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
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
ipv6-address Enter the IPv6 address in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
peer-group-name Enter the name of the peer group to set the timers for all routers within the peer
group.
weight Enter a number as the weight. The range is from 0 to 65535. The default is 0.
Defaults 0

History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
In the system best path selection process, the path with the highest weight value is preferred.
NOTE: To apply the weight to the connection and recompute the best path, reset the neighbor
connection (the capture bgp-pdu max-buffer-size * command).
network
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]
To remove a network, use the no network ip-address mask [route-map map-name]
command.
Parameters
ipv6-address
prefix-length
Enter the IPv6 address in the x:x:x:x::x format then the prefix length in the /x
format. The range is from /0 to /128.
NOTE: The :: notation specifies successive hexadecimal fields of zeros.
mask Enter the mask of the IP address in the slash prefix length format (for example, /
24). The mask appears in command outputs in dotted decimal format (A.B.C.D).
route-map map-
name
(OPTIONAL) Enter the keywords route-map then the name of an established
route map.
If the route map is not configured, the default is deny (to drop all routes).
Defaults Not configured.
