Enable MPLS and MPLS LDP on the devices and interfaces along the LSP. The
configuration procedure is not mentioned here.
After the configuration, run the display mpls ldp session command, and you can see in
the display that the Session State item is Operational.
Take the display on PE1 and RR as an 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.
------------------------------------------------------------------------------
PeerID Status LAM SsnRole SsnAge KASent/Rcv
------------------------------------------------------------------------------
2.2.2.9:0 Operational DU Active 0000:09:23 2253/2237
------------------------------------------------------------------------------
TOTAL: 1 session(s) Found.
<RR> 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.
----------------------------------------------------------------------
Peer-ID Status LAM SsnRole SsnAge KA-Sent/Rcv
----------------------------------------------------------------------
1.1.1.9:0 Operational DU Active 000:00:02 11/11
3.3.3.9:0 Operational DU Passive 000:00:01 8/8
----------------------------------------------------------------------
TOTAL: 2 session(s) Found.
3. Configure IPv6 VPN instances on PEs.
For the configuration procedure, see Example for Configuring BGP/MPLS IPv6 VPN.
4. Set up the EBGP peer relation between PEs and CEs to import VPN routes.
For the configuration procedure, see Example for Configuring Hub&Spoke (Using
BGP4+).
5. Set up the MP-IBGP peer relation between PEs and RR.
