How many ACL can you implement on a router which has two wan interface interfaces and one ethernet?
On a Cisco router, you can define all the ACLs you want. However, considernig the ones that are actually assigned to an interface (an unassigned ACL won't do anything useful), you can have one ACL per interface, per direction (in vs. out), and per protocol (for example, IPv4, IPv6, IPX, etc.). If you consider only IPv4, you can have six ACLs for the three interfaces.
What else can I help you with?
Which port should you connect a router to a lan?
It shouldn't matter which port you use unless it involves a network switch.
Which three statement are true regarding the encapsulation an de-encapsulation of packets when traveling through a router?
** The router modifies the TTL field, decrementing it by one.** The router maintains the same source and destination IP.** The router changes the source physical address to the physical address of the exit interface
How do you forward ports on routers and when and why?
To forward ports on your router just login to your router's on-line interface. Port Fowarding is used when a program (lets use FileFind [not a real program]) requests a port the router doesn't understand. Lets say that FileFind requests port 130 on your router, but your router doesn't have a port 130. It does, however, have a 128. The port forwarding tells the request to port 130 to be routed through port 128.
Does a bridge separate collision domains?
No a bridge will transmit all network protocols to all ports, without restriction; thus the term "Bridge." A Router in true bridge mode will do the same, unless you implement some form of route management (managed bridge / router).
What are some general rules to help you determine which type of Ethernet cable (straight-through or crossover) to use to connect different types of network hosts and devices?
When connecting two computers, use cross-over. Cross-over is required to connect the transmit and receive terminals of the two endpoints. When connecting through a router, switch or hub, use straight-through. The router, switch or hub provides the crossover.
What is the router interface?
A router interface is a point of connection between the router and a network segment, allowing data to flow in and out of the router. Each interface can be assigned an IP address, enabling routing decisions based on the destination of the data packets. Interfaces can be physical (like Ethernet ports) or virtual (like VLAN interfaces), and they play a crucial role in the router's ability to manage traffic and connect different networks.
What does designation E0 stand for on a router?
Designation E0 on a router typically stands for "Ethernet 0," indicating the first Ethernet interface on the device. This label is used to identify and manage the specific network interface for connecting to local area networks (LANs) or other devices. In router configurations, interfaces are often numbered sequentially (E0, E1, etc.) to differentiate between multiple Ethernet ports.
Router interface most commonly used to interconnect LANs in a campus network?
Ethernet.
What type of cable used to connect the Ethernet interface on a switch to the Ethernet interface on a router?
To the switch the router is just another host, so it connects with a straight Cat 5 or Cat 6 cable.
What physical interface does a router use to connect to a WAN link?
Ethernet port
Can't we use catcable between router and router?
You need a crossover cable to connect two routers via normal Ethernet interfaces.
What kind of physical interface does a router use to connect to a WAN link?
Ethernet ( not sure )
What are devices connected to host called?
Configure the router ID on both routers. Configure the R2 router interfaces for area 0. Configure a loopback interface on both routers. Configure the proper subnet masks on the router interfaces.
What command will show the status and gives a detailed description for all interfaces on the router?
show ip interface-brief
What method should be used when applying IPv4 addresses to router interfaces on a network?
When applying IPv4 addresses to router interfaces on a network, you would manually configure predictable addresses. For example, the lowest or highest address of the local subnet, on each particular router interface.
How many ports are there in Cabletron Ethernet Bridge/Router Interface Module BRIM-E6 ?
It is a six port ethernet bridge with six computer capability networking.
How is the router ID for an OSPFv3 router determined?
In OSPFv3, the router ID is determined by selecting the highest IP address assigned to an active interface on the router. If no interfaces are available, OSPFv3 will use the highest IPv4 address among the router's loopback interfaces, if configured. If no loopback interfaces are present, and no active IP addresses are available, the router ID remains undefined until one is assigned or the router is restarted. The router ID is essential for uniquely identifying the OSPFv3 router within an OSPF network.
