R2511-HP MSR Router Series MPLS Command Reference(V5)

110
Usage guidelines
If you configure PPP to support IPCP negotiation without IP address on a PE, the PE ignores the local
interface address when it performs IPCP negotiation with the peer CE in the PPP NCP phase.
On an interface, the IPCP negotiation without IP address configuration takes precedence over the IPCP
proxy IP address configuration, and the IPCP proxy IP address configuration takes precedence over the
local interface IP address configuration.
Examples
# Configure PPP to support IPCP negotiation without IP address on interface Serial 2/0.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] link-protocol ppp
[Sysname-Serial2/0] ppp ipcp ignore local-ip
ppp ipcp proxy
Use ppp ipcp proxy to specify an IPCP proxy IP address.
Use undo ppp ipcp proxy to restore the default.
Syntax
ppp ipcp proxy ip-address
undo ppp ipcp proxy
Default
No IPCP proxy IP address is specified.
Views
Interface view
Default command level
2: System level
Parameters
ip-address: Specifies the IPCP proxy IP address.
Usage guidelines
If you specify an IPCP proxy IP address on a device, the device uses this IP address to perform IPCP
negotiation with the peer during the PPP NCP phase.
In an MPLS L2VPN interworking scenario, HP recommends specifying the IPCP proxy IP address as the
IP address of the peer CE.
On an interface, the IPCP negotiation without IP address configuration takes precedence over the IPCP
proxy IP address configuration, and the IPCP proxy IP address configuration takes precedence over the
local interface IP address configuration.
Examples
# Specify the IPCP proxy IP address as 1.1.1.1.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] link-protocol ppp
[Sysname-Serial2/0] ppp ipcp proxy 1.1.1.1
