Usage Guidelines

Usage Scenario

In the networking of BGP/MPLS IP VPN, VPN target attributes are used to filter received VPN routes or label blocks. If VPN target attributes are not configured, received VPN routes or label blocks are discarded.

VPNs and VPN target attributes are not configured on the following devices in certain networking scenarios:
  • ASBRs (not functioning as PEs) in inter-AS BGP/MPLS IP VPN OptionB
In this case, VPN routes or label blocks are not saved on the RRs or ASBRs.

The RRs or ASBRs, however, need to save all VPN routes or label blocks sent from PEs. Therefore, the undo policy vpn-target command can be configured on the RRs or ASBRs to disable the filtering of VPN routes or label blocks.


Running the undo policy vpn-target makes all VPN routes or label blocks from PEs received. Therefore, this command is configured only on devices of particular roles (RRs or ASBRs)
