the peer CE or the peer group

Configuring HoVPN

In a HoVPN networking scenario, perform basic MPLS L3VPN settings on UPE and SPE. In addition,

configure the following settings on the SPE:

Specify the BGP peer or peer group as a UPE.

Advertise the default route of the specified VPN instance or routes matching a routing policy to the
UPE.

Create a BGP-VPN instance so the learned VPNv4 routes can be added into the BGP routing table
of the corresponding VPN instance by RTs.
Associating an interface with a VPN instance is not required on the SPE because no interface on
the SPE is directly connected to the customer network.

H3C recommends not configuring the peer default-route-advertise vpn-instance and peer upe

route-policy commands at the same time.
To configure SPE for HoVPN:
