Can a router support multiple subnets?
4 Answers. 1) It is possible to have multiple subnets “behind” one router; the Internet would be a very broken place with millions more routers needed if it were not. However, your example of using a /16 subnet mask on the LAN interface, with many /24’s connecting to it, is not exactly how it would actually function.
How do I access different subnets?
How to Connect Computers That Are on 2 Different Subnets
- Connect the computers to the network.
- Connect the routers to each other.
- Enable a routing protocol in each subnet’s router.
- Allow time for the routing tables to update.
Which command is used on a Cisco router to display the dynamic IP routing protocols that are running?
show ip route EXEC command
Use the show ip route EXEC command to display the current state of the routing table.
What kind of routing software does Cisco use?
Cisco IOS software provides full-feature routing at Layer 3 and translation at Layer 2 between VLANs. Five different protocols are available for routing between VLANs: All five of these technologies are based on OSI Layer 2 bridge multiplexing mechanisms.
How many subnetworks does a Cisco router support?
Notice that each of the routers in Figure 2 is attached to four subnetworks, one subnetwork is common to both routers. Also, each router has an IP address for each subnetwork to which it is attached. Each subnetwork could potentially support up to 30 host addresses. This brings up an interesting point.
How to configure default route for Cisco switch?
Configure the default route for the switch. From the diagram in the Task section, note that the IP address of the default router is 200.1.1.2. If the switch receives a packet for a network not in the routing table, it forwards it to the default gateway for further processing. From the switch, verify that you can ping the default router.
How to configure intervlan routing on Layer 3 Cisco switches?
If you need information on how to configure VLANs, access ports, and trunking on the 3550, refer to Creating Ethernet VLANs on Catalyst Switches for the specific Cisco IOS version you run on the switch. The information in this document is based on a Catalyst 3550-48 that runs Cisco IOS Software Release 12.2 (44)SE6 EMI.
