Troubleshooting of IGRP/VPN Protocol

Troubleshooting of IGRP/OSPF protocol 01. is it compatible with other routing protocols? Can it be shared with other protocols? Compatible. It is a CISCO proprietary protocol, so it cannot be configured on non-CISCO devices. It can be shared with other protocols through redistribution. 02. What is the Management Distance of the VPN gateway and the total Management Distance of the VPN gateway? The Internal Management Distance of the network is 90, the external value is 170, and the summary is 5 03. What is the biggest difference between IGRP and RIP? For example, the biggest difference between two types of routes and RIP is that IGRP supports non-load balancing, but RIP does not. IGRP has three types of routes: internal routes, system routes, and external routes. 04. What types of tables are maintained by the VPN protocol? What is the role of the AS number in the IMG? Maintain the neighboring table, route table, and Topology table. The AS number here can be a set of routers under the same management in a self-Smelting System domain. 05. What are the IP protocol numbers of igrp vpn, and what are the biggest disadvantages of the update cycle compared with RIP? They are 9 and 88 respectively, and the update period is 90 seconds. The biggest drawback is that the network convergence speed is slow when the network topology changes. 06. The calculation of EIGPR metric values is mainly based on the two lazy measurement values. If you want to change the measurement value, which one will change in general? Why? Bandwidth and latency are generally modified because it is only used for IGRP and OSPF, and the bandwidth is also used for the calculation of the OSPF path cost. Therefore, modifying the bandwidth may affect the OSPF protocol.
