Configuring AS number substitution
IMPORTANT:
Do not configure AS number substitution in normal circumstances. Otherwise, routing loops might
occur.
To use BGP between PE and CE in MPLS L3VPN, VPN sites in different geographical areas should
have different AS numbers. Otherwise, BGP discards route updates containing the local AS number.
If two CEs connected to different PEs use the same AS number, you must configure AS number
substitution on each PE. This substitution can replace the AS number in route updates originated by
the remote CE as its own AS number before advertising them to the connected CE.
