Hi there,
Nope, didnt touch the priority. Only manually asked it to use igmp v1
and therefor expected it to use the pim election to use the dr and be
querier.
Thanks,

Subject: [OSL | CCIE_RS] DR and Assert.
Hi All,
I am trying to tackle my enemy number 1... Multicast. I am a bit
confused about when two routers are connected to the same
multiaccess network.
As far as I understand it, when using PIM-DM, an assert message is
being sent out, with the metric (AD + metric) of each router. The
one with the best metric wins, in case of a tie, the router with the
highest IP wins.
Then later on in the material, in the description of PIM-SM, it
says it elects a DR, based solely on the highest IP address. This
one will be the one that sends a join up the tree towards the RP.
Are assert messages not used in PIM-SM at all? and I know from the
material that a DR is still being elected in PIM-DM, but it should
only be used when IGMPv1 is being used to select the current querier.
Is this correctly understood?
Also, I have tried a pure PIM-DM network, and used IGMPv1 on my
multiaccess-network towards the receiver. However, what happens is
that both routers end up sending queriers onto the network, and not
the DR elected router as I expected.
All in all, a bit confused :)
Sincerely,
Kim Pedersen
