This example is for OSPF ): Router (config-router) # redistribute protocol [process-id] [metric-value] [metric-type-value] [subnets] In this command: ◎ Protocol: Specifies the source route protocol for Route redistribution on the vro.

How to configure vro redistribution

Before route redistribution, you must first: 1) decide where to add a new protocol. 2) determine the border router ASBR of the autonomous system ). 3) decide which protocol is at the core and which is at the boundary. 4) determines the route redistribution direction. You can use the following command to reallocate route updates. This example is for OSPF ): Router (config-router) # redistribute protocol [process-id] [metric-value] [metric-type-value] [subnets] In this command: ◆ Protocol:

between nodes. LDP signaling and tag binding information are transmitted only between neighboring MPLS nodes. Standard routing protocols need to be run between LSR or between LSR and LER to obtain topology information. With this information, LSR can clearly select the next hop of the packet and establish a specific tag exchange path LSP ). MPLS uses the control drive model, that is, it initializes the allocation and forwarding of tag binding information used for creating LSP Based on the topolo

How to sniff the Exchange network and the principles of ARP con-arp interpretation

sniff (typically a sniffer can eavesdrop on packets flowing through the network).ARP Spoofing (ARP spoofing)The ARP protocol does not receive ARP replies more than just sending an ARP request. When the computer receives an ARP reply packet, the local ARP cache isis updated to store the IP and MAC addresses in the answer in the ARP cache. So. In the above if the network, B sends a self-forged ARP to a shouldFor. The data in this answer is the sender I

Network Fundamentals-Static routing + dynamic routing

Description: After the use of IP to identify each network node, if the two nodes separated by multiple network nodes to communicate, need to "man-in-the-middle" strings, the step by step notice a node data, to go to the end of the node step-by-step how to go.Static routing: Manually configure static routing information that can be forwarded using a leased line interface or a next-hop IP address based on the routing information when forwarding packets with matching destination addresses.Advantage

In this function, the current task execution is suspended. Also see if the Task Scheduler table has a priority-ready task. If the current task runs, call Osschedlock () to lock the scheduler so that the current task is suspended when you call ostimedly ().
