[<CommonParameters>] Description
The Set-BgpRoutingPolicy cmdlet modifies the configuration of a BGP routing policy. The cmdlet selects and configures the routes for the routing policy that match the criteria that you specify for this cmdlet. You can set the criteria by specifying the following parameters:
- MatchASNRange
- MatchCommunity
- MatchNextHop
- MatchPrefix
Examples
Example 1: Modify a BGP routing policy
PS C:\> Set-BgpRoutingPolicy -Name "RTPolicy01" -PolicyType ModifyAttribute -NewMED 100 -PassThru
Confirm
BGP routing policy RTPolicy01 could currently be active. Do you want to apply these changes and restart corresponding
peerings?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"):
PolicyName : RTPolicy01
PolicyType : ModifyAttribute
MatchClauses : MatchASNRange : {64522, 64555}
SetClauses : NewMED : 100
AddCommunity : {645:2}This command modifies the routing policy named RTPolicy01. The command sets the ModifyAttribute policy type of the routing policy, and specifies the value 100 for the MED attribute of the BGP routes that match the criteria that you specify for the routing policy.
Example 2: Modify the community attribute of a BGP routing policy
PS C:\> Set-BgpRoutingPolicy -Name "RTPolicy06" -MatchCommunity 100:500 -Force -PassThru
PolicyName : RTPolicy06
PolicyType : Deny
MatchClauses : MatchASNRange : {64545, 64555}
MatchCommunity : {100:500}
SetClauses :This command modifies the MatchCommunity attribute for the BGP routing policy named RTPolicy06. Because the cmdlet uses the Force parameter, the cmdlet modifies the routing policy without prompting the user for confirmation.
Example 3: Modify a BGP routing policy of a routing domain
PS C:\> Set-BgpRoutingPolicy -Name "RTPolicy04" -RoutingDomain "Rd_001" -NewLocalPref 300 -PassThru
Confirm
BGP routing policy RTPolicy04 could currently be active. Do you want to apply these changes and restart corresponding
peerings for routing domain Rd_001?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"):
PolicyName : RTPolicy04
PolicyType : ModifyAttribute
MatchClauses : MatchPrefix : {10.1.4.0/24}
IgnorePrefix : {10.1.4.16/28}
SetClauses : NewLocalPref : 300This command removes the routing policy named RTPolicy04 from the BGP router for the routing domain named Rd_001. The command prompts the user for confirmation before it removes the routing policy.
