Hi Rene,
I do not understand based on the last output shown below
(Now we see FastEthenet0/0 as the Bidir-Upstream interface and FastEthernet0/1 in the outgoing list. This is something different than what you have seen before right?)
Isn’t your earlier output already showing FastEthenet0/0 as the Bidir-Upstream interface and FastEthernet0/1 in the outgoing list?
R3#show ip mroute 239.1.1.1
(*, 239.1.1.1), 00:09:39/00:03:10, RP 1.1.1.1, flags: BC
**Bidir-Upstream: FastEthernet0/0**, RPF nbr 192.168.13.1
**Outgoing interface list:**
**FastEthernet0/0, Bidir-Upstream/Sparse**, 00:09:39/00:00:00
**FastEthernet0/1, Forward/Sparse**, 00:09:39/00:02:42
Thanks,
Kent
