IP routing is basically the process of moving packets from one network to another network using routers.
Router use routing protocol to dynamically find all the networks within the great internetwork and to ensure that all router have the same routing table, routing protocols are also employed to determine the best path a packet should through an internetwork to get its destination most effectively. RIP, RIPv2, OSPF, and EIGRP are the most common routing protocols.
Routed protocols can be used to send user data (packets) through the established enterprise. Routed protocols are assigned to an interface and determine the method of packet delivery. E.g. IP and IPv6.
The three type of routing method.
Ø Static routing
Ø Default routing
Ø Dynamic routing
Static routing is the process that ensure when you manually add routes in each router’s routing table. There are the advantages and disadvantages of Static Routing.
Here the advantages:
· There is no overhead on the router CPU.
· There is no bandwidth usage between routers.
· It adds security because of you, the administrator, can be very exclusive and choose to allow routing access to certain networks only.
And here are the disadvantages:
· The administrator is must have a vault-tight knowledge of the internetwork and how each router is connected in order to configure routes correctly. If you don’t have a good, accurate map of your internetwork, things will get very messy.
· If you add a network to the internetwork, you have to tediously add a route to it on all routers by hand.
· It’s just not feasible to use it in most large networks because maintaining it would be a full-time job in itself.
Here’s the command syntax you use to add a static route to a routing table from global
ip route [destination network] [mask] [next-hop address or exit interface] [administrative distance] [permanent]
ip route- the command used to change the static route.
Destination network- the network you’re placing in the routing table
Mask-the subnet mask being used on the network
Next-hop address- this is ip address o the next-hop router that will receive packets and forward them to the remote network.
Exit interface- used in place o the next-hop address if you want, and show up as a directly connected route.
Administrative- distanceby default, static routes have an administrative distance o 1 or 0. Next-hop AD is 1, and exit interface AD is 0.
Permanent- if the interface is shut down or the router can’t communicate to the next-hop router, the route will automatically discarded from the routing table by default. Choosing the permanent option keeps the entry in the routing table no matter what happens.
Just like to share something I came across for the first time tonight-

When Host Onboarding a Meraki AP to the Fabric Edge port, you choose a device type of "Server" which basically configures this port as a trunk. In the DNAC User Guide, it states the following constraints for the Fabric Edge port: ...
Anyone know if it is possible to copy (or export) the topology maps made (and saved as Manual Layout) by a user to another user?In older versions of Cisco Works LMS it was possible, but I can't find a way to do it with PI.
Cisco 2509-RJ freezes during start-up I bought some Cisco 2509-RJ terminal server to work on my labs and was working fine. Today I turned it on and half way through starting up it seems to freeze. I can only find one instance of this happing to ...
My question is similar to this one:Prime Infrastructure , do not see correct device type But the command no snmp-server sysobjectid type stack-oid does not work on IOS-XE. Is there a similar fix for this issue?
