Step Command Remarks
9. (Optional.) Enable BGP
VPNv4 route exchange with
the peer CE or the peer group
of the peer CE.
peer { group-name | peer-address
[ mask-length ] } enable By default, BGP does not exchange
VPNv4 routes with any peer.
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:
