256BConfiguring BGP AS number substitution and SoO attribute
507BNetwork requirements
CE 1, CE 2, and CE 3 belong to VPN 1, and are connected 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 the same SoO attribute on PE 1 and PE 2 for CE 1 and CE 2.
