3560E-24TD and igmp in a layer 2 environment

[mulhollandm]

folks

i have 3560e which doesn't appear to be passing igmp traffic to the upstream router

PC1 ----------- ASA ------------ PC2--------- 3560e ----------- 3825 -------------------- WAN --------------------- Router ------------- Server

My ASA runs SMR, has an igmp forward interface outside command on the inside and has a trunk port to the 3560e (Vlans 32 & 48)

PC2 is a test pc on the 3560e on vlan32

3825 is my ISPs router on vlan32

- if i try to access the stream from PC2 it works

- if i try to access the stream from PC1, i see the igmp join leave my ASA onto the 3560E (i've captured on the 3560e's link to the ASA)

  i've also captured on the ASA and i can see the igmp packet leave the outside interface

  but the join doesn't reach the 3825 (i've captured on the 3560e port facing the router and there is no join being forwarded)

the switch is running in layer 2, 12.2(35r)SE1

switch#sh ip igmp snooping querier
Vlan      IP Address               IGMP Version   Port
-------------------------------------------------------------

switch#

Global IGMP Snooping configuration:
-------------------------------------------
IGMP snooping                : Enabled
IGMPv3 snooping (minimal)    : Enabled
Report suppression           : Enabled
TCN solicit query            : Disabled
TCN flood query count        : 2
Robustness variable          : 2
Last member query count      : 2
Last member query interval   : 1000

anyone any ideas?

thanks to anyone taking the time to read this or to reply

i've configured the command

ip igmp snooping vlan 32 mrouter int gi0/21

the ISP router is on gi0/21

the ASA is on gi0/7

switch#sh ip igmp snooping groups vlan 32
Vlan      Group                    Type        Version     Port List
-----------------------------------------------------------------------
32        239.192.61.10            igmp        v2          Gi0/7, Gi0/21
32        239.255.255.250          igmp        v2          Gi0/7, Gi0/21

still no traffic hitting the asa external interface

hi, I'm  a bit late here, but was researching IGMP on ASA and found this. offhand, it seems like there is a problem with the trunk link passing the IGMP join to the 3560. perhaps the 3560 doesn't process the JOIN and install the group address on the correct vlan?

If that doesnt work, try setting the pim RP value (3825 router address) in the ASA.

pim rp-address W.X.Y.Z
