Run the
display bgp
vpnv4
all
peer
command on the PE or the ASBR. If the status of the IBGP
peer between PE and ASBR in the same AS is "Established", and the status of the EBGP peer
between ASBRs in the different AS is "Established", it means that the configuration succeeds.
Run the
display ip routing-table vpn-instance
command on the PE. If the VPN routes are
displayed, it means that the configuration succeeds.
Run the
display mpls lsp
command on the ASBR. If information about the LSP and label is
displayed, it means that the configuration succeeds. If the ASBR is enabled with the next-hop-
based label allocation, only one label is allocated for the VPN routes with the same next hop
and outgoing label.
3.8 Configuring HoVPN
HoVPN indicates a hierarchical VPN, in which multiple PEs play different roles and form a
hierarchical structure. In this manner, these PEs function as one PE, and the performance
requirement for PEs are lowered.
3.8.1 Establishing the Configuration Task
Before configuring HoVPN, familiarize yourself with the applicable environment, complete the
pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
For hierarchical VPN networks, adopt the HoVPN to reduce the requirements for PE devices.
Pre-configuration Tasks
Before configuring HoVPN, complete the task of
Configuring Basic BGP/MPLS IP VPN
.
Data Preparation
To configure HoVPN, you need the following data.
No.
Data
1
Relationship between UPE and SPE
2
Name of the VPN instance sending default routes to UPE
3.8.2 Specifying UPE
Before configuring a UPE, you must establish the VPNv4 peer relationship between the UPE
