Step 3 Enable MPLS and establish the LSP.
Enable MPLS and establish LDP LSP on the ASBR-PE and the PEs in the same AS.
The configuration procedure is not mentioned.
After the configuration, the LDP adjacencies are established between the PE and the ASBR-PEs
in the same AS. Run the display mpls ldp session command on each Switch, and you can find
that the session status is Operational.
Take the display on PE1 for example.
<PE1> display mpls ldp session
LDP Session(s) in Public Network
Codes: LAM(Label Advertisement Mode), SsnAge Unit(DDDD:HH:MM)
A '*' before a session means the session is being deleted.

TOTAL: 1 session(s) Found.
Step 4 Configure IBGP.
Configure MP-IBGP connections between PE1 and ASBR-PE1, and between PE2 and ASBR-
PE2.
# Configure PE1.
[PE1] bgp 100
[PE1-bgp] peer 2.2.2.2 as-number 100
[PE1-bgp] peer 2.2.2.2 connect-interface LoopBack 1
[PE1-bgp] quit
# Configure ASBR-PE1.
[ASBR-PE1] bgp 100
[ASBR-PE1-bgp] peer 1.1.1.1 as-number 100
[ASBR-PE1-bgp] peer 1.1.1.1 connect-interface loopback 1
[ASBR-PE1-bgp] quit
# Configure ASBR-PE2.
[ASBR-PE2] bgp 200
[ASBR-PE2-bgp] peer 4.4.4.4 as-number 200
[ASBR-PE2-bgp] peer 4.4.4.4 connect-interface loopback 1
[ASBR-PE2-bgp] quit
# Configure PE2.
[PE2] bgp 200
[PE2-bgp] peer 3.3.3.3 as-number 200
[PE2-bgp] peer 3.3.3.3 connect-interface loopback 1
[PE2-bgp] quit
After the configuration, run the display bgp peer command, and you can see that the IBGP peer
relation between PE1 and the ASBR-PE in the same AS is in Established state. Take the display
on PE1 for example.
[PE1] display bgp peer
