Folks,

how do you verify mcast ? i can see the mroute to see
if a group is dense/sparse. what about bidir ? and ssm
? i do see the mroute options B for bidir and s for
ssm but after configuring bidir i do not see the bidir
group.
                e1--ip igmp-join 224.6.6.6
               /
R1_e0_____e0_R2 (RP)

R1
ip multicast-routing
!
ip pim bidir-enable
!
e0
ip pim sparse-dense

---
R2
ip multicast-routing
!
ip pim bidir-enable
ip pim send-rp-announce Ethernet0 scope 1
ip pim send-rp-discovery Ethernet0 scope 1
!
e0
ip pim sparse-dense

e1
ip igmp join-group 224.6.6.6

After a ping from R1 to 224.6.6.6: R2#sho ip mroute IP Multicast Routing Table Flags: D - Dense, S - Sparse, B - Bidir Group, s - SSM Group, C - Connected, L - Local, P - Pruned, R - RP-bit set, F - Register flag, T - SPT-bit set, J - Join SPT, M - MSDP created entry, X - Proxy Join Timer Running, A - Candidate for MSDP Advertisement, U - URD, I - Received Source Specific Host Report, Z - Multicast Tunnel, z - MDT-data group sender, Y - Joined MDT-data group, y - Sending to MDT-data group Outgoing interface flags: H - Hardware switched, A - Assert winner Timers: Uptime/Expires Interface state: Interface, Next-Hop or VCD, State/Mode
