In-Depth Information
Are all the relevant interfaces on each router activated (that is, in the up and up state)?
yes
How many interfaces are activated on R1 and R3?
2
Why are there three activated interfaces on R2?
R2 has two WAN links and a LAN link.
View the routing table information for all three routers using the correct command. Begin
with R1.
