RIPv2 (Routing Information Protocol) - Cisco Community 2) In RIPv1, subnet masks are NOT included in the routing update and In RIPv2 Subnet masks are included in the routing update. 3) RIPv2 multicasts the entire routing table to all adjacent routers at the address, as opposed to RIPv1 which uses broadcast ( Unicast addressing is still allowed for special applications. What is a Routing Table? - Computer Hope 2017-4-26 · The routing table contains a list of specific routing destinations. When the router receives a packet of data, it references the routing table to know where to send that data. The routing table may also contain information on how far each destination is from the router. In essence, a routing table is a map for the router.

OpenWrt Project: IPTV / UDP multicast

OpenWrt Project: IPTV / UDP multicast iptables -t mangle -A PREROUTING -i eth0 -d -p udp -j TTL --ttl-set 2. This will cause multicast UDP packets to have a TTL of 2 prior to being routed by OpenWrt allowing them to be sent out the LAN interface with TTL=1. You can increase the value further if you need to route the packets further across sub-networks in your personal iptables命令_Linux iptables 命令用法详解:Linux …

Using the route Command. Using the route command displays or modifies the computer's routing table. For a typical computer that has a single network interface and is connected to a local area network (LAN) that has a router, the routing table is pretty simple and isn't often the source of network problems.

Router Operation (1.3) > Routing Concepts | Cisco Press Routing Table Sources ( On a Cisco router, the show ip route command is used to display the IPv4 routing table of a router. A router provides additional route information, including how the route was learned, how long the route has been in the table, and which specific interface to use to get to a predefined destination.
