2. Configure BGP AS number substitution:
# Configure BGP AS number substitution on PE 1, PE 2, and PE 3. For more information about
the configuration, see
# Display routing information on CE 2. The output shows that CE 2 has learned the route
100::/96 from CE 1. A routing loop has occurred because CE 1 and CE 2 reside in the same
site.

[PE1-bgp-default-vpn1] address-family ipv6

# On PE 2, configure the SoO attribute as 1:100 for CE 2.

Verifying the configuration
# PE 2 does not advertise routes received from CE 1 to CE 2 because the same SoO attribute has
been configured. Display the routing table of CE 2. The output shows that the route 100::/96 has
been removed.
