IPv4 address family

Use this table to configure the settings for the IPv4 parameters that apply to all of the devices of a BGP neighbor profile.





Entry active
Enables or disables the distribution of IPv4 NLRI of this address family to the BGP neighbors that use this neighbor profile.
Neighbor profile
Contains the name of the corresponding neighbor profile as saved under Routing protocols > BGP > Neighbor profiles.
Routing tag
Specifies that the device only re-distributes routes if they use the routing tag as configured in the routing table. The routes received from the neighbors for this routing tag are stored by the device in the routing table.
Weight
Specifies the default weight for the NLRI. This information influences the preference of identical prefix advertisements that the device receives from different BGP neighbors. The prefix with the higher weight is given preference.
Note: "Weight" is a proprietary attribute that the device does not propagate to other eBGP neighbors in BGP update messages. This attribute is valid on the local router only.
Local preference
Similar to the Weight attribute, this information influences the preference of identical prefix advertisements that the device receives from different BGP neighbors. The prefix with the higher weight is given preference. This value does not override the local preference for prefixes that already have a LOCAL_PREF attribute (for example, with iBGP). The preference of these prefixes has to be modified by a corresponding rule in the BGP policy.
Note: "Local preference" is a BGP standard attribute (LOCAL_PREF) that the device propagates to neighbors via iBGP. All paths have a "local preference" of 100 by default.
Prefix limit
Determines the number of prefixes accepted for each BGP neighbor of the specified neighbor profile. The device rejects all prefixes received beyond this limit.
Communities
Controls which community attributes are sent in the NLRI of this address family to eBGP neighbors that use the referenced neighbor profile. If the options "Standard" and "Extended" are both disabled, the device transmits no community attributes in the NLRI to the eBGP neighbors.
Note: This option is of no relevance for communications with iBGP neighbors.
Use own IP address as next hop
Enables or disables the replacement in the NLRI of the next hop attribute by the device's own IP address. Possible values:
Yes
In the NLRI, the IP address of the next hop is replaced with the device's own IP address.
No
Leaves the IP address of the next hop in the NLRI unchanged.
Always
Always exchanges the IP address of the next hop in the NLRI with its own IP address, even if the device is configured as a route reflector.
Route redistribute
Specifies whether the device forwards certain routes to BGP neighbors of this profile.
  • Static: The device distributes static routes from the routing table to the BGP neighbors.
  • Connected: The device redistributes routes from the networks that it is directly connected to the BGP neighbors.
  • RIP: The device distributes RIP routes from the routing table to the BGP neighbors.
  • OSPF: The device distributes OSPF routes from the routing table to the BGP neighbors.
  • LISP: The device distributes LISP routes from the routing table to the BGP neighbors.
Note: If no option is selected, the device does not redistribute any routes to the BGP neighbors of this neighbor profile (default setting).
Redistribution filter
Name of the prefix-filter list from Prefix lists.
Default action
Defines the default handling of prefixes that are configured in the prefix list. Possible values:
Accept
Deny
