The peer default-originate vpn-instance command configures BGP to advertise all default routes related to the specified VPN instance to the specified virtual private network version 4 (VPNv4) peer.
The undo peer default-originate vpn-instance command removes the configuration.
By default, BGP does not advertise its default route to the VPNv4 peer.
| Parameter | Description | Value |
|---|---|---|
| ipv6-address |
Specifies the IPv6 address of a peer. |
The address is in the format of X:X:X:X:X:X:X:X. |
| vpn-instance-name |
Specifies the name of a VPN instance. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
After the peer default-originate vpn-instance command is run, the Superstratum Provider Edge (SPE) sends a default route with the local address as the next hop address to the Underlayer PE (UPE), regardless of whether there is a default route in the local routing table. In this manner, the UPE only needs to maintain the local VPN routes, and all remote routes are replaced by the default route. This reduces the burden on the UPE.
