CCNA 2: Ch 7: Dynamically Flashcards
What is the purpose of the passive-interface command?
Allows a router to receive routing updates on an interface but not send updates via that interface
What two [2]tasks do dynamic routing protocols perform?
- network discovery
2. update and maintain routing tables
Refer to the exhibit. OSPF is used in the network. Which path will be chosen by OSPF to send data packets from Net A to Net B?
R1, R3, R5, R7
Which two [2] statements are true regarding classless routing protocols?
- allows for use of both 192.168.1.0/30 and 192.168.1.16/28 subnets in the same topology
- sends subnet mask information in routing updates
The command ____ is used in RIP router configuration mode to enable the sending of subnet masks with the routing updates.
version 2
What two [2] actions result from entering the network 192.168.1.0 command in RIP configuration mode on a router?
- Routing updates are sent through all the interfaces belonging to 192.168.1.0
- The network address 192.168.1.0 is advertised to the neighbor routers.
Based on the partial output from the show ip route command, what two facts can be determined about the RIP routing protocol?
- The command no auto-summary has been used on the RIP neighbor router.
- RIP version 2 is running on this router and its RIP neighbor.
Name two [2] distance vectors?
RIPv2
EIGRP
Name two [2] link State?
OSPF
IS-IS
In the context of routing protocols, what is a definition for time to convergence?
the amount of time for the routing tables to achieve a consistent state after a topology change
When configuring RIPng, the ”______” command instructs the router to propagate a static default route.
default-information originate
A destination route in the routing table is indicated with a code D. Which kind of route entry is this?
a route dynamically learned through the EIGRP routing protocol
Which interface will be the exit interface to forward a data packet with the destination IP address 172.16.0.66?
Serial0/0/1
Which route is the best match for a packet entering a router with a destination address of 10.16.0.2?
S 10.16.0.0/24 [1/0] via 192.168.0.9
Which two [2] requirements are necessary before a router configured with a link-state routing protocol can build and send its link-state packets?
- The router has determined the costs associated with its active links.
- The router has established its adjacencies
