BGP Policy Settings
|
BGP Policy Rule |
Determines how BGP routing information is handled. |
|
Include Policy |
Inserts an existing policy "policyname" into the current policy. Included policies can themselves include other policies, up to a maximum level of 10 nested include policies. |
|
Prefix |
Address prefix that you want to advertise to the BGP peers in dotted decimal notation. |
|
Exactly |
Requires the entire prospective IP prefix and netmask to exactly match the IP prefix and netmask specified in the rule. |
|
Prefix Longer than |
When used with the deny keyword, prohibits from the BGP database any prospective IP address with a prefix containing more high-order bits than are specified by the netmask. |
|
AS Path |
Autonomous system path String to against which to compare the prospective IP prefix. Details |
|
Community |
Identifier Tag that categorizes a group of destinations against which to compare the prospective IP prefix. |
|
Local Preference |
Assigns an arbitrary rating Number to an external route for advertisement to internal or confederation-member peers only. Number is a 32-bit integer. |
|
Input Multi-Exit-Disc |
Assigns an arbitrary Number for the learned multiexit discriminator, overriding any that is learned from the peer. Number is a 32-bit integer. The strip keyword causes any multiexit discriminator information learned from a peer to be ignored. input-multi-exit-disc can be abbreviated as imed in this command. Lower numbers indicated an increased preference for a specific route. Use this metric to discriminate amoung multiple exit or entry points between the same pair of neighboring autonomous systems. |
|
Output Multi-Exit-Disc |
Assigns an arbitrary rating Number for the multiexit discriminator to an external route for advertisement to external or confederation member peers only. Number is a 32-bit integer. |
|
Degree of Preference |
Assigns a degree-of-preference for a Number to a route. Number is a 32-bit integer. |
|
Next Hop |
Assigns the IP address to advertise as the next hop. If you do not assign a value, a value is computed automatically for the best possible next hop to reach this route. However, if this peer is configured with the set peer always-next-hop on option, this router's local IP address is always used as the next hop. |
|
Community |
Identifier tag that categorizes a group of destinations against which to compare the prospective IP prefix. |
|
Ignore Community |
Instructs the PortMaster to igore the restrictive keywords no-advertise, no export, and no-export-subconfed when advertising this route to a peerr. Use this keyword in the rule to override thise restriction received from other peers. |
