regarding "ip multicast boundary <xyz> in" posted 04/07/2008
[Chronological Index] [Thread Index] [Top] [Date Prev][Date Next] [Thread Prev][Thread Next]


Hello All,

I am trying to get "multicast boundary <> in" working and I need a few
clarifications.
Topology:     R0--------R1--------R2(fa0/0)--------(fa1/1)R3

I have pim sparse mode enabled on all the connected interfaces. with R1 as
the RP
I have clients configured on R0(ip igmp join-group for 236.1.1.1 and
226.1.1.1)

Now I have configured "ip multicast boundary 27 in"   on R2's fa0/0 and I am
trying to allow only group 236.1.1.1 from R3.

My  access-list for 27 is like this
    permit 224.0.1.39
    permit 224.0.1.40
    permit 236.1.1.1
    deny   any

I see that I am able to ping to 236.1.1.1 and also to 226.1.1.1, I was
expecting only 236.1.1.1 to be permitted access(RPF suceess).

Could you please let me know what I am missing here.

Regards,
Arun
