Item Subitem Notes
MPLS LSR-ID LSR ID is similar to router ID. An LSR ID specifies
an address. LDP, by default, uses this address to
establish LDP sessions, The reachability to the LSR
ID must be ensured. Two ways exist to configure an
LSR ID.
• Generally, the LSR ID is the address of the
loopback interface.
• If the mpls Idp transport-address command is
configured on the interface that connects to the
public network, LDP uses the address specified by
this command to establish an LDP session.
MPLS Enable MPLS in the system view and on the interface
that connects with the public network. You must
configure the policy to trigger the setup of LSPs in the
MPLS view.
LDP Enable LDP in the system view and on the interface
that connects with the public network.
BGP AS -
IBGP Specify the remote PE as the local IBGP peer in the
BGP view.
The interface used
by BGP connections Specify the loopback interface (with a 32-bit mask) as
the egress interface of the session that is used to set up
an IBGP connection between PEs.
VPNv4 address
family The IBGP peer must be enabled in VPNv4 address
family.
VPN instances of
IPv4 address family
Specify the directly connected CE as the EBGP peer.
Import the routes of the network segment between PE
and CE to BGP.
Use PE1 as an example to explain configuration notes for MPLS L3VPN.
CD NOTE
The following section covers only the commands related to MPLS L3VPN. For details about the
configuration, see
Nortel Secure Router 8000 Series Configuration Guide - VPN (NN46240-507).
1. Configuration concerning VPN instances
# Create a VPN instance:
[PE1] ip vpn-instance vpna
# Specify an RD:
[PEl-vpn-instance-vpna] route-distinguisher 100:101
# Specify the export VPN target, which must be consistent with the import VPN target of the
peer PE:
[PEl-vpn-instance-vpna] vpn-target 100:1 export-extcommunity
