Telematics Chapter 6: Network Layer - Freie Universität Berlin

Distance Vector Routing: Example
Router E receives the vector (D=0,
A=1) which it uses to update the
routing table with D=1 and A=2 using
link L6.
The entry for A over link L4 is already
registered with costs of 2, therefore no
new entry for A is necessary.
Routing table of E after the
update.
A, C, and E now have new
routing tables.
