Configuring HoVPN
HoVPN is suited to build hierarchical VPNs, reducing performance requirements for PEs.
Before you configure HoVPN, complete basic MPLS L3VPN settings on UPE and SPE.
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.
