Hi, When using a routing protocol suite like Zebra or GateD, if we bring up a routing protocol like RIP or OSPF that uses multicast address, the multicast address is added to the interfaces on which these protocols are configured. If you do "ip maddr", you see that the interfaces have the multicast address attached to them. My question is, that does netlink communicate these updates to the user applications listening on the netlink socket? i.e. if a user application is listening to the netlink socket, will it get a message that interface eth4 should now accept packets with DA 224.0.0.9? Thanks. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
