Dynamic Routing Protocols

Yesterday I worked on stating routing, which feels inefficient, although I know it will be necessary to do at times.  

Dynamic Verses Static Protocols

Dynamic routes figure out their own protocols, while static routs are build one at a time.  More scalable than static routing. Routers automatically add different subnets, and if those are moved, routers update it. Routers reroute if one route goes down. Static routes will not recover from network being down.  

Route summaries saves memory and CPU usage by creating one single route.  

Routing Protocol & Lab Portion

Basic RIP configuration commands:

RIP updates the routing table, on-going process.






Routing Protocol Types

Two main types.  1. IGP--Interior gateway protocols (IGPS) & 2. Exterior gateway protocols (EGPs)

The only EGP is Border Gateway Protocol. 




Routing Protocol Metrics

Rip uses Hop Count--max hop count is 15. A longer hop length can sometimes be faster if the bandwidth is higher.  EIRP is simple to maintain, calculates quickly, normally choose the best path by default. This is the CISCO proprietary software. OSPF is the open version of EIRP.  IS-IS inks need to be manually configured.

ARP--Address Resolution Protocol

 ARP is a program that helps connect an IP address to a physical address (MAC) over a Local Area Network.   An analogy/pneumonic device.   Apartment's  Real  Person The IP address on a local address is like an apartment's address in a city. It's helpful to get packages delivered, but it doesn't tell the carrier which apartment it is going. ARP helps the packet get from the apartment gate to the apartment door.  Apartment's Real Person.

HSRP Configuration

Image
I began by configuring HSRP for the 10.10.10.0/24 using the IP addresses shown in the topology above. My first step was to check to see if G0/1 has been configured on R1 & R2.   It was not on either router, so I configured them and added a virtual IP address.    After that, I checked to see which was the active router (R2). Then, I checked to see that PC2 could ping the default gateway 10.10.10.1, followed by testing upstream connectivity.   I finished this portion of the lab by checking MAC addresses on the active router, the virtual interface, and PCs.

DHCP External Server

Image
 Looks like I lost the images of my CLI prompts and PC Command Prompts were lost when I recorded the lab work from using a router as the DHCP host.  The second part of the lab is using an external server for DHCP. This process has fewer steps.   After setting the router for DHCP earlier, I cleared the work to start over. This is the lab topology: First, I configured the network to allow the PCs to receive IP addresses from the DHCP server, and then I verified the clients received their IPs from DHCP.  The work was successful!
