Command Manual – IPv6 Routing
H3C S7500E Series Ethernet Switches
Description
Use the peer allow-as-loop command to configure IPv6 BGP to allow the local AS
number to exist in the AS_PATH attribute of routes from a peer/peer group, and to
configure the repeating times of the local AS number.
Use the undo peer allow-as-loop command to disable the function.
The local AS number is not allowed to exist in the AS PATH attribute of routes by

routes from peer 1::1 as 2.
