Quidway S7700 Smart Routing Switch
Configuration Guide - VPN
After the configuration, run the display bgp vpnv6 all peer command on a PE, and you can
find that the BGP peer relation between the PE and the CE is in Established state. By running
the ping ipv6 vpn6-instance, you can see that each PE can ping its connected CE.
Step 5 Configure the default route on the Hub-PE and the Hub-CE.
# Configure the Hub-CE.
<Hub-CE> system-view
[Hub-CE] ipv6 route-static :: 0 2003::2
# Configure the Hub-PE.
# Configure the default route for vpn_out. Set the next hop of the default route as the address
of the Hub-CE.
[Hub-PE] ipv6 route-static vpn6-instance vpn_out :: 0 2004::1
# Advertise the default route through MP-IBGP.
[Hub-PE] bgp 100
[Hub-PE-bgp] ipv6-family vpn6-instance vpn_out
[Hub-PE-bgp6-vpn_out] network :: 0
# Advertise the default route through MP-IBGP.
[Hub-PE-bgp6-vpn_out] import-route direct
[Hub-PE-bgp6-vpn_out] quit
[Hub-PE-bgp] quit
Step 6 Set up MP-IBGP peer relations between PEs.
# Configure Spoke-PE1.
[Spoke-PE1] bgp 100
[Spoke-PE1-bgp] peer 2.2.2.9 as-number 100
[Spoke-PE1-bgp] peer 2.2.2.9 connect-interface loopback 1
[Spoke-PE1-bgp] ipv6-family vpnv6
[Spoke-PE1-bgp-af-vpnv6] peer 2.2.2.9 enable
[Spoke-PE1-bgp-af-vpnv6] quit
# Configure Spoke-PE2.
[Spoke-PE2] bgp 100
[Spoke-PE2-bgp] peer 2.2.2.9 as-number 100
[Spoke-PE2-bgp] peer 2.2.2.9 connect-interface loopback 1
[Spoke-PE2-bgp] ipv6-family vpnv6
[Spoke-PE2-bgp-af-vpnv6] peer 2.2.2.9 enable
[Spoke-PE2-bgp-af-vpnv6] quit
# Configure the Hub-PE.
[Hub-PE] bgp 100
[Hub-PE-bgp] peer 1.1.1.9 as-number 100
[Hub-PE-bgp] peer 1.1.1.9 connect-interface loopback 1
[Hub-PE-bgp] peer 3.3.3.9 as-number 100
Issue 01 (2011-07-15)
NOTE
If multiple interfaces on a PE are bound to the same VPN, you must specify the source IPv6 address when
you run the ping ipv6 vpn6-instance command to ping the CE connected to the peer PE. That is, specify
-a source-ipv6-address in the ping ipv6 vpn6-instance vpn6-instance-name -a source-ipv6-address dest-
ipv6-address command. Otherwise, the ping operation may fail.
NOTE
The Spoke-PE does not need to allow the repeated ASN, because the Switch does not check the AS path
attribute in the routing information advertised by the IBGP peers.
