Why would a summarized static route be configured on a router?
to reduce the size of the routing table
Refer to the exhibit. Which set of commands will configure static routes that will allow the Park and the Alta routers to a) forward packets to each LAN and b) direct all other traffic to the Internet?
Park(config)# ip route 0.0.0.0 0.0.0.0 192.168.14.1
Alta(config)# ip route 10.0.234.0 255.255.255.0 192.168.14.2
Alta(config)# ip route 0.0.0.0 0.0.0.0 s0/0/0
Which IPv6 static route would serve as a backup route to a dynamic route learned through OSPF?
Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 200
Which command would create a valid IPv6 default route?
ipv6 route ::/0 2001:db8:acad:2::a
What are two reasons why an administrator might choose to use static routing rather than dynamic routing? (Choose two.)
Static routing is more secure.
Static routing uses less router processing & bandwidth.
A network administrator notices that a correctly entered static route is not in the routing table. What two router commands would an administrator use to determine if the exit interface was up and the next hop address is available? (Choose two.)
show ip interface brief
A network administrator enters the following command into Router1: ip route 192.168.0.0 255.255.255.0 S0/1/0. Router1 then receives a packet that is destined for 192.168.0.22/24. After finding the recently configured static route in the routing table, what does Router1 do next to process the packet?
encapsulates the packet into a frame for the WAN link and forwards the packet out the S0/1/0 interface
Consider the following command:
ip route 192.168.10.0 255.255.255.0 10.10.10.2 5
Which route would have to go down in order for this static route to appear in the routing table?
a static route to the 192.168.10.0/24 network
What type of static route is created when the next-hop IP address and exit interface are specified?
fully specified static route
A _________ network is a network that is accessed by a single route.
Fill in the blank. Refer to the exhibit.
On R1, the command to configure a static route to network 172.16.2.0 by specifying the next-hop IP address is ip route 172.16.2.0 255.255.255.0 ___________.
Which static route statement shows a recursive IPv6 static route?
ipv6 route 2001:db8:cafe:1::/56 2001:db8:1000:10::1
What is a characteristic of a default static route?
It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.
A _____________ static route can be used to provide a backup route to a primary static or dynamically learned route.
What network address and subnet mask combination would be used to create a default static route that matches any IPv4 destination?
0.0.0.0 0.0.0.0 (AKA: quad-zero)
What activity is at the core of every data NW?
What purposes (2) to Routers serve? Name 2.
Move information across inter NW from Src (source) to Dst (destination) and from NW to NW (network); and transfer packets
What (3) ways do routers learn information about remote networks?
1) Using dynamic routing protocols; 2) Manual input (static routes); 3) Combinations of use of both dynamic routing protocols and static routes.
Discuss Static Routes: a) Pros/Advantages;
a) Advantages: Very common & uncomplicated. Do not require same amount of processing (time and labor) & HW overhead (CPU & bandwidth) as dynamic routing protocols; Considered > secure & reliable as they do not advertise over the wire, and the path they route is the same each use; Altho manually input, are easier to manage & operate than automatic routes.
Discuss Static Routes: b) Cons /Disadvantages
Not scalable - must be re-input whenever power or route fail; Do not scale well in large/larger NWs
What two configurations does a "fully specified static route include?
Both the exit interface for ... and the next-hop (Router) ip address.
(AKA: output interface).
the interface on which all packets are sent to the dst (destination network) or the next hop ip address
