IPv6 Border Gateway Protocol (IPv6 BGP) | 843
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
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
Command Modes
ROUTER BGP
Command
History
Usage
Information
In the FTOS best path selection process, the path with the highest weight value is
preferred.
network
c e
Specify the networks for the BGP process and enter them in the BGP routing table.
Syntax
network ipv6-address prefix-length [route-map map-name]
ipv6-address
Enter the IPv6 address in the x:x:x:x::x format.
The
:: notation specifies successive hexadecimal fields of zeros.
peer-group-name
Enter the name of the peer group to disable all routers within the

Version 8.2.1.0 Introduced on E-Series ExaScale
Version 7.4.1.0 Introduced on E-Series TeraScale
Note: Reset the neighbor connection (capture bgp-pdu max-buffer-size * command)
to apply the weight to the connection and recompute the best path.
