DES-7200 Configuration Guide Chapter 2 Configuring BGP IP VPN

Figure 17 OptionC: enabling IPv4 label switching between EBGP neighbors
The configuration scheme is as follows:
PE1-AS1:
# Configure the loopback interface.
DES-7200# configure terminal
DES-7200(config)# interface loopback 0
DES-7200(config-if-Loopback 0)# ip address 1.1.1.1 255.255.255.255
# Configure the VRF.
The configuration procedure is similar to that of PE1-AS1 in Inter AS VPN OptionB: Next Hop
Unchanged and is not described here.
# Configure a multi-hop MP-EBGP session and disable IPv4 route exchange for the session.
DES-7200# configure terminal
DES-7200(config)# router bgp 1
DES-7200(config-router)# neighbor 5.5.5.5 remote-as 2
DES-7200(config-router)# neighbor 5.5.5.5 update-source loopback 0
DES-7200(config-router)# neighbor 5.5.5.5 ebgp-multihop
