Explain in detail unified forwarding algorithm
Answers
Explanation:
On QFX5100, EX4600, QFX5200 and OCX1100 switches, you can control the allocation of forwarding table memory available to store the following:
MAC addresses—In a Layer 2 environment, the switch learns new MAC addresses and stores them in a MAC address table
Layer 3 host entries–In a Layer 2 and Layer 3 environment, the switch learns which IP addresses are mapped to which MAC addresses; these key-value pairs are stored in the Layer 3 host table.
Longest prefix match (LPM) table entries—In a Layer 3 environment, the switch has a routing table and the most specific route has an entry in the forwarding table to associate a prefix or netmask to a next hop. Note, however, that all IPv4 /32 prefixes and IPv6 /128 prefixes are stored in the Layer 3 host table.
HI friend
IP routing is the field of routing methodologies of Internet Protocol (IP) packets within and across IP networks. This involves not only protocols and technologies, but includes the policies of the worldwide organization and configuration of Internet infrastructure. In each IP network node, IP routing involves the determination of a suitable path for a network packet from a source to its destination in an IP network. The process uses static configuration rules or dynamically obtained status information to select specific packet forwarding methods to direct traffic to the next available intermediate network node one hop closer to the desired final destination, a total path potentially spanning multiple computer networks
