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.
