Configuring IPv6 BGP 
This chapter describes only configuration for IPv6 BGP. For BGP related information, see Configuring 
BG
P . The term router in this chapter refers to both routers and Layer 3 switches. 
Hardware compatibility 
The HP 5500 SI Switch Series does not support IPv6 BGP.  
IPv6 BGP overview 
BGP-4 was designed to carry only IPv4 routing information, so other network layer protocols such as IPv6 
are not supported.  
To support multiple network layer protocols, IETF extended...

Configuring IPv6 BGP basic functions 
Configuration prerequisites 
Before you configure IPv6 BGP basic functions, complete the following tasks: 
•  Specify IP addresses for interfaces. 
•   Enable IPv6. 
Configuration guidelines 
Create a peer group before configuring basic  functions for it. For more information, see Configuring 
IP
v6 BGP peer group .

Configuring a preferred value for routes from a peer or peer 
group 
If you both reference a routing policy and use the command  peer { ipv6-group-name  | ipv6-address  } 
preferred-value  value  to set a preferred value for routes from a peer, the routing policy sets the specific 
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 { ipv6-group-name  | ipv6-address }  preferred-value  value command. For how...

for establishing TCP 
connections to an IPv6 BGP 
peer or peer group.  peer {
 ipv6-group-name  | 
ipv6-address } connect-interface  
interface-type  interface-number
 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.

4.
  Enable default route redistribution into 
the IPv6 BGP routing table.  default-route imported Optional. 
Not enabled by default. 
If the default-route imported
 
command is not configured, 
using the import-route  command 
cannot redistribute any IGP 
default route.
