Function

The peer default-route-advertise command configures a BGP device to advertise a default route to its peer or peer group.

Usage Guidelines

Usage Scenario

In a VPN ORF scenario, if a device does not support VPN ORF, you can configure an RR to advertise default VPN ORF routes to a peer group in the BGP-VPN-Target address family view so that the RR establishes a VPN ORF route-based peer relationship with the peer or peer group. In this way, VPN OFR is implemented.

For the specific usage scenario of this command, see "VPN" -> "BGP/MPLS IP VPN Configuration" -> "Configuring VPN ORF" in the Configuration Guide.

Example
