Step 3 Run

Step 4 Run
undo policy vpn-target
The VPN-IPv6 routes are not filtered by the VPN target.
By default, the PE performs VPN target filtering on the received VPN-IPv6 routes. The routes
passing the filter is added to the routing table, and the others are discarded. If the PE is not
configured with IPv6 VPN instance, or the IPv6 VPN instance is not configured with the VPN-
Target, the PE discards all the received VPN-IPv6 routes.
In the inter-AS VPN-Option B mode, if the ASBR does not store information about the IPv6
VPN instance, the ASBR must save all the VPN-IPv6 routing information and advertise it to the
peer ASBR. In this case, the ASBR should receive all the VPN-IPv6 routing information without
the VPN-Target filtering.
