Jul 25, 2018 · To add a new static route means to define yet another destination network as well as specify via which IP address and interface the packet should travel through in order to reach its destination. For example, let's add a static route to destination network 15.15.0.0/24 via 10.1.1.110 ip address and enp0s3 interface.
By adding a static route, a router can be told how to send or forward packets to the subnets that are not directly attached. We will demonstrate adding static routes with the help of two routers, router R1 and router R2, and three subnets 12.0.0.0, 1.0.0.0 and 2.0.0.0 . Basic configuration of R1: Yes, that's correct static routes can be of different kinds, you have a route with the next hop IP this can either be a directly connected neighbour or this next hop can be recursively resolved. It's not how you configure the static route but how the next hop gateway/IP is resolved that determines whether it's a recursive static route or not. By default, Static routes have an administrative distance (AD) of 1. ADs are used for prioritization purposes. Different routes, in a specific destination network can be assigned different weights so that one of the routes is used in favor of the other. Routes having the same weight load share the traffic. We will see in practice further on how The S represents the static route with the administrative distance of 1. The router gives priority to static routes over dynamic routes, where 0is best and 255 is worst! To verify the connectivity, Ping from PC 1 to PC 5. PC1. PC1>ping 172.16.10.2. Pinging 172.16.10.2 with 32 bytes of data: Reply from 172.16.10.2: bytes=32 time=140ms TTL=126
Static routes have a very low administrative distance of 1, this means that your router will prefer a static route over any routes that were learned through a dynamic routing protocol. If we want to use a static route as a backup route, we’ll have to change its administrative distance. This is called a floating static route.
Remove all currently configured static routes on R3 than configure a default route on R3 pointing towards R2’s Serial0/0.223 interface IP. Verify that you have IP reachability from R3’s 10.63.30.0/24 network to R1’s 10.63.10.0/24 network. Verify rather or not you can ping R1’s PPP backup interface IP address. Deleting a Static Route. Open command prompt and type. route delete ipaddress. For example if you added the below static route: route add 10.0.0.0 mask 255.0.0.0 192.168.0.1. To delete you would type. route delete 10.0.0.0. List static routes. To list all static routes setup on a computer, open command prompt, type the below command and press

To All, An interesting topic came up at work the other day. Is there a limit to the number of static routes that can be held in a Cisco router? Part of our network uses a lot of static routing for security purposes. By default static route has two AD values depending on the previous parameter. If you have used next hop neighbor IP address, then the default AD value will be 1. If you have used exit interface, then the default AD value will be 0. This parameter allows us to create multiple static routes for the same destination. Adding a static route to a different subnet that cannot be accessed through your default gateway. tl;dr To add a temporary route: ip route add 172.16.5.0/24 via 10.0.0.101 dev eth0. To make it persist system or network settings restart, create a route-ifname file for an interface through which the subnet is accessed, in this case eth0: Oct 14, 2004 · A static route to Null0 is a normal static route, except that it points to the Null0 interface, which is a virtual IOS interface. Refer to the IP Routing Protocols Commands: I section of Cisco IOS IP Command Reference, Volume 2 of 4: Routing Protocols, Release 12.3 for more information about the ip route command.
