Hello fourm, Question on how to disable IGMP on a router interface - in this case Gig 0/2 on an ISR G2.   Rotuer is an ISR G2 running 15.2(1)T code and I want to disable all multicast processing on the interface. Here is what I see: c2911-rtr#show ip igmp interface gigabitEthernet 0/2 GigabitEthernet0/2 is up, line protocol is up   Internet address is 99.165.56.16/22   IGMP is enabled on interface   Current IGMP host version is 2   Current IGMP router version is 2   IGMP query interval is 60 seconds   IGMP configured query interval is 60 seconds   IGMP querier timeout is 120 seconds   IGMP configured querier timeout is 120 seconds   IGMP max query response time is 10 seconds   Last member query count is 2   Last member query response interval is 1000 ms   Inbound IGMP access group is not set   IGMP activity: 1 joins, 0 leaves   Multicast routing is disabled on interface   Multicast TTL threshold is 0   Multicast groups joined by this system (number of users):       224.0.1.41(1) c2911-rtr# c2911-rtr#show ip interface gigabitEthernet 0/2 GigabitEthernet0/2 is up, line protocol is up   Internet address is 91.165.56.16/22   Broadcast address is 255.255.255.255   Address determined by DHCP   MTU is 1500 bytes   Helper address is not set   Directed broadcast forwarding is disabled   Multicast reserved groups joined: 224.0.0.1 224.0.0.2 224.0.0.22   Outgoing access list is not set   Inbound  access list is 105   Proxy ARP is disabled   Local Proxy ARP is disabled   Security level is default   Split horizon is enabled   ICMP redirects are never sent   ICMP unreachables are always sent   ICMP mask replies are never sent   IP fast switching is enabled   IP fast switching on the same interface is enabled   IP Flow switching is disabled   IP CEF switching is enabled   IP CEF switching turbo vector   IP multicast fast switching is enabled   IP multicast distributed fast switching is disabled   IP route-cache flags are Fast, CEF   Router Discovery is disabled   IP output packet accounting is disabled   IP access violation accounting is disabled   TCP/IP header compression is disabled   RTP/IP header compression is disabled   Policy routing is disabled   Network address translation is enabled, interface in domain outside   BGP Policy Mapping is disabled   Input features: Common Flow Table, Stateful Inspection, Virtual Fragment Reassembly, Access List, Virtual Fragment Reassembly After IPSec Decryption, NAT Outside, MCI Check   Output features: Post-routing NAT Outside, Common Flow Table, Stateful Inspection, NAT ALG proxy   WCCP Redirect outbound is disabled   WCCP Redirect inbound is disabled   WCCP Redirect exclude is disabled c2911-rtr# Multicast is disabled: c2911-rtr#show ip multicast   Multicast Routing: disabled   Multicast Multipath: disabled   Multicast Route limit: No limit   Multicast Fallback group mode: Dense   Number of multicast boundaries configured with filter-autorp option: 0 c2911-rtr# c2911-rtr#show ip igmp snooping Global IGMP Snooping configuration: ----------------------------------- IGMP snooping              : Disabled IGMPv3 snooping            : Disabled Report suppression         : Disabled TCN solicit query          : Disabled Last Member Query Interval : 1000 . . . . c2911-rtr#show ip igmp membership Flags: A  - aggregate, T - tracked        L  - Local, S - static, V - virtual, R - Reported through v3        I - v3lite, U - Urd, M - SSM (S,G) channel        1,2,3 - The version of IGMP, the group is in Channel/Group-Flags:        / - Filtering entry (Exclude mode (S,G), Include mode (G)) Reporter:        <mac-or-ip-address> - last reporter if group is not explicitly tracked        <n>/<m>      - <n> reporter in include mode, <m> reporter in exclude Channel/Group                  Reporter        Uptime   Exp.  Flags  Interface *,239.192.152.143              192.168.1.97    03:42:36 02:15 2A     BV1 *,239.255.255.253              192.168.1.239   6d00h    02:20 2A     BV1 *,239.255.255.250              192.168.1.201   6d00h    02:24 2A     BV1 *,235.0.0.1                    192.168.1.4     6d00h    02:17 2A     BV1 *,224.0.1.40                   192.168.1.254   6d00h    02:16 2LA    IS0/0 *,224.0.1.41                   192.168.1.254   6d00h    02:16 2LA    SM1/0 *,224.0.1.41                   99.165.56.16    6d00h    stop  2LA    Gi0/2 *,224.0.1.41                   192.168.1.254   6d00h    02:19 2LA    IS0/0 *,224.0.1.41                   0.0.0.0         6d00h    never 2LA    Em0/0 c2911-rtr# c2911-rtr# Here is  how I have the interface configued: ! interface GigabitEthernet0/2 ip address dhcp client-id GigabitEthernet0/2 hostname c2911-rtr ip access-group 105 in no ip redirects no ip proxy-arp ip nbar protocol-discovery no ip mfib forwarding input no ip mfib forwarding output ip nat outside ip virtual-reassembly in ip route-cache same-interface load-interval 30 duplex auto speed auto no cdp enable no mop enabled ! any ideas? ...
