The relevant router interfaces are:
•
On CE1, the CE1–PE1 interface is at-2/0/0 with IP address 30.1.1.1/24
•
On PE1:
•
The PE1–CE1 interface is at-2/0/1 with no IP address required
•
The PE1–PE2 interface is ge-5/0/0 with IP address 20.1.1.1/24
•
On PE2:
•
The PE2–CE2 interface is ge-0/2/0 with no IP address required
•
The PE2–PE1 interface is ge-0/2/8 with IP address 20.1.1.10/24
•
CE2 interface is ge-0/0/0 with IP address 30.1.1.10/24
NOTE: These are not complete router configurations.
