The following is a list of networking Mnemonics that can be used as a method of remembering certain aspects of networking.
1.DHCP process:
“DORA” – DHCP process of Discover, Offer, Request, Acknowledge
2. OSI Layers (from Layer 7 to 1):
“All People Seem To Need Data Processing” – application, presentation, session, transport, network, data-link, physical
“Please Do Not Throw Salami Pizza Away” — bottom-to-top (Layer 1 to 7)
3. K values in EIGRP:
“Big Dogs Really Like Me” – bandwidth, delay, reliability, load, MTU
4. Syslog messages (ordered list):
“Every Alley Cat Eats Watery Noodles In Doors” – emergency, alert, critical, error, warning, notification, informational, debugging
another one – “Every Awesome Cisco Engineers Will Need Icecream Daily”
5. OSPFv3 LSA types:
“Routing Networks Is Indeed A Great New Learning Initiative” – router, network, inter-area prefix, inter-area router, AS external, group membership LSA, Type-7 NSSA, link LSA, intra-area prefix
Router LSA – Network LSA – InterArea Prefix LSA – InterArea Router LSA – AS External LSA – Group Membership LSA – NSSA LSA (Not so stubby Area) – Link LSA – IntraArea Prefix LSA
6. BGP best path selection:
“We Love Oranges As Oranges Mean Pure Refreshment” – weight, local preference, origin, AS-path, origin-type, MED, path, router-ID
7. STP root bridge selection:
“Ruined Puzzles Sacrifice Programs” (Root, Path, Sender, Port)
Step 1 : Lowest Root Bridge ID (BID)
Step 2 : Lowest Path cost to Root Bridge
Step 3 : Lowest Sender BID
Step 4 : Lowest Port ID
