How To Configure Static Route On Mac

Well this is most of the time easy but useful when need and you can’t remind the command you have to use to add a static route in a Mac OS X installation. Open fist the terminal session. While adding a static route to a computer can be a great testing and troubleshooting tool, it will not enhance the actual operation of the system as the static route is only tied to the computer that the route is applied to. This method should not serve as a replacement for adding a Static Route to a system to access Layer 3 Features.

Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing protocols. Static routing can also be used in stub networks, or to provide a gateway of last resort. To configure IP Static Route.

Well this is most of the time easy but useful when need and you can’t remind the command you have to use to add a static route in a Mac OS X installation.

Open fist the terminal session. Use the following command:

sudo route -n add x.x.x.x/24 x.x.x.x

sudo route -n delete x.x.x.x/24 x.x.x.x

To view you route table on you Mac you use the following command:

netstat -nr

Add a startup item (to avoid doing the above command every reboot):

cd /System/Library/StartupItems
mkdir AddRoutes
cd AddRoutes

Create a file called AddRoutes (Note: same as the folder name).

vi AddRoutes
————————-
#!/bin/sh
# Set static routing tables
. /etc/rc.common
StartService ()
{
if [ “${ADDROUTES:=-NO-}” = “-YES-” ]; then
ConsoleMessage “Adding Static Routing Table”
sudo route -nv add 10.0.0.0/8 10.16.3.254
fi
}
StopService ()
{
return 0
}
StopService ()
{
return 0
}
RestartService ()
{
return 0
}
RunService “$1″

Then create a file StartupParameters.plist:

{
Description = “Add static routing tables”;
Provides = (”AddRoutes”);
Requires = (”Network”);
OrderPreference = “None”;
}

Then change permissions:

chmod 755 AddRoutes StartupParameters.plist

Reboot your computer. Verify with netstat -nr.

Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from a dynamic routing traffic.^[1] In many cases, static routes are manually configured by a network administrator by adding in entries into a routing table, though this may not always be the case.^[2] Unlike dynamic routing, static routes are fixed and do not change if the network is changed or reconfigured. Static routing and dynamic routing are not mutually exclusive. Both dynamic routing and static routing are usually used on a router to maximise routing efficiency and to provide backups in the event that dynamic routing information fails to be exchanged. Static routing can also be used in stub networks, or to provide a gateway of last resort.

Uses[edit]

Static routing may have the following uses:

Static routing can be used to define an exit point from a router when no other routes are available or necessary. This is called a default route.
Static routing can be used for small networks that require only one or two routes. This is often more efficient since a link is not being wasted by exchanging dynamic routing information.
Static routing is often used as a complement to dynamic routing to provide a failsafe backup in the event that a dynamic route is unavailable.
Static routing is often used to help transfer routing information from one routing protocol to another (routing redistribution).

Advantages[edit]

Static routing, if used without dynamic routing, has the following advantages:^{[citation needed]}

Static routing causes very little load on the CPU of the router, and produces no traffic to other routers.
Static routing leaves the network administrator with full control over the routing behavior of the network.
Static Routing Is very easy to configure on small networks.

Disadvantages[edit]

Static routing can have some potential disadvantages:^[3]

Human error: In many cases, static routes are manually configured. This increases the potential for input mistakes. Administrators can make mistakes and mistype in network information, or configure incorrect routing paths by mistake.
Fault tolerance: Static routing is not fault tolerant. This means that when there is a change in the network or a failure occurs between two statically defined devices, traffic will not be re-routed. As a result, the network is unusable until the failure is repaired or the static route is manually reconfigured by an administrator.
Administrative distance: Static routes typically take precedence over routes configured with a dynamic routing protocol. This means that static routes may prevent routing protocols from working as intended. A solution is to manually modify the administrative distance.^[4]
Administrative overhead: Static routes must be configured on each router in the network(s). This configuration can take a long time if there are many routers. It also means that reconfiguration can be slow and inefficient. Dynamic routing on the other hand automatically propagates routing changes, reducing the need for manual reconfiguration.

Example[edit]

How to open pgm file. To route IP traffic destined for the network 10.10.20.0/24 via the next-hop router with the IPv4 address of 192.168.100.1, the following configuration commands or steps can be used:

Linux[edit]

Fl studio for mac crack torrent. In most Linux distributions, a static route can be added using the iproute2 command. The following is typed at a terminal:-^[5]

Cisco[edit]

Enterprise-level Cisco routers are configurable using the Cisco IOS command line, rather than a web management interface.

Add a static route[edit]

The commands to add a static route are as follows:^[6]

Network configurations are not restricted to a single static route per destination:^[6]

Configuring administrative distance[edit]

The administrative distance can be manually (re)configured so that the static route can be configured as a backup route, to be used only if the dynamic route is unavailable.^[7]

Router(config)# ip route 10.10.20.0 255.255.255.0 exampleRoute 1 254

Setting the administrative distance to 254 will result in the route being used only as a backup.

Static routes allow administrators to configure routes for specific hosts or networks manually as against learning dynamically using routing protocols like RIP, EIGRP and OSPF. Static routes basically tells the Cisco IOS of which next hop router or the exit interface on the local router that the traffic for a particular host or network needs to be passed to.

To add a Static Route in cisco ios based switches and routers the following is the command syntax. This command is run from the global configuration mode.

SYNTAX:

ciscorouter(config)# ip route <IP/Network> <NETMASK> <NEXT HOP ROUTER/Interface>

For example,

Add Static route to a host using an exit interface

ciscorouter(config)# ip route 192.168.2.10 255.255.255.255 serial0/0/0

Where 192.168.1.1 is the host & serial0/0/0 is the exit interface on the router

Add Static route to a Network using a next hop router

ciscorouter(config)# ip route 192.168.1.0 255.255.255.0 192.168.100.1

Where 192.168.1.0 is the network & 192.168.100.1 is the next hop router

Add a default Route in Cisco IOS

Mac Route Delete

To Add a default route using a Gateway IP Address (called as Gateway of last resort) as a next hop router

ciscorouter(config)# ip route 0.0.0.0 0.0.0.0 10.10.10.10

If you want to use a local exit interface

ciscorouter(config)# ip route 0.0.0.0 0.0.0.0 serial0/0/1

This should help. To display the static routes on a switch or a router use the following show command

ciscorouter# show ip route static

Add Static Route For Range Of Ips

To filter the output for a specific host or network

ciscorouter# show ip route static | include 10.10.10.100
