Enhanced Interior Gateway protocol (EIGRP), Open Short Path First (OSPF), and Boarder Gateway Protocol (BGP), are the most current routing protocols in Networks atmosphere. Since they have become increasingly complex, due to the fast growth of the Internet, it is often to find issues usually associated with troubleshooting such routing ...

A routing protocol enables one router to tell all the other routers to which it is connected about the networks that it can reach. OSPF, EIGRP, ISIS, and BGP are examples of routing protocols. Routed protocols are the traffic that routers direct from source to destination. IP, HTTP, SSH, and SIP are examples of routed protocols. Hope that helps.

This is what redistribution is for. It basically allows you to distribute routes from a foreign routing protocol into another protocol that will then advertise to neighbor devices running the same protocol. Think of it as almost a routing protocol translator. Now for redistrubtion to work, you will need at least one device that runs both protocols.

So if the routing table has 10.0.0.0 / 8 prefix as well as 10.17.0.0 / 16, route lookup will select 10.17.0.0 / 16 route for any packets destined to 10.17.x.x network. If the prefix length is the same and the route is learnt via two routing protocols, the Administrative Distance AD parameter kicks in as the deciding factor.

Application Layer Routing protocol. RIP. BGP . Network Layer Routing Protocol. EIGRP. OSPF . Layer 2 (i believe) IS-IS . The reasoning for this is that RIP and BGP ride on top of TCP/UDP whereas EIGRP and OSPF both have their own transport protocols 88 and 89. Also, IS-IS is encapsulated directly inside a Layer 2 header i think from memory. Cheers

2020年6月10日 · 3.3 Describe how a routing table is populated by different routing information sources. 3.3.a Admin distance; 3.4 Configure, verify, and troubleshoot inter-VLAN routing. 3.4.a Router on a stick; 3.4.b SVI; 3.5 Compare and contrast static routing and dynamic routing. 3.6 Compare and contrast distance vector and link state routing protocols

Classful routing protocols: RIPv1, IGRP. 1. Do not send masks in routing updates. At all. (Cannot advertise subnetted networks like 192.200.1.0 /30) 2. Do not support VLSM . 3. Do not support manual route summarization . Classless routing protocols: RIPv2, EIGRP, OSPF, IS-IS . 1. Send masks in routing updates. 2. Support VLSM . 3. Support ...

OSPF is a link-state routing protocols. OSPF routers in the same area build topology databases based on link-state advertisements(LSA) that are propagated throughout the area. After generating the topology database, the OSPF router will run the SPF algorithm to compute the best route and store in the routing table.

This is a list of protocols that we encounter in CCNA level. i have listed also protocol number for some protocols. I have included port numbers of some application level protocols. I hope this will help you. Vipin

Static routing is most commonly used in VPN 0, but BGP and OSPF dynamic routing protocols are also supported. Management VPN 512 (aka Mgmt-Intf VRF) : VPN 512 is the other reserved VPN used for out-of-band management.
