DES-7200 Configuration Guide Chapter 2 Configuring BGP IP VPN
2-36
As shown in the preceding figure, the RRs in the two ASs set up a multi-hop MP-EBGP session
to exchange VPN routes. The configuration procedure is as follows:
Configuring Route Exchanging Between PEs and CEs
Configuring an IGP and MPLS Signaling Protocol in an AS
Setting Up an MP-IBGP Session Between the RR and PE to Exchange Labels Through
IPv4 Routes
Setting Up an IBGP Session Between the RR and ASBR to Assign Labels to IPv4 Routes
Setting Up an EBGP Session Between ASBRs to Exchange Labels Through IPv4 Routes
Configuring a Multi-Hop MP-EBGP Session
Configuring Route Exchanging Between PEs and CEs
This procedure is similar to Configuring Route Exchanging Between PEs and CEsand is not
described here.
Configuring an IGP and MPLS Signaling Protocol in an AS
This procedure is similar to Configuring an MPLS Network and is not described here.
Setting Up an MP-IBGP Session Between the RR and PE to Exchange Labels Through IPv4 Routes
Configure a PE to set up an MP-IBGP session with the RR to transmit VPN routes. At the same
time, enable label exchanging of IPv4 routes for the session.
Enter the privilege mode and perform the following configuration procedure:
Command Function
DES-7200# config terminal
Enter the global configuration mode.
DES-7200(config)# router bgp
asn-number
Enable BGP and enter the BGP configuration
mode.
DES-7200(config-router)# neighbor
peer-address
remote-as asn-number
Set up the IBGP session.
DES-7200(config-router)# neighbor
peer-address
update-source interface-name
Use the address of the loopback address as the
source address to set up an IBGP session.
