# Execute the display ip vpn-instance command to display VPN instance configurations. Verify
that each PE can ping its attached CE, and ASBR-PE 1 and ASBR-PE 2 can ping each other. (Details
not shown.)
4.
Establish an EBGP peer relationship between PE and CE switches, and redistribute VPN routes into
BGP:
# Configure CE 1.
[CE1] bgp 65001
[CE1-bgp] peer 2001:1::2 as-number 100
[CE1-bgp] address-family ipv6 unicast
[CE1-bgp-ipv6] peer 2001:1::2 enable
[CE1-bgp-ipv6] import-route direct
[CE1-bgp-ipv6] quit
[CE1-bgp] quit
# Configure PE 1.
[PE1] bgp 100
[PE1-bgp] ip vpn-instance vpn1
[PE1-bgp-vpn1] peer 2001:1::1 as-number 65001
[PE1-bgp-vpn1] address-family ipv6 unicast
[PE1-bgp-ipv6-vpn1] peer 2001:1::1 enable
[PE1-bgp-ipv6-vpn1] quit
[PE1-bgp-vpn1] quit
[PE1-bgp] quit
# Configure CE 2.
[CE2] bgp 65002
[CE2-bgp] peer 2001:2::2 as-number 200
[CE2-bgp] address-family ipv6
[CE2-bgp-ipv6] peer 2001:2::2 enable
[CE2-bgp-ipv6] import-route direct
[CE2-bgp-ipv6] quit
[CE2-bgp] quit
# Configure PE 2.
[PE2] bgp 200
[PE2-bgp] ip vpn-instance vpn1
[PE2-bgp-vpn1] peer 2001:2::1 as-number 65002
[PE2-bgp-vpn1] address-family ipv6 unicast
[PE2-bgp-ipv6-vpn1] peer 2001:2::1 enable
[PE2-bgp-ipv6-vpn1] quit
[PE2-bgp-vpn1] quit
[PE2-bgp] quit
5.
Establish an IBGP peer relationship between each PE and the ASBR-PE in the same AS, and an
EBGP peer relationship between the ASBR-PEs:
# Configure PE 1.
[PE1] bgp 100
[PE1-bgp] peer 2.2.2.9 as-number 100
[PE1-bgp] peer 2.2.2.9 connect-interface loopback 0
[PE1-bgp] address-family vpnv6
[PE1-bgp-vpnv6] peer 2.2.2.9 enable
