What is Difference between static and dynamic routing tables?
Technically, there is no such thing. The routing table has several entries (think of them as lines); the individual LINES in the routing table can be static or dynamic; and the routing table in its entirety can have both types. A static entry is programmed (hard-coded) by a network administrator. A dynamic entry is one which the router learns from a routing protocol, such as RIP, EIGRP, OSPF, BGP, etc. The routers "talk" to one another, and tell one another that they have routes to certain networks; the router that receives such updates will update its routing table as a result. Such entries are temporary, and expire after a relatively short time.
Why a bridge using filtering table and router using routing table?
A bridge can filter, forward based on its MAC address forwarding table. The bridge will note any MAC address that is the source address on a frame and the port that the frame was received. Then it will forward or filter depending upon the forwarding table. If a MAC address is found on more than one port (because of loops in the network) then the frame is forwarded on both ports. If a frame is received on a port and the destination MAC address is only found on that port then the frame is filtered and discarded. If the destination MAC address is not found in the forwarding table, then the bridge will flood the frame out all ports except the receiving port. A router will build a routing table based on the routing protocol that is being used in the router. The routing protocol (RIP, RIPv2, AS-AS, OSPF etc) will have a method of identifying the best route to send the IP packet to the destination. When an IP frame is received then it will be routed on the best route to the destination
What is the most common static route used in a host computer?
the default gateway is the most common static route used in a host computer. netstat -r is the command line command to obtain the routing table.
Why routing protocol is needed?
Routing protocol is used to dynamically learn routing information so routers know where to send packets. The only other option is to manually define all routers within a network which would be very impractical.
Which principle does a multilayer switch operate?
It combines switching and routing
Which routing protocol maintains a topology table separate from the routing table?
EIGRP
Which type of routing allows routers to automatically build their routing table?
it is dynamic routing.
Describe the role of the routing table on a host and on a router?
Describe the role of the routing table on a host and on a router.
Which command can be used to view a routing table and add modify or remove static entries from the routing table?
route
When will a router select the indicated path as the best match?
After checking with its Routing Table (table creation depends on Routing Protocol).
What three ways are the routing table populated?
1. Do it yourself. 2. Don't do it yourself. 3. Don't have a routing table.
What is the similarities and differences between the windows routing table and the router routing table?
That depends entirely on what Operating System the router is running
Which commands isolate routing table problems?
debug ip routing show ip route
A router that uses the RIP routing protocol has an entry for a network in the routing table It then receives an update with another entry for the same destination network but with a lower hop count?
it will append the update information to the routing table
A router that uses the RIP routing protocol has an entry for a network in the routing table. It then receives an update with another entry for the same destination network but with a lower hop count.?
it will append the update information to the routing table
Can a routing table in a datagram network have two entries with the same destination address?
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.
What type of routing uses information that is manually entered into the routing table?
what type of static route does the administrator configure
