[<CommonParameters>] Description
The Add-BgpRoutingPolicy cmdlet adds a Border Gateway Protocol (BGP) routing policy to the policy store. The cmdlet selects and configures the routes for the routing policy that match the criteria that you specify for this cmdlet. If you do not set any matching criteria, you must specify the Force parameter to add a BGP routing policy. You can set the criteria by specifying the following parameters:
- MatchASNRange
- MatchCommunity
- MatchNextHop
- MatchPrefix
Examples
Example 1: Add a BGP routing policy that modifies router attributes
PS C:\> Add-BgpRoutingPolicy -Name "RTPolicy04" -PolicyType ModifyAttribute -MatchPrefix 10.1.4.0/24 -IgnorePrefix 10.1.4.16/28 -NewLocalPref 400 -PassThru
PolicyName : RTPolicy04
PolicyType : ModifyAttribute
MatchClauses : MatchPrefix : {10.1.4.0/24}
IgnorePrefix : {10.1.4.16/28}
SetClauses : NewLocalPref : 400This command adds a BGP routing policy named RTPolicy04 to the local BGP router. The routing policy modifies the Local-Pref attribute of the BGP routes that match the value of the MatchPrefix parameter. The command assigns the value of 400 to the Local-Pref attribute of the BGP routes that match the network prefix 10.1.4.0/24. The command specifies that the cmdlet does not modify the Local-Pref attribute of the BGP routes that have the network prefix 10.1.4.16/28.
Example 2: Add a BGP routing policy that disables routes
PS C:\> Add-BgpRoutingPolicy -Name RTPolicy06 -PolicyType Deny -MatchASNRange 64545,64555 -PassThru
PolicyName : RTPolicy06
PolicyType : Deny
MatchClauses : MatchASNRange : {64545, 64555}
SetClauses :This command adds a BGP routing policy named RTPolicy06 to the local BGP router. The routing policy drops the routes that have an ASN in the range of 64545 to 64555 in the As-Path attribute from the BGP best path selection process..
Example 3: Add a BGP routing policy for a routing domain
PS C:\> Add-BgpRoutingPolicy -Name RTPolicy01 -RoutingDomain "Rd_001" -PolicyType ModifyAttribute -MatchPrefix 10.1.4.0/24 -IgnorePrefix 10.1.4.16/28 -NewLocalPref 400 -PassThru | Format-Table

---------- ---------- ------------ ----------
RTPolicy01 ModifyAttribute MatchPrefix : {10.1.4.0/24} NewLocalPref : 400
IgnorePrefix : {10.1.4.16/28}This command adds a BGP routing policy named RTPolicy01 to the BGP router for the routing domain named Rd_001.
The routing policy sets the value of the Local-Pref attribute of the BGP routes that match the value of the MatchPrefix parameter.
The command specifies that the cmdlet does not modify the Local-Pref attribute of the BGP routes that have the network prefix 10.1.4.16/28.
The command passes the results of the cmdlet to the Format-Table cmdlet by using the pipeline operator.
The Format-Table cmdlet formats the output as a table.
