Typical BGP/MPLS VPN Configuration Example 593
[cust_pe2-bgp] ipv4-family vpnv4
[cust_pe2-bgp-af-vpn] peer ebgp enable
[cust_pe2-bgp-af-vpn] peer 2.1.1.2 group ebgp
4 On each Customer PE, configure the sub-VPN that accesses the network through
the Customer PE.
# Configure cust_pe1.

[cust_pe2-bgp] quit
OSPF Multi-instance CE
Configuration Example
Network requirements
CE router in a VPN achieves service isolation by configuring multiple VPN
instances.
