Hub and spoke network
Loopback in router
Int loopback10 //make loopback address
Ip address 11.1.1.1 255.255.255.0 //assign ip address
Exit
Show int loopback10
You can’t assign 127.x.x.x address because it’s dedicated to loopback. Although the interface you try to is loopback.
No int loopback 10 //delete loopback int
R2 to R3 need to go through R1. Round-trip time is doubled.
Debug ip packet // enable debug
Undebug all // disable debug mode
R3# ip route 2.2.2.2 255.255.255.255 172.12.123.1
When ping to 2.2.2.2, result is U.U.U
Ip route 0.0.0.0 .0.0.0.0 172.12.123.2 #Set default route to 172.12.123.2
