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 comparing 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.
As a best practice, do not configure the
peer default-route-advertise vpn-instance
and
peer upe
route-policy
commands at the same time.
To configure SPE for HoVPN:
