Configuring A Preferred Value For Routes From A Peer Or Peer Group; Specifying The Source Interface For Establishing Tcp Connections - HP 3600 v2 series Configuration Manual

Configuring a preferred value for routes from a peer or peer
group
Follow these steps to configure a preferred value for routes received from a peer or peer group:
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Configure a preferred value for
routes received from an IPv6 peer
or peer group
NOTE:
If you both reference a routing policy and use the command peer {
preferred-value
preferred value for routes matching it. If the preferred value in the routing policy is zero, the routes use the
value set with the peer {
use a routing policy to set a preferred value, see the command peer {
ipv6-address
apply preferred-value
Specifying the source interface for establishing TCP
connections
IPv6 BGP uses TCP as the transport layer protocol. By default, IPv6 BGP uses the output interface of the
optimal route to a peer or peer group as the source interface for establishing TCP connections to the peer
or peer group.
If an IPv6 BGP router has multiple links to a peer, and the source interface fails, IPv6 BGP has to
reestablish TCP connections, causing network oscillation. To enhance stability of IPv6 BGP connections,
HP recommends using a loopback interface as the source interface.
Follow these steps to specify the source interface for establishing TCP connections to a BGP peer or peer
group:
To do...
Enter system view
Enter BGP view
Enter IPv6 address family view
Specify the source interface for
establishing TCP connections to an
IPv6 BGP peer or peer group
Use the command...
system-view
bgp as-number
ipv6-family
peer { ipv6-group-name |
ipv6-address } preferred-value
value
value
to set a preferred value for routes from a peer, the routing policy sets the specific
ipv6-group-name
route-policy-name
} route-policy
preferred-value
Use the command...
system-view
bgp as-number
ipv6-family
peer { ipv6-group-name |
ipv6-address } connect-interface
interface-type interface-number
ipv6-address
| } preferred-value
{ import | export } in this document, and the command
in the chapter "Routing policy configuration commands."

By default, IPv6 BGP uses the
outbound interface of the best
route to the IPv6 BGP peer or peer
group as the source interface for
establishing a TCP connection.
