After you also configure BGP AS substitution on PE 1, the GigabitEthernet interfaces of CE 1 and
CE 2 can ping each other:
<CE1> ping –a 100.1.1.1 200.1.1.1
PING 200.1.1.1: 56 data bytes, press CTRL_C to break
Reply from 200.1.1.1: bytes=56 Sequence=1 ttl=253 time=109 ms
Reply from 200.1.1.1: bytes=56 Sequence=2 ttl=253 time=67 ms
Reply from 200.1.1.1: bytes=56 Sequence=3 ttl=253 time=66 ms
Reply from 200.1.1.1: bytes=56 Sequence=4 ttl=253 time=85 ms

Configuring BGP AS number substitution and SoO
Network requirements
CE 1, CE 2, and CE 3 belong to VPN 1 and connect to PE1, PE 2, and PE 3 respectively.
CE 1 and CE 2 reside in the same site. CE1, CE2, and CE 3 all use AS number 600.
To avoid route loss, configure BGP AS number substitution on PEs. To avoid routing loops, configure a
routing policy on PE1 and PE2 respectively to add the SoO attribute to routes received from CE 1 and CE
2.
