BGP Neighbor Groups
The BGP Neighbor Groups feature allows a large number of neighbors to be configured automatically based on a range of neighbors' source addresses.
To configure BGP Neighbor Groups - CLI:
Start by adding a BGP neighbor group:
config router bgp
config neighbor-group
edit <neighbor-group-name>
set remote-as 100
...
(All options for BGP neighbor are supported except password.)
end
Then add a BGP neighbor range:
config router bgp
config neighbor-range
edit 1
set prefix 192.168.1.0/24
set max-neighbor-num 100
set neighbor-group <neighbor-group-name>
next
end
