Configuring BGP Configuring BGP for IPv6
OmniSwitch 6800/6850/9000 Advanced Routing Configuration Guide December 2007 page 4-71
Changing the Local Router Address for an IPv6 Peer Session
By default, TCP connections to an IPv6 peer's address are assigned to the closest interface based on reach-
ability. Any operational local IPv6 interface can be assigned to the IPv6 BGP peering session by explic-
itly forcing the TCP connection to use the specified interface.
The ipv6 bgp neighbor update-source command sets the local IPv6 interface address or name through
which this BGP peer can be contacted.
For example, to configure a peer with an IPv6 address of
2004::1 to be contacted via the IPv6 interface
ipv6IntfVlan2, use the ipv6 bgp neighbor update-source command, as shown:
-> ipv6 bgp neighbor 2004::1 update-source ipv6IntfVlan2
Use the no form of the ipv6 bgp neighbor update-source command to prevent the peer with an IPv6
address of 2004::1 from contacting the speaker via the IPv6 interface ipv6IntfVlan2, as shown:
-> no ipv6 bgp neighbor 2004::1 update-source ipv6IntfVlan2
Note. Alternatively, you can configure a peer with a link-local address of fe80::2d0:95ff:fee2:6ed0, using
the ipv6 bgp neighbor update-source command, as shown below:
-> ipv6 bgp neighbor fe80::2d0:95ff:fee2:6ed0 update-source ipv6IntfVlan2
This command will establish a BGP peering session to establish neighborship.
