2 Experiment 2: Implementing Cisco VxLAN & centralized gateway based on Multicast
1. Description Same as the previous article “1 Experiment 1: Implementing Cisco VxLAN & centralized gateway based on static Ingress Replication”, implementing VxLAN based on Multicast also uses traffic-driven MAC address flooding learning and VTEP neighbor establishment. , there is no control level; Unlike implementing VxLAN based on Static Ingress Replication, implementing VxLAN based on […]

Embedded Development Plan-30-Network Programming—-Multipoint Communication–Unicast–Broadcast–Multicast
Sixty-six, multipoint communication 66.1 Network attribute related functions getsockopt setsockopt Function: Get/set network properties; prototype: #include <sys/types.h> /* See NOTES */ #include <sys/socket.h> int getsockopt(int sockfd, int level, int optname, void *optval, socklen_t *optlen); int setsockopt(int sockfd, int level, int optname, const void *optval, socklen_t optlen); Parameters: int sockfd: Specifies which socket’s network properties are […]
multicast-3 multicast loop prevention principle-RPF
Multicast ring prevention principles 1 The main difference between unicast routing and multicast routing Unicast routing determines where the data packet should go: destination Multicast routing cares about where the data packets come from. (The first action is to verify first, check the source, then check the destination address, and then forward) 2 Unicast routing […]
IPSG technology and IP multicast
1, IPSG technology overview Experiment: DHCP snooping + IPSG Topology: Requirements: 1. Implement PC1 and PC2 to dynamically obtain IP addresses. 2. Configure DHCP snooping on SW2 to achieve DHCP server security. 3. Perform IPSG on the interface connecting PC 1 and PC2 to prevent the terminal from changing its address and committing fraud. 4. […]
Network programming four: UDP broadcast + UDP multicast
1. Broadcast 1. What is broadcast Unicast: A method of sending data packets with only one receiver Broadcast: sent to all hosts in the LAN at the same time 2. Features Only user datagram sockets (using UDP protocol) can broadcast. 3. Broadcast address Taking the 192.168.14.0 network segment as an example: ***.***.***.255 represents the broadcast […]

2. Broadcasting 1. Broadcasting characteristics Multipoint communication network-wide broadcast: 255.255.255.255, which can easily cause network storms. Subnet broadcast: x.x.x.255 only allows datagram socket operations /*Set the network to allow broadcasts*/ int val = 1 setsockopt(fd, SOL_SOCKET, SO_BROADCAST, & amp ;val, sizeof(int)); 2. Broadcast sender process Create a datagram (udp) socket Set socket properties to allow […]
