Additionally, the routers will use reverse-path forwarding to ensure that there are no loops for packet forwarding among routers that wish to receive multicast packets. When a data packet is received on a non-RPF interface, a mechanism is required to prevent loops. If the non-RPF interface is a LAN, an Assert message is sent.
It then forwards the packet along to the next router in the path, which swaps the packet's outer label for another label, and forwards it to the next router. The last router in the path removes the label from the packet and forwards the packet based on the header of its next layer, for example IPv4. Due to the forwarding of packets through an ...
The All Routers multicast group addresses all routers on the same network segment. No 224.0.0.4 This address is used in the Distance Vector Multicast Routing Protocol (DVMRP) to address multicast routers. No 224.0.0.5 The Open Shortest Path First (OSPF) All OSPF Routers address is used to send Hello packets to all OSPF routers on a network ...
The label edge routers at the edges of an MPLS cloud map between the end-to-end identifier, such as an IP address, and a link-local label. At each MPLS hop, there is a forwarding table that tells the label-switched router which outgoing interface is to receive the MPLS packet, and what label to use when sending the packet out that interface.
Problem with the bootp request is that the request is broadcast. A broadcast IP datagram cannot pass through any router. The router discards this packet. To solve this problem, there is a need for an intermediary (relay). One of the host or router can be configured at application layer to operate as relay agent.
Port Control Protocol (PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering.
The primary function of a router is to forward a packet toward its destination network, which is the destination IP address of the packet. To do this, a router needs to search the routing information stored in its routing table. The routing table contains network/next hop associations. These associations tell a router that a particular ...
Packet Decoding is the capture and analysis of the network traffic generated during Packet Play. In order to determine the targeted network's response to the scenario created by Packet Play, the response must be captured by a packet analyzer and decoded according to the appropriate specifications. Depending on the packets sent, a desired ...
