Quick hint : did you configure ip pim dr-priority command ?
thanks Date: Sat, 23 May 2009 12:07:36 +0200 From: [email protected] To: [email protected] 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 -- // Freedom Matters _________________________________________________________________ Hotmail® has a new way to see what's up with your friends. http://windowslive.com/Tutorial/Hotmail/WhatsNew?ocid=TXT_TAGLM_WL_HM_Tutorial_WhatsNew1_052009
