The IP route table can receive the routing paths from the following sources A directly connected destination which means there are no router hops to the destination A static IP route which is a user configured route The IP route table contains the best path to a destination. Routing entry for 2. To set a static route we need to know the some information about the network that we are trying to route to such as the IP address range and netmask the IP address of the gateway and possibly the metric. 86.

This route is called the best route. Two or more routes to the same destination with the same metric load share traffic to the destination. conf Add these lines to the end or add quot metric quot to the existing interface definitions if you 39 ve already specified a setup for the eth or wlan interfaces Dec 14 2019 This is to add a static route to the routing table. This is the cost of each route. Static routes are entries made in a routing table by non automatic means and which are fix From above output 120 3 shows 120 is the default Administrative Distance of RIP Routing Information Protocol and 3 is the metric Hop Count of RIP Routing Information Protocol for above topology. Metric. EIGRP will route the same protocols that IGRP routes IP IPX Decnet and Appletalk and use the same composite metrics as IGRP to select a best path destination. 126 RE IP Route metrics RePetE815 TechnicalUser 10 Jul 05 19 34 A challenge you 39 ll likely face is that regardless of whether either route is down the default gateway IP 39 s you 39 ll be entering are neighboring IP 39 s which will respond even when the upstream connection to the Internet is down. 1 ip route add 128. conf Add these lines to the end or add quot metric quot to the existing interface definitions if you 39 ve already specified a setup for the eth or wlan interfaces Use the ip route command without options to display the IP routing table. Routes may have more than one metric and the metrics used may be exchanged between routers or it may be entirely local to that one router. Alternatively if you instead used EIGRP you could display the equivalent in EIGRP EIGRP neighbors show ip eigrp neighbor the EIGRP topology database show ip eigrp topology and the IPv4 routing table show ip route . 4 dev eth0 proto static metric 90 You should now be able to see the result using the following command Remember that your router needs to know how to reach the next hop and in our case both routers should be directly connected This is something people often forget configuring static route for the first time. Therefore the metric of a route to a subnet that the host is directly connected to should always be zero while a route going through two gateways should have a metric of two. 101 dev eth0.
