Policy
|
|
######
|
|
|
|
Policies are used for filtering and traffic management. With policies, network
|
|
administrators could filter and treat traffic
|
|
according to their needs.
|
|
|
|
There could be a wide range of routing policies. Some examples are listed
|
|
below:
|
|
|
|
* Filter traffic based on source/destination address.
|
|
* Set some metric to routes learned from a particular neighbor.
|
|
* Set some attributes (like AS PATH or Community value) to advertised routes
|
|
to neighbors.
|
|
* Prefer a specific routing protocol routes over another routing protocol
|
|
running on the same router.
|
|
|
|
Policies, in VyOS, are implemented using FRR filtering and route maps. Detailed
|
|
information of FRR could be found in http://docs.frrouting.org/
