Update BGP route policies

This guide describes how to do the following updates to BGP route policies for Cloud Router:

• Remove a BGP route policy
• Add BGP route policy terms
• Update BGP route policy terms
• Remove BGP route policy terms

Remove a BGP route policy

Run the following:

gcloud compute routers remove-route-policy ROUTER_NAME 
\
    --policy-name= BGP_ROUTE_POLICY_NAME 

Replace the following:

• ROUTER_NAME : the name of your Cloud Router
• BGP_ROUTE_POLICY_NAME : the name of the BGP route policy that you want to remove

Add a BGP route policy term

Run the following:

gcloud compute routers add-route-policy-term ROUTER_NAME 
\
    --policy-name= BGP_ROUTE_POLICY_NAME 
\
    --priority= PRIORITY 
\
    --match=" CEL_MATCH_EXPRESSION 
" \
    --actions=" CEL_ACTIONS_EXPRESSION 
"
    --region= REGION 

Replace the following:

• ROUTER_NAME : the name of your Cloud Router
• BGP_ROUTE_POLICY_NAME : the name of the BGP route policy that you want to export
• PRIORITY : the order of this term within the BGP route policy, where lower values indicate higher priority. The accepted range is [0, 2^31).
• CEL_MATCH_EXPRESSION : a Common Expression Language (CEL) element that matches routes that this term applies to
• CEL_ACTIONS_EXPRESSION : a semicolon separated CEL expression for actions to take for items that match this rule
• REGION : the region that the Cloud Router is located in

Update a BGP route policy term

Run the following:

gcloud compute routers update-route-policy-term ROUTER_NAME 
\
    --policy-name= BGP_ROUTE_POLICY_NAME 
\
    --priority= PRIORITY 
\
    --match=" CEL_MATCH_EXPRESSION 
" \
    --actions=" CEL_ACTIONS_EXPRESSION 
" \
    --region= REGION 

Replace the following:

• ROUTER_NAME : the name of your Cloud Router
• BGP_ROUTE_POLICY_NAME : the name of the BGP route policy that you want to export
• PRIORITY : The order of this term within the BGP route policy, where lower values indicate higher priority. The accepted range is [0, 2^31).
• CEL_MATCH_EXPRESSION : a CEL element that matches routes that this term applies to
• CEL_ACTIONS_EXPRESSION : a semicolon separated CEL expression for actions to take for items that match this rule
• REGION : the region that the Cloud Router is located in

Remove a BGP route policy term

Run the following:

gcloud compute routers remove-route-policy-term ROUTER_NAME 
\
    --policy-name= BGP_ROUTE_POLICY_NAME 
\
    --priority= PRIORITY 
--region= REGION 

Replace the following:

• ROUTER_NAME : the name of your Cloud Router
• BGP_ROUTE_POLICY_NAME : the name of the BGP route policy that you want to export
• PRIORITY : the order of this term within the BGP route policy, where lower values indicate higher priority. The accepted range is [0, 2^31).
