+ The configuration is complex, especially with large network. + Each site requires a static public IP address if the environment between them are public (like the Internet). This also increases latency for time-sensitive applications such as VoIP, video conference… + When a spoke wants to communicate with another Spoke, it must go through the Hub which increases the traffic passing through the Hub, increase CPU and memory usage on Hub and can create bottle-neck problem. Some new labs for CCNP TSHOOT v2 have been added. Some more screenshots are available here.

The README.pdf contains all necessary information about how to use these labs. But there are some disadvantages with this topology: Those and many more are available now as an open source git project on GitLab. In this Hub-and-Spoke topology, each Branch can access some resources on the HeadQuarter. The router at the HeadQuarter undertakes the role of a Hub while branch routers take the role of Spokes. With the development in IT field we also add more offers and. You can talk online with the professionals for clearing the concepts ccnp tshoot 300-135 topology questions. The main enterprise resources are located in the HeadQuarter. There are ccnp tshoot 300-135 vce coupon cards for which you can take more facilities for your Troubleshooting and Maintaining Cisco IP Networks (TSHOOT) exam preparation. One of the most popular network topology in practical nowadays is shown below with one HeadQuarter connecting to branch offices at some locations. Examples include protocols such as Telnet, SSH, SNMP, NTP… Management plane packets: packets that are used to manage the network. Examples include packets of routing protocols like OSPF, EIGRP, BGP or some other non-routing protocols like CDP…Ĥ. Control plane packets are always handled by the CPU in the network device route processor. Control plane packets: Network device generated or received packets that are used for the creation and operation of the network itself. “Punt” is often used to describe the action of moving a packet from the fast path (CEF) to the route processor for handling.ģ. Examples of high-touch handling include such functions as GRE encapsulation, QoS, MPLS VPNs, and SSL/IPsec encryption/decryption…Īs we see in the picture below, some traffic of the services plane is “punted” (or “pulled”) to handle in the CPU while other is treated by CEF only. Services plane packets: a special case of data plane packets, services plane packets are also user-generated packets that are also forwarded by network devices to other hosts, but that require high-touch handling by the network device (above and beyond normal, destination IP address-based forwarding) to forward the packet. Data plane packets: user-generated packets that are always forwarded by network devices to other end-station devices.Ģ. IS-IS, another LSR-based protocol, is more common in large service provider networks.The IP traffic managed by a device can be divided into four distinct, logical groups:ġ.
OSPF is a widely used IGP in large enterprise networks. OSPF supports the Classless Inter-Domain Routing (CIDR) addressing model. The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 (2008). It is defined as OSPF Version 2 in RFC 2328 (1998) for IPv4. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS).
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. One of the major reasons for this was the change to classless IPv4 addresses in the Internet Protocol, which IGRP could not support. Unlike other well known routing protocols, such as RIP, EIGRP only sends incremental updates, reducing the workload on the router and the amount of data that needs to be transmitted.ĮIGRP replaced the Interior Gateway Routing Protocol (IGRP) in 1993. Just failed twice with 711 and 820, on the first attempt I waist my time becuase i was trying on bgp lap to find the issue, on the second one in L2 Ticket, the access port connect to client was shut down and i found after excute on ASW1 show run, also it has Vlan access-list so becuase there is no related answer on ASW1, i decide to chose Vlan access-map. Partial functionality of EIGRP was converted to an open standard in 2013 and was published with informational status as RFC 7868 in 2016.ĮIGRP is used on a router to share routes with other routers within the same autonomous system.
The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.
