn't think of a better place to ask
this. :) I'm at work with some cat 6509s connected Hub and spoke. I'm
setting up a larger test bed for IPv6 multicast legacy application testing,
but having problems getting just this small Hub and spoke pilot working.
I've configured the Hub and a static IPv6 RP and the other two spokes to
point at it statically. I see ipv6 pim neighbors to each other and the
dynamic tunnels come up. I'm using a Spirent Testcenter to generate ipv6
multicast traffic at one site and capture the traffic at another site. I've
also tried IPERF ipv6 multicast generator software with the same weird
results detailed below.
It seems that the client at spoke 2 will not join and I get no (*,G) entry,
not even on the clients DR. I've tried to look at mld and see no problems,
but I probably don't know exactly what to look for either. Now here's the
kicker, as soon as I configure "ipv6 mld join-group ff0e::1" on the vlan
interface, the client starts receiving traffic. What gets me is why I have
to manually configure that for the vlan to join the group. Shouldn't MLD
take care of all this? On the RP I see the source registering when I start
sending, but of course no clients registering on the RP until I configure
the ipv6 mld join-group command. I guess I have a workaround for now, but
it would be nice to get MLD working properly to fore go all the static join
groups I'll be doing. As far as config on the routers, all I did was ipv6
multicast-routing, ipv6 pim rp-address 2001:480:10:10::1, and ipv6
unicast-routing. From my understaning IPv6 is enabled by default on all
interfaces and I can verify this with the "sh ipv6 pim int | i on" command.
My current software version is 12.2(18)SXF8 advanced enterprise services.
We have 512 megs of DRAM and 512 megs of flash. Any help is appreciated as
I'm pulling out my hair on this, or what's left of it. :)
regards,
Dale
