Procedure
Step 1 Configure IGP.
Assign IP addresses for physical interfaces and loopback interfaces on the backbone network.
Run IGP on each router of the backbone so that PE1, P and PE2 can ping through each other,
and know the loopback address of each other. The detailed configuration procedure is not
mentioned here.
Step 2 Set up an MPLS LDP LSP and MP-IBGP peer relationship.
Set up an MPLS LSP and MP-IBGP peer relationship between the PEs. The detailed
configuration procedure is not mentioned here.
After the configuration given above, run the display mpls ldp session command on P. You can
find the LDP session "Status" between PE1 and P, and that between PE2 and P is "Operational".
The display on P is as follows:
<P> 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.
--------------------------------------------------------------------------
PeerID
-------------------------------------------------------------------------
1.1.1.1:0
3.3.3.3:0
--------------------------------------------------------------------------
TOTAL: 2 session(s) Found.
Run the display bgp vpnv4 all peer command on PE. You can find that the MP-IBGP peer
relationship state is "Established".
Consider PE1 as an example:
<PE1> display bgp vpnv4 all peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 1
Peer
3.3.3.3
Step 3 Create VPN instances and establishing EBGP.
Create the VPN instance named vpn1 on PE and bind it with the interface attached with the CE.
Establish the EBGP peer relationship between PE1 and CE1, and that between PE2 and CE2.
In this manner, the routes on the CE can be imported to the PE. The detailed configuration
procedure is not mentioned.
After the configuration given above, run the display ip vpn-instance command on PE. You can
find the "VPN instance names" contains vpn1.
Consider PE1 as an example:
