Usage Guidelines

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.

Example

# Advertise default routes of vpn1 to VPNv4 peer 2001:db8:1::2.
