Configuring BGP AS number substitution and SoO attribute
552B
Network requirements
CE 1, CE 2, and CE 3 belong to VPN 1, and are connected to PE1, PE 2, and PE 3. 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.
