H3C MSR810 - Ppp Ip-Pool Route

24
Usage guidelines
This command enables the local interface to check whether its IP address and the IP address of the
remote interface are in the same network segment. If they are not, IPCP negotiation fails.
Examples
# Enable the IP segment match feature on Virtual-Template 1.
<Sysname> system-view
[Sysname] interface virtual-template 1
[Sysname-Virtual-Template1] ppp ipcp remote-address match
ppp ip-pool route
Use ppp ip-pool route to configure a PPP address pool route.
Use undo ppp ip-pool route to remove a PPP address pool route.
Syntax
ppp ip-pool route ip-address { mask-length | mask } [ vpn-instance vpn-instance-name ]
undo ppp ip-pool route ip-address { mask-length | mask } [ vpn-instance vpn-instance-name ]
Default
No PPP address pool route is configured.

Parameters
ip-address: Specifies the destination IP address of the PPP address pool route, in dotted decimal
notation.
mask-length: Specifies a mask length for the IP address, in the range of 0 to 32.
mask: Specifies a mask for the IP address, in dotted decimal notation.
vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a
case-sensitive string of 1 to 31 characters. If you do not specify this option, the PPP address pool
route applies to the public network.
Usage guidelines
The BRAS uses PPP address pool routes to control downlink traffic forwarding.
After you configure a PPP address pool route, the BRAS generates a static blackhole route destined
for the specified network. All traffic matching the blackhole route is discarded. When a legal user logs
in, the BRAS adds a host route destined for the specified network. In addition, the BRAS uses a
dynamic routing protocol to redistribute the PPP address pool route to the upstream device.

Make sure the destination network of the PPP address pool route includes the PPP address pool.
You can execute this command multiple times to configure multiple PPP address pool routes.
