IPv6 Border Gateway Protocol (IPv6 BGP) | 743
Parameters
Defaults
Not configured.
Command Modes
ROUTER BGP
Command
History
Usage
Information
Loopback interfaces are up constantly and the BGP session may need one interface constantly up to
stabilize the session. The neighbor update-source command is not necessary for directly connected
internal BGP sessions.
neighbor weight
c e s
Assign a weight to the neighbor connection, which is used to determine the best path.
Syntax
neighbor {ipv6-address | peer-group-name} weight weight
To remove a weight value, use the no neighbor {ipv6-address | peer-group-name} weight weight
command.
Parameters
Defaults
0

Information
In the FTOS best path selection process, the path with the highest weight value is preferred.

peer-group-name
Enter the name of the peer group to disable all routers within the peer group.
