Step 7 Configure the IS-IS route between CE2 and PE2.
# Configure CE2.
[CE2] isis 50
[CE2-isis-50] network-entity 50.0000.0000.0004.00
[CE2-isis-50] quit

[PE2-isis-50] quit
[PE2] interface vlanif50
[PE2-Vlanif50] isis enable 50
[PE2-Vlanif50] quit
Step 8 Set up the MP-BGP peer relationship between PE1 and PE2.
# On PE1, specify PE2 as an IBGP peer, set up the IBGP connection by using the loopback
interface, and enable the capability of exchanging VPN IPv4 routing information between PE1
and PE2.
[PE1] bgp 100
[PE1-bgp] peer 3.3.3.9 as-number 100
[PE1-bgp] peer 3.3.3.9 connect-interface loopback 1
[PE1-bgp] ipv4-family vpnv4
[PE1-bgp-af-vpnv4] peer 3.3.3.9 enable
[PE1-bgp-af-vpnv4] quit
# Enter the view of the BGP VPN instance vpn1 and import the direct routes and IS-IS routes.
[PE1-bgp] ipv4-family vpn-instance vpn1

[PE1-bgp-vpn1] import-route isis 50
# On PE2, specify PE1 as an IBGP peer, set up the IBGP connection by using the loopback
interface, and enable the capability of exchanging VPN IPv4 routing information between PE2
and PE1.
[PE2] bgp 100
[PE2-bgp] peer 1.1.1.9 as-number 100
[PE2-bgp] peer 1.1.1.9 connect-interface loopback 1
[PE2-bgp] ipv4-family vpnv4
[PE2-bgp-af-vpnv4] peer 1.1.1.9 enable
[PE2-bgp-af-vpnv4] quit
# Enter the view of the BGP VPN instance vpn1 and import the direct routes and IS-IS routes.
