Syntax: set ipv6 next-hop ipv6-address
The ipv6-address parameter specifies the IPv6 global address of the next-hop router. You must
specify the ipv6-address parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
Configuring a BGP4+ peer group
If a peer group has multiple neighbors with similar attributes, you can configure a peer group, then add
neighbors to the group instead of configuring neighbors individually for all parameters.
NOTE
You can add IPv6 neighbors only to an IPv6 peer group. You cannot add an IPv4 neighbor to an IPv6
peer group and vice versa. IPv6 and IPv6 peer groups must remain separate.
To configure a BGP4+ peer group, you must perform the tasks listed below.
1. Create a peer group.
2. Add a neighbor to the local device.
3. Assign the IPv6 neighbor to the peer group.
4. Activate the IPv6 neighbor and peer group.
Creating a BGP4+ peer group
To create a peer group named "peer_group1," enter commands such as the following:
device(config-bgp)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor peer_group1 peer-group
Syntax: neighbor peer-group-name peer-group
Specify a name for the peer group.
To delete the peer group, enter the no form of this command.
Adding a neighbor to a local device
To add the IPv6 address 2001:db8:89::23 of a neighbor in remote AS 1001 to the BGP4+ neighbor
table of a device, enter the following command:
device(config-bgp-ipv6u)# neighbor 2001:db8:89::23 remote-as 1001
NOTE
The example above adds an IPv6 neighbor at the BGP4+ unicast address family configuration level.
This neighbor, by default, is enabled to exchange BGP4+ unicast prefixes. However, if you add an
IPv6 neighbor while at the global BGP configuration or IPv4 BGP unicast address family configuration
level, the neighbor will not exchange BGP4+ unicast prefixes until you explicitly enable it to do so by
entering the neighbor activate command at the BGP4+ unicast address family configuration level.
Syntax: neighbor ipv6-address remote-as as-number
The ipv6-address parameter specifies the IPv6 address of the neighbor. You must specify the ipv6-
address parameter in hexadecimal using 16-bit values between colons as documented in RFC 2373.
