Establish eBGP peer relationships between PEs and CEs to allow VPN routes to be redistributed

# Configure CE 1.

<CE1> system-view

[CE1] bgp 65410

[CE1-bgp] peer 10.1.1.2 as-number 100

[CE1-bgp] import-route direct

[CE1-bgp] quit

NOTE:

The configurations for the other three CEs are similar to those for CE 1.

# Configure PE 1.

[PE1] bgp 100

[PE1-bgp] ipv4-family vpn-instance vpn1

[PE1-bgp-vpn1] peer 10.1.1.1 as-number 65410

[PE1-bgp-vpn1] import-route direct

[PE1-bgp-vpn1] quit

[PE1-bgp] ipv4-family vpn-instance vpn2

[PE1-bgp-vpn2] peer 10.2.1.1 as-number 65420

[PE1-bgp-vpn2] import-route direct

[PE1-bgp-vpn2] quit

[PE1-bgp] quit

NOTE:

The configurations for PE 2 are similar to those for PE 1. (Details not shown)

After completing the configurations, issue the display bgp vpnv4 vpn-instance peer command on the PEs.

The output shows that BGP peer relationship has been established between PE and CE, and has reached
the Established state. Take PE 1 as an example:

[PE1] display bgp vpnv4 vpn-instance vpn1 peer

BGP local router ID : 1.1.1.9

Local AS number : 100

Total number of peers : 1 Peers in established state : 1
