[Bridge] how to disable multicast_router in bridge? and get rid of the LLDP messages
Hi All, I created 3 bridges and inter-connected them with veth links. No external nodes are connected to this n/w and STP is disabled and hence expected links to be silent. [Yes, I dont want STP, even though this looped topo] I got ipv6 multicast LLDPs and hence disabled ipv6 through sysfs for all nodes. After that I am getting 0.000000 86:79:7b:e4:8c:9f -> LLDP_Multicast LLDP 222 Chassis Id e8:03:9a:3b:1c:28 Port Id = 86:79:7b:e4:8c:9f TTL = 120 0.000031 2a:b3:bc:44:7a:44 -> LLDP_Multicast LLDP 221 Chassis Id e8:03:9a:3b:1c:28 Port Id = 2a:b3:bc:44:7a:44 TTL = 120 which are LLDP nearest messages which I want to get rid off. I was suspecting it as due to multicast_router being enabled in bridge by default and hence want to disable. I able to disable multicast_snooping (file is written) but could not multicast_router. Manual write with vi editor fails with sysfs sync failure. Please let me know how I could stop these messages. Reference: http://www.linuxfoundation.org/collaborate/workgroups/networking/bridge#Snooping I am not able to set the value in "multicast_router" file to "0" while I can do that for "multicast_snooping" system details : 3.2.0-26-generic-pae #41-Ubuntu SMP Thu Jun 14 16:45:14 UTC 2012 i686 i686 i386 GNU/Linux brctl -V bridge-utils, 1.5 Please let me know if any more information is needed.
