Re: PIM BiDir Problem

Joe,
SW4 was the DR, changed it to SW2 but still no luck, pings are still timing
out.

SW4#sh ip pim int

Address Interface Ver/ Nbr Query DR DR
                                          Mode Count Intvl Prior
150.1.10.10 Loopback0 v2/S 0 30 1
150.1.10.10
*155.1.108.10 Port-channel1 v2/S 1 30 1
155.1.108.8*
155.1.10.10 Vlan10 v2/S 0 30 1
155.1.10.10
