What is exit interface in static route?


What is exit interface in static route?

A static route using an exit-interface has an Administrative Distance of 0, as opposed to the default AD of 1 for static routes. An exit-interface is only functional on a point-to-point link, as there is only one possible next-hop device.

How does a router determine exit interface?

When you configure a next-hop address, the router knows where to send the traffic to, and who to ARP for. When you configure an exit interface, the router does not know the next-hop address, and as such, it will arp for the destination IP instead of the next-hop ip.

Which type of static route that is configured on a router uses only the exit interface?

Which type of static route that is configured on a router uses only the exit interface? When only the exit interface is used, the route is a directly connected static route. When the next-hop IP address is used, the route is a recursive static route. When both are used, it is a fully specified static route.

What are static routes used for?

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.

What is the default administrative distance of a static route using an exit interface instead of a next hop IP address?

By default, a static route to the 192.168. 10.0/24 network has an administrative distance of 1. Therefore, the floating route with an administrative distance of 5 will not be placed into the routing table unless the previously entered static route to the 192.168. 10.0/24 goes down or was never entered.

What is an exit interface?

Contains the information required by the exit routines for processing at each exit point. A pointer to this structure, together with the exit point identifier, is passed to each exit function.

How do I configure 3 routers in Packet Tracer?

  1. Step 1: Assign IP Address on Router0:
  2. Step 2: Assign IP Address on Router1:
  3. Step 3: Assign IP Address on Router2:
  4. Cross Verify RIP route Configuration on Router R0 using show ip route command:
  5. Cross Verify Routing Protocol on Router R1 using Show ip protocols command:

Which two methods can be used to identify the next hop in a static route?

The floating static route is only used when the primary route is not available. this, the floating static route is configured with a higher administrative distance than the primary route. The next hop can be identified by an IP address, exit interface, or both.

What is static configuration?

Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from dynamic routing traffic. Unlike dynamic routing, static routes are fixed and do not change if the network is changed or reconfigured.

What are two advantages of static routing?

Advantages of Static Routing

  • Predictability. The path that static routing takes to the destination is very predictable.
  • Network Overheads. Unlike dynamic routing, static routing does not contain any overheads ; almost zero.
  • Configurations.
  • Resource Requirement.
  • Bandwidth.

How will a router handle static routing differently if Cisco Express Forwarding is disabled?

How will a router handle static routing differently if Cisco Express Forwarding is disabled?

  1. Serial point-to-point interfaces will require fully specified static routes to avoid routing inconsistencies.
  2. It will not perform recursive lookups.
  3. Static routes that use an exit interface will be unnecessary.

Can a static route be pointed to an exit interface?

Static default routes can be configured in two different ways. They can be pointed to take a specific exit interface or a next-hop IP can be used. If you point a static route to an Ethernet interface, the route is inserted into the routing table only when the interface is up.

How are static routes shown on a Cisco router?

There are different routes in a routing table of the router. These routes are showed with different letters. The directly connected networks are showed with C, the static routes are shoed with S on cisco routers. Static Routes are the most trustfull routes after directly connected interfaces for Cisco devices.

Can a static route point to a next hop address?

->For multipoint/Broadcast interfaces, it is more suitable to use static routes that point to a next hop address to avoid the need for resolving every destination address to its L2 address. As you have seen above it is still possible to use static routes pointing to the interface but not a scalable solution.

What is the administrative distance of a static route?

So, the administrative distance of static routes is 1. This means that, if for a destination we have both a static route and a router learned by a routing protocol, always static route is selected. The default adinistrative distance of a static route can also be changed.
