The flow shows choosing between static and dynamic routing, how routes are set, and how data is sent.

Execution Sample

Computer Networks

Static Routing:
- Admin sets route manually
- Route stays fixed

Dynamic Routing:
- Routers share info
- Routes update automatically

Shows the basic steps of static and dynamic routing setup and behavior.

Analysis Table

Step	Routing Type	Action	Route Table State	Result
1	Static	Admin manually adds route to 192.168.1.0/24 via Router A	Route to 192.168.1.0/24 via Router A	Route fixed
2	Static	Data packet sent to 192.168.1.10	Route unchanged	Packet sent via Router A
3	Static	Network change: Router A down	Route unchanged	Packet lost or fails
4	Dynamic	Routers exchange routing info	Route to 192.168.1.0/24 via Router B learned	Route updated
5	Dynamic	Data packet sent to 192.168.1.10	Route via Router B	Packet sent via Router B
6	Dynamic	Network change: Router B down	Route updated to Router C	Packet sent via Router C
7	Dynamic	Network stable	Route table stable	Packets sent successfully
8	End	Routing process complete	Final route tables	Data delivery successful

💡 Routing process ends after data is sent and routes are stable or fail.

State Tracker

Variable	Start	After Step 1	After Step 4	After Step 6	Final
Route Table (Static)	Empty	192.168.1.0/24 via Router A	192.168.1.0/24 via Router A	192.168.1.0/24 via Router A	192.168.1.0/24 via Router A
Route Table (Dynamic)	Empty	Empty	192.168.1.0/24 via Router B	192.168.1.0/24 via Router C	Stable routes
Packet Delivery Status	Not sent	Not sent	Not sent	Sent via Router C	Successful or failed depending on routing

Key Insights - 3 Insights

Why does static routing fail when Router A goes down?

Because static routes do not change automatically (see execution_table step 3), the route remains pointing to Router A even though it is down, causing packet loss.

How does dynamic routing adapt to network changes?

Dynamic routing protocols let routers share info and update routes automatically (see execution_table steps 4 and 6), so routes change to available routers like Router B or C.

Is manual setup needed for dynamic routing after initial configuration?

No, after initial setup, dynamic routing updates routes automatically without manual changes (see execution_table steps 4-7).

Visual Quiz - 3 Questions

Look at the execution_table at step 3, what happens to the static route when Router A goes down?

A The route updates to a new router automatically

B The route remains unchanged pointing to Router A

C The route is deleted from the table

D The route switches to Router B

💡 Hint

Check the Route Table State and Result columns at step 3 in execution_table

At which step does dynamic routing first update its route after learning from other routers?

A Step 5

B Step 2

C Step 4

D Step 6

💡 Hint

Look at the Route Table State changes for Dynamic routing in execution_table

If the network changes frequently, which routing type ensures packets keep flowing without manual changes?

A Dynamic routing

B Static routing

C Neither, both fail

D Both require manual updates

💡 Hint

Refer to key_moments about automatic updates and execution_table steps 4-7

Concept Snapshot

Static Routing:
- Routes set manually by admin
- Fixed paths, no automatic updates
- Simple but not flexible

Dynamic Routing:
- Routers share info automatically
- Routes update with network changes
- More complex but adaptive

Full Transcript

This visual execution compares static and dynamic routing. Static routing requires manual setup of routes that remain fixed. If a router goes down, static routes do not change, causing packet loss. Dynamic routing uses protocols where routers exchange information and update routes automatically. This allows data packets to find new paths if network changes occur. The execution table shows step-by-step how routes are added, updated, and used to send data. Variable tracking shows route tables and packet delivery status changing over time. Key moments clarify why static routing can fail and how dynamic routing adapts. The quiz tests understanding of route updates and behavior in different steps. The snapshot summarizes the main differences simply.
