Setting the “service password-encryption” will encrypt all passwords in the show running-config Ex. Enable and Line clear text passwords. Passwords are encrypted with the MD5 hashing algorithm. Before applying: service password-encryption Enable: service password-encryption Verification:
Enhanced Interior Gateway Routing Protocol (EIGRP) is an open-standard distance vector protocol developed by Cisco. Routers running EIGRP must form neighbors before they can begin to exchange routes. The multicast address for EIGRP communication is over 188.8.131.52.
In this lab we will look at the minimum configuration required to build a redundant and high speed link between two Cisco switches. Configuration Depending on your requirements you will need to use either active or passive. Verification
You can use a Standard Access Control List to allow or deny traffic to a host, network, or any host. In our example below we will deny traffic from the 184.108.40.206/24 to the 10.10.10.0/24 network Topology used: Router-on-a-stick Configuration VerificationOur pings begin to drop from PC-2 to PC-1 after applying the ACL to interface Gi0/0.20
In this lab we will configure the Open Shortest Path First routing protocol (OSPF) between two routers in the same area. With OSPF you must use a wildcard mask in your network statements as shown below. CIDR Information OSPF Configuration Verification From the output above we can see that R2 is the Designated Router (DR) …
RIP (Routing Information Protocol) is a distance vector protocol which uses Hop Counts (Max 15 hops) as a routing Metric. Default RIPv2 Timers Update – 30 Sec Invalid – 180 Sec Hold Down – 180 Sec Flush – 240 Sec Admin Distance – 120 UDP Port – 520 Authentication – MD5 & Plain Multicast Address …
A default static route is required when the destination network is NOT known by the routing table. When is a default static route required?Stub Networks – Networks with only one exit pointLimited by router resources
