Hi!

Here's my topology:

스크린샷 2023-06-01 173842.png

It's a assignment given by my network teacher, but I'm having a problem.

The goal is to successfully

ping Router#0

from the PC, but the current

ping to Router#1

has also failed.

What should I do?

Here's configuration of R#1, R#3, L3#0.

R#1

ip route 0.0.0.0 0.0.0.0 10.10.10.1 (left interface of R#0)

ip route 0.0.0.0 0.0.0.0 20.20.20.2 100 (Backup route, it's R#2's left interface)

!

Router ospf 1

Router-id 1.1.1.1

Network 20.20.20.0 0.0.0.3 area 0

Network 20.20.20.4 0.0.0.3 area 0

Default-information originate




R#3

Ip route 0.0.0.0 0.0.0.0 30.30.30.4 (VLAN 10's SVI on L3#0)

Ip route 0.0.0.0 0.0.0.0 20.20.20.14 100

!

Router ospf 1
