R0106-HP MSR Router Series MPLS Command Reference(V7)

288
ppp ipcp ignore local-ip
Use ppp ipcp ignore local-ip to configure PPP to support IPCP negotiation without IP address.
Use undo ppp ipcp ignore local-ip to restore the default.
Syntax
ppp ipcp ignore local-ip
undo ppp ipcp ignore local-ip
Default
PPP does not support IPCP negotiation without IP address, and the local interface must be configured with
an IP address to perform IPCP negotiation with the peer.

Usage guidelines
In an MPLS L2VPN interworking scenario, link layer negotiation packets cannot be delivered on the
network, and Layer 2 connections cannot be established directly between CEs. Therefore, PEs must
establish Layer 2 connections with the connected CEs. For example, on a PPP link, the PE and its
connected CE perform PPP negotiation to establish a PPP connection. The PE cannot use the IP address
of a local interface for IPCP negotiation. To ensure a successful IPCP negotiation, use this command to
configure PPP to support IPCP negotiation without IP address.
On an interface:
• The IPCP negotiation without IP address configuration takes precedence over the IPCP proxy IP
address configuration.
• 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 2/1/0.
