Passive Interfaces. Starts the RIP routing process. Sets the interface as passive, meaning that routing updates will not be sent out this interface. NOTE: For RIP, the passive-inter-face command will prevent the inter-face from sending out routing updates but will allow the interface to receive updates.

Then, What are two common types of static routes in routing tables choose two?

There are two common types of static routes in a routing table, namely, a static route to a specific network and a default static route. A static route configured on a router can be distributed by the router to other neighboring routers.

What is Eigrp Cisco?

Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.

How does Eigrp show passive interface?

To configure an interface as a passive interface in EIGRP, you’ll use the passiveinterface interface#/# command in EIGRP router configuration mode. To verify rather or not an interface is in passive-mode you can use the show ip protocols command in privileged mode.

Is passive an interface?

Passive mode means that the interface is advertised into the link-state protocol, but the interface does not send or receive protocol control packets, such as ISIS hello and link-state PDUs. In ISIS, the lo0 interface is always passive.

How does Eigrp show passive interface?

To configure an interface as a passive interface in EIGRP, you’ll use the passiveinterface interface#/# command in EIGRP router configuration mode. To verify rather or not an interface is in passive-mode you can use the show ip protocols command in privileged mode.

What are two functions of dynamic routing protocols choose two?

Dynamic routing protocols exist to discover the network, maintain routing tables, and calculate the best path. Having low levels of routing overhead, using the path specified by the administrator, and avoiding the exposure of network information are functions of static routing.

What is default information originate?

defaultinformation originate (OSPF) To generate a default external route into an Open Shortest Path First (OSPF) routing domain, use the defaultinformation originate command.

What is one function of a Layer 2 switch?

Layer 2 switching (or Data Link layer switching) is the process of using devices’ MAC addresses on a LAN to segment a network. Switches and bridges are used for Layer 2 switching. They break up one large collision domain into multiple smaller ones. In a typical LAN, all hosts are connected to one central device.

What function is performed by the OSPF designated router?

The default values are 10 seconds for the hello time, and 40 seconds for the dead time. The usual rule of thumb with OSPF is to keep the dead time value four times the hello interval.

What is the metric that is used by OSPF?

What is the metric that is used by OSPF? OSPF uses cost as a metric. OSPF calculates cost inversely to the bandwidth of an interface. The higher the interface bandwidth, the lower the cost of the interface.

What is no auto summary?

The no autosummary command alters this behavior by enabling EIGRP to advertise the actual. networks, not the classful summary. You should use the no autosummary command when a classful network is divided and portions of the same classful network. exist in different parts of the network topology.

What is the administrative distance of a static route that has been redistributed into Eigrp?

What is the administrative distance of a static route that has been redistributed into EIGRP? Whereas internal EIGRP routes have an administrative distance of 90, redistributed routes, including redistributed static routes, have an administrative distance of 170.

What are two reasons that will prevent two routers from forming an OSPFv2 adjacency choose two?

What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? ( Choose two.)
  • a mismatched Cisco IOS version that is used.
  • mismatched OSPF Hello or Dead timers.
  • mismatched subnet masks on the link interfaces.
  • use of private IP addresses on the link interfaces.

What is the purpose of the passive interface command quizlet?

What is IP OSPF passive interface?

If an interface is configured as a passive interface, it does not participate in OSPF and does not establish adjacencies or send routing updates. However, the interface is announced as part of the routing network. This command requires the LAN Base Services license.

What is a disadvantage of using dynamic routing protocols?

What is a disadvantage of using dynamic routing protocols?
  • They are only suitable for simple topologies.
  • Their configuration complexity increases as the size of the network grows.
  • They send messages about network status insecurely across networks by default.

What is default information originate?

defaultinformation originate (OSPF) To generate a default external route into an Open Shortest Path First (OSPF) routing domain, use the defaultinformation originate command.

How do I disable RIP?

To disable RIP without removing configuration statements, use the shutdown (RIP) command. The exit command returns the switch to global configuration mode. This command configures a RIP instance in the non-default VRF. This command disables a RIP instance in the non-default VRF.

What are some advantages with using Eigrp as the routing protocol in your network?

Other EIGRP advantages include: Easy transition to IPv6 with multi-address family support for both IPv4 and IPv6 networks. Superior scaling of Interior Gateway Protocol (IGP) for large dynamic multipoint (DM) VPN deployments. Very fast rapid convergence times for changes in the network topology.

What is router rip command?

auto-summary (RIP)

To restore the default behavior of automatic summarization of subnet routes into network-level routes, use the auto-summary command in router configuration mode.

What function is performed by the OSPF designated router?

To turn off Auto summarization feature in Enhanced Interior Gateway Routing Protocol (EIGRP), we can use the “no autosummary” command from the Router Configuration mode.

What is Router ID?

To disable RIP without removing configuration statements, use the shutdown (RIP) command. The exit command returns the switch to global configuration mode. This command configures a RIP instance in the non-default VRF. This command disables a RIP instance in the non-default VRF.

What is the administrative distance of a static route that has been redistributed into Eigrp?

What is the administrative distance of a static route that has been redistributed into EIGRP? Whereas internal EIGRP routes have an administrative distance of 90, redistributed routes, including redistributed static routes, have an administrative distance of 170. 27. Two routers, R1 and R2, share a 64 kb/s link.

What default length is used for the OSPF dead interval?

The default values are 10 seconds for the hello time, and 40 seconds for the dead time. The usual rule of thumb with OSPF is to keep the dead time value four times the hello interval.

What default length is used for the OSPF dead interval?

Within OSPF, the role of the Designated Router (DR) and a Backup Designated Router (BDR) is to act as a central point for exchanging of OSPF information between multiple routers on the same, multiaccess broadcast network segment.

How do I advertise a default route in OSPF?

There are two ways to advertise a default route into a normal area. The first is to advertise 0.0. 0.0 into the OSPF domain, provided the advertising router already has a default route. The second is to advertise 0.0.

How do I show Eigrp neighbors?

To display information about neighbors discovered by the Enhanced Interior Gateway Routing Protocol (EIGRP), use the show ip eigrp neighbors command.

What are some advantages with using Eigrp as the routing protocol in your network?

Other EIGRP advantages include: Easy transition to IPv6 with multi-address family support for both IPv4 and IPv6 networks. Superior scaling of Interior Gateway Protocol (IGP) for large dynamic multipoint (DM) VPN deployments. Very fast rapid convergence times for changes in the network topology.

What is the default hold interval Eigrp uses on Ethernet interfaces?

The default EIGRP hello interval defaults to 5 seconds on most interfaces, with NBMA interfaces whose bandwidth is T1 or slower using a hello interval of 60 seconds. The hold time defaults to 15 and 180 seconds, respectively—three times the default hello interval.

How do I disable RIP?

To display information about neighbors discovered by the Enhanced Interior Gateway Routing Protocol (EIGRP), use the show ip eigrp neighbors command.

What default reference bandwidth does OSPF use when calculating the metric?

Open Shortest Path First (OSPF) uses “Cost” as the value of metric and uses a Reference Bandwidth of 100 Mbps for cost calculation. The formula to calculate the cost is Reference Bandwidth divided by interface bandwidth. For example, in the case of 10 Mbps Ethernet , OSPF Metric Cost value is 100 Mbps / 10 Mbps = 10.
