What command are we using for checking the existing routes on a router?
The netstat -r command displays the current routing information contained in the routing tables.
What two router commands would an administrator use to determine if the exit interface was up and the next hop address is available?
The network administrator could use the show ip interface brief command to verify that the exit interface or the interface connected to the next hop address is up and up. The ping command can be used to see if the next hop address is reachable. The show ip route command displays the routing table.
What command allows you to check the route taken by packets across an ipv6 network?
In computing, traceroute and tracert are computer network diagnostic commands for displaying possible routes (paths) and measuring transit delays of packets across an Internet Protocol (IP) network.
Which command is used on Cisco routers to check all the routes?
show ip route command
The show ip route command is used to show the router’s routing table. This is the list of all networks that the router can reach, their metric (the router’s preference for them), and how to get there. This command can be abbreviated sh ip ro and can have parameters after it, like sh ip ro ospf for all OSPF routes.
What is use of RT command?
route command in Linux is used when you want to work with the IP/kernel routing table. It is mainly used to set up static routes to specific hosts or networks via an interface. It is used for showing or update the IP/kernel routing table.
What is the route command used for?
The route command allows you to make manual entries into the network routing tables. The route command distinguishes between routes to hosts and routes to networks by interpreting the network address of the Destination variable, which can be specified either by symbolic name or numeric address.
What does the five at the end of the command signify?
The 5 at the end of the command signifies administrative distance. This value is added to floating static routes or routes that only appear in the routing table when the preferred route has gone down. The 5 at the end of the command signifies administrative distance configured for the static route.
What command would be used to configure a static route on R1?
To configure an IPv6 static route, use the ipv6 route command followed by the destination network. Then add either the IP address of the adjacent router or the interface R1 will use to transmit a packet to the 2001:db8:1:4::/64 network. Refer to the exhibit.
What is traceroute command used for?
Traceroute is a command that runs tools used for network diagnostics. These tools trace the paths data packets take from their source to their destinations, allowing administrators to better resolve connectivity issues. On a Windows machine, this command is called tracert; on Linux and Mac, it’s called traceroute.
Does Cisco router have WR command?
By copying the configuration into flash, it will be saved when the router is powered off and restarted. This command can only be used in Privileged EXEC mode. A shortcut for this command is wr (which is short for write memory).
What is show command in Cisco?
Cisco routers run an operating system, called IOS. Like any operating system, IOS includes a command language to enable equipment owners to retrieve information and change the device’s settings. One of the most powerful commands in IOS is show. This command retrieves information.
How to see the details of a router interface?
To view the detail of specific interface you can use the following command. For example to view the detail of serial 0/0/0 interface on Router0 we will use following command Output of this command provides several details about interface including its status, encapsulation, interface type, MTU, last input and output packet etc.
What is the result of a Cisco router issuing the command IP DHCP excluded-address?
What is the result of a network technician issuing the command ip dhcp excluded-address 10.0.15.1 10.0.15.15 on a Cisco router? The Cisco router will exclude only the 10.0.15.1 and 10.0.15.15 IP addresses from being leased to DHCP clients. The Cisco router will automatically create a DHCP pool using a /28 mask.
What’s the administrative distance of a router R1?
Router R1 is using an EIGRP route which has an administrative distance of 90 to reach the 10.10.0.0/16 network. To be a backup route the floating static route must have an administrative distance greater than 90 and have a next hop address corresponding to the serial interface IP address of Branch1.
What happens when static route is not entered in routing table?
In a recursive static route, only the next-hop IPv6 address is specified. As a consequence, the router must perform a recursive route table lookup to find an exit interface associated with the network of the IPv6 address. A network administrator notices that a correctly entered static route is not in the routing table.
