Multicast DR Problem..
I have a probelm with sparse-mode Multicast DR on a spoke point-to-point interface(R2) connecting to the FR hub on a multipoint interface(R1).
They see each other in show ip pim neighbor but R2(the spoke) sees no DR on its coonected interface to R1:
R2# sh ip pim int s0/0.1
Address Interface Ver/ Nbr Query DR DR
Mode Count Intvl Prior
126.96.36.199 Serial0/0.1 v2/S 1 30 1 0.0.0.0
Both with setting R1 as DR or R2 as DR (by ip pim dr-priority) and also using (ip pm nbma) on R1,I have this problem that causes the outgoing int for all entries in ip mroute table point to null.
What is the problem that R2 doesn`t see the DR and cause all outgoing interfaces to null?
