    Configures a device to remove private autonomous system numbers (ASNs) from UPDATE messages that the device sends to a neighbor.
  27. neighbor route-map
    Filters the outgoing and incoming route updates to or from a particular BGP neighbor according to a set of attributes defined in a route map.
  28. neighbor route-reflector-client
    Configures a neighbor to be a route-reflector client.
  29. neighbor send-community
    Enables sending the community attribute in updates to the specified BGP neighbor.
  30. neighbor shutdown
    Causes a device to shut down the session administratively with its BGP neighbor.
  31. neighbor soft-reconfiguration inbound
    Stores all the route updates received from a BGP neighbor.
  32. neighbor timers
    Specifies how frequently a device sends KEEPALIVE messages to its BGP neighbors, as well as how long the device waits for KEEPALIVE or UPDATE messages before concluding that a neighbor is dead.
  33. neighbor update-source
    Configures the device to communicate with a neighbor through a specified interface.
  34. neighbor weight
    Specifies a weight that the device will add to routes that are received from the specified BGP neighbor.
  35. netbios-name-server
    Specifies the IP address of a NetBIOS WINS server or servers available to Microsoft DHCP clients.
  36. netbios-proto
