Configuration procedure
1. Configure CE 1:
# Configure an IP address for VLAN-interface 12.
<CE1> system-view
[CE1] interface vlan-interface 12
[CE1-Vlan-interface12] ip address 30.0.0.2 24
[CE1-Vlan-interface12] quit
# Configure 30.0.0.1 as an EBGP peer, and redistribute direct routes.
[CE1] bgp 65001
[CE1-bgp] peer 30.0.0.1 as-number 100
[CE1-bgp] address-family ipv4 unicast
[CE1-bgp-ipv4] peer 30.0.0.1 enable
[CE1-bgp-ipv4] import-route direct
[CE1-bgp-ipv4] quit
[CE1-bgp] quit
2. Configure PE 1:
# Configure IS-IS on PE 1.
<PE1> system-view
[PE1] isis 1
[PE1-isis-1] network-entity 10.111.111.111.111.00
