.

On Router 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 Router 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

.

On Router CE2 interface is

ge-0/0/0

with IP address
