IPv6 BGP Application Example Configuring BGP
page 4-80 OmniSwitch 6800/6850/9000 Advanced Routing Configuration Guide December 2007
Peer with the external speaker in AS 300 using IPv4 address:
-> ip interface Link_To_AS300 vlan 4
-> ip interface Link_To_AS300 address 30.0.0.2/24
-> ip bgp neighbor 30.0.0.1
-> ip bgp neighbor 30.0.0.1 remote-as 300
-> ip bgp neighbor 30.0.0.1 status enable
Administratively enable BGP:
-> ip bgp status enable
BGP Speaker 3
Assign the speaker to AS 100:
-> ip bgp autonomous-system 100
Administratively disable IPv4 unicast, as this speaker is part of a homogeneous IPv6 domain:
-> no ip bgp unicast
Explicitly configure the router ID and the primary address of the speaker:
-> ip router router-id 10.0.0.3
-> ip router primary-address 10.0.0.3
Peer with the other speakers in AS 100 (for internal BGP, and to create a fully meshed BGP network):
-> ipv6 interface Link_To_Speaker1 vlan 2
-> ipv6 address 2001:DB8:C18:1::2/64 Link_To_Speaker1
-> ipv6 interface Link_To_Speaker2 vlan 3
-> ipv6 address 2001:DB8:C19:1::2/64 Link_To_Speaker2
-> ipv6 bgp neighbor address 2001:DB8:C18:1::1
-> ipv6 bgp neighbor address 2001:DB8:C18:1::1 remote-as 100
-> ipv6 bgp neighbor address 2001:DB8:C18:1::1 activate-ipv6
-> ipv6 bgp neighbor address 2001:DB8:C18:1::1 status enable
-> ipv6 bgp neighbor address 2001:DB8:C19:1::1
-> ipv6 bgp neighbor address 2001:DB8:C19:1::1 remote-as 100
-> ipv6 bgp neighbor address 2001:DB8:C19:1::1 activate-ipv6
-> ipv6 bgp neighbor address 2001:DB8:C19:1::1 status enable
Administratively enable BGP:
-> ip bgp status enable
AS 200
BGP Speaker 4
Assign the speaker to AS 200:
-> ip bgp autonomous-system 200
Enable IPv6 BGP unicast:
-> ipv6 bgp unicast
