Examples # Clear route flap history information about BGP peer 2.2.2.2 of VPN instance vpn1. reset bgp vpn-instance vpn1 2.2.2.2 flap-info route-distinguisher Syntax View route-distinguisher route-distinguisher VPN instance view Default level 2: System level Parameters route-distinguisher: Route distinguisher (RD) for the VPN instance, a string of 3 to 21 characters in one of the following formats: • 16-bit AS number:32-bit user-defined number. For example, 101:3. • 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1. • 32-bit AS number:16-bit user-defined number, where the minimum value of the AS number is 65536. For example, 65536:1. Description Use route-distinguisher to configure a route distinguisher (RD) for a VPN instance. An RD is used to create the routing and forwarding table of a VPN. By prefixing an RD to an IPv4 prefix, you make the VPN IPv4 prefix unique globally. NOTE: • No RD is configured by default; you must configure an RD for each VPN instance. • A VPN instance takes effect only after you configure an RD for it. • Once you configure an RD for a VPN, you cannot remove the association. • You cannot change an RD directly; you can only delete the VPN instance, re-create the VPN instance, and then reconfigure a new RD. Examples # Configure the RD of VPN instance vpn1. system-view [Sysname] ip vpn-instance vpn1 [Sysname-vpn-instance-vpn1] route-distinguisher 22:1 387
