You must allow for multicast broadcasting to take place in order for ehcache to sync successfully between servers on a Linux machine. Opening datagram socket.OK. This code example for Multicast, uses RDMA-CM and VPI (and hence can be run both over IB and over LLE). Revert to WebExample: Configuring the Multicast Forwarding Cache When a routing device receives multicast traffic, it places the (S,G) route information in the multicast forwarding cache, inet.1. As IP multicast groups are 28 bits long, the mapping can not be one-to-one. TTL of 0 are not transmitted on any sub-network. The PIM DR is the PIM speaker with the highest IP address on the segment. where mreq contains the same values used to add the membership. Ive tried the following commands: sudo ip maddr add 226.0.0.59 dev eth0 sudo route add 226.0.0.59 dev eth0 Unfortunately, when I ping the multicast ip address it doesnt work. both sender/receiver assign to a local ip 203.106.93.94 and bound to group ip 226.1.1.1. why do i have to bound to this local 203.106.93.94?? an interface supports multicasting, fetch the interface flags with the SIOCGIFFLAGS ioctl In the above example, the ip addr show command displays the network information, including the IP address, the netmask, broadcast, etc. 2.
