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.
Follow these restrictions and guidelines when you configure HoVPN:
• Do not configure the peer default-route-advertise vpn-instance and peer upe route-policy
commands at the same time.
• Do not connect an SPE to a CE directly. If an SPE must be directly connected to a CE, the VPN
instance on the SPE and that on the UPE must be configured with different RDs.
To configure SPE for HoVPN:
