Configuring BGP AS number substitution and
SoO attribute
When CEs at different sites have the same AS number, configure the BGP AS number substitution
feature to avoid route loss.
When a PE uses different interfaces to connect different CEs in a site, the BGP AS number
substitution feature introduces a routing loop. To remove the routing loop, configure the SoO attribute
on the PE.
For more information about the BGP AS number substitution feature and the SoO attribute, see
