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 to add the SoO attribute to routes received from CE 1 and CE 2.
