Usage guidelines
In an inter-AS option B scenario, an ASBR-PE must save all incoming VPNv4 routes and advertises those
routes to the peer ASBR-PE. For this purpose, you must execute the undo policy vpn-target command on
the ASBR-PE to disable route target filtering.
Examples
# In BGP VPNv6 address family view, disable route target filtering of received VPNv6 routes.
