Do static routes have the highest priority?

To select the optimal route, each routing protocol and static route are configured with priorities, and the route with the highest priority becomes the optimal route. Table 2-1 lists routing protocols and their default priorities.

Does order matter in route table?

The routing table is usually applied in order from “most specific” to “least specific”. A destination of 0.0. 0.0 with a netmask of 0.0. 0.0 , i.e. your default route, is the least specific possible and so will always be applied last.

What is the default priority of direct routes?

The preference of a direct route is always 0 and cannot be changed. You can configure a preference for each static route and each dynamic routing protocol. The following table lists the route types and default preferences. The smaller the value, the higher the preference.

Which route is preferred static or default?

Hence static routes are given more preference than any other route when configured on a router. Default Routes: The default routes are used when an IP packet does not find a route to its destination address from the routing table. Default route is a special case of static routing.

How does a router choose the best path?

The best path is selected by a routing protocol based on the value or metric it uses to determine the distance to reach a network. A metric is the quantitative value used to measure the distance to a given network. The best path to a network is the path with the lowest metric.

What is the order of preference for a route to be chosen by a router from the routing table?

A router evaluates routes in the following order.

  • Prefix Length – The longest-matching route is preferred first.
  • Administrative Distance – In the event there are multiple routes to a destination with the same prefix length, the route learned by the protocol with the lowest administrative distance is preferred.

What is target and destination in route table?

Each route has a destination and target field. Destination field specifies the pattern that a request must match with its destination address (IP or CIDR range). Target field specifies where such a request should be routed.

Which routing protocol does a router prefer?

Interior Gateway Protocol (IGP) It is widely used by routers to exchange routing data within an autonomous system. This type of routing protocol is the best for larger network size as it broadcasts after every 90 seconds, and it has a maximum hop count of 255. It helps you to sustain larger networks compared to RIP.

Where should we use default routing?

Default routing is used only in stub networks. Stub are the networks that have only one output interface and everything going through these networks has to cross the single exit point.

What is the difference between default route and static route?

Static Routing – This is the method by which an administrator manually adds routes to the routing table of a router. This is a method for small networks but it is not scalable for larger networks. Default Routing – This is the method where all routers are configured to send all packets towards a single router.

Which type of routing is preferred?

Route 2 is preferred because it has a higher LocalPref value and a lower Preference2 value. You can also mark route preferences with additional route tiebreaker information by specifying a color and a tiebreaker color (by including the color and the tiebreaker color2 statements in the configuration).

What is route preference?

Routing protocols, including static and direct routing, each by default have a preference. If they find multiple routes to the same destination, the router selects the route with the highest preference as the optimal route. The preference of a direct route is always 0 and cannot be changed.
