[ASBR-PE2-Pos1/0/0] mpls
[ASBR-PE2-Pos1/0/0] mpls ldp
[ASBR-PE2-Pos1/0/0] quit
[ASBR-PE2] interface pos2/0/0
[ASBR-PE2-Pos2/0/0] mpls
[ASBR-PE2-Pos2/0/0] quit
Note:
In this scenario, ASBRs are connected through POS interfaces encapsulated with PPP.
MPLS capability should be enabled on the interfaces to perform MPLSCP negotiation,
thus to forward MPLS packet. MPLS capability need not to be enable if the interfaces
adopt other link layer protocol.
# Configure basic MPLS capability on PE2 and enable LDP on the interface connecting
ASBR-PE2.
[PE2] mpls lsr-id 162.1.1.2
[PE2-mpls] lsp-trigger all
[PE2-mpls] quit
[PE2] mpls ldp
[PE2-mpls-ldp] quit
[PE2] interface pos1/0/0
[PE2-Pos1/0/0] mpls
[PE2-Pos1/0/0] mpls ldp
[PE2-Pos1/0/0] quit
After the configuration, the LDP neighbor relationship should be established between
PE and ASBR-PE in the same AS. Executing the display mpls ldp session command
on the routers, you can find the Session State is "Operational" in the display result.
3) Configuring VPN instances on PEs and binding to the interfaces connecting to
CEs
Note:
In this part:
The configurations on CE1, CE2, PE1, and PE2 are the same as those in section
3.4.11 "Configuring Inter-Provider Backbones Option B".
# Configure CE1.
