What is a characteristic of static routes?
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.
What is a null0 static route?
The purpose of configuring a static summary route to null0 is to make sure that traffic will be dropped on the local router if a more specific route doesn’t exist.
What are the A advantages and B disadvantages of static routing?
Table 3-2 Static Routing Advantages and Disadvantages
|Very secure. No advertisements are sent, unlike with dynamic routing protocols.||Configuration complexity increases dramatically as the network grows. Managing the static configurations in large networks can become time consuming.|
What are the two advantages of static routing over dynamic routing?
It provides easy routing table maintenance in networks. Static routing consumes less bandwidth when compared to dynamic routing as no CPU cycles are-used in route calculation and communication. Because static routes do not advertise their route over the network, it results in better network security.
What is Null0 in BGP?
Using the null0 route gets the summary of the addresses that match your BGP network statement into the routing table. Once you’ve done this you can enter the network statement for 203.0. 113.0/24 in BGP, and BGP will advertise that network.
What are the types of static route?
The following types of IPv4 and IPv6 static routes will be discussed:
- Standard static route.
- Default static route.
- Summary static route.
- Floating static route.
What are the advantages of static route?
Advantages of static routing Static routing consumes less bandwidth when compared to dynamic routing as no CPU cycles are-used in route calculation and communication. Because static routes do not advertise their route over the network, it results in better network security.
What is the main advantage of static routing over dynamic routing?
What is a static route to null0?
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.
Why do we use NULL 0 in BGP?
One of the reasons to use null 0 is to promote stability in the BGP network. In BGP networking stability of routes is of high importance and a flapping of routes in BGP may have even more impact than flapping of routes in Interior Protocols.
What does IP route 10 0 null0 mean?
ip route 10.0.0.0 255.0.0.0 null0 then packet destain for the network 10.0.0.0 will point to the null 0 it means that the packet destain for the network 10.0.0.0 will discarded as they are pointing to the null interface 0…some time using this you can prevent the loops in routing anivronment… 06-12-2006 06:32 AM 06-12-2006 06:32 AM
What is the null0 interface used for?
The Null interface is typically used for preventing routing loops. Enhanced Interior Gateway Routing Protocol (EIGRP), for instance, always creates a route to the Null0 interface when it summarizes a group of routes. Whenever a routing protocol summarizes, this means that the router might receive traffic for any IP address within that summary.
