The peer upe command specifies a BGP peer or peer group as underlayer provider edge (UPE) of hierarchy of VPN (HoVPN).
The undo peer upe command cancels the configuration.
By default, this function is disabled.
| Parameter | Description | Value |
|---|---|---|
| group-name | Specifies the name of the peer group. | The name is a string of 1 to 47 characters without any space. It is case-sensitive. |
| ipv4-address | Specifies the IPv4 address of a peer. | - |
Usage Scenario
After a UPE is specified on the SPE through the peer upe command, the SPE does not send a specific route to the UPE. If the peer route-policy export command is run on the SPE to configure routing policies for the UPE and certain specific routes can pass the filtration of routing policies, these specific routes can be sent to the UPE.
After you run the peer upe command on an SPE to specify a device as a UPE, the SPE can change the next hops of routes received from the UPE to itself and reflect these routes to the NPE.
Prerequisites
Before you run the peer upe command, the peer as-number command should be used to create a peer or peer group.
Precautions
After the peer upe command is configured, to send the default route 0.0.0.0 to the UPE, you need to run the peer default-originate vpn-instance command on the SPE.
