OPTIONAL FLAGS
--advertised-route-priority=ADVERTISED_ROUTE_PRIORITY
The priority of routes advertised to this BGP peer. In the case where there ismore than one matching route of maximum length, the routes with lowest priorityvalue win. 0 <= priority <= 65535. If not specified, will useGoogle-managed priorities.
--advertisement-mode=MODE
The new advertisement mode for this peer.MODE must beone of:
CUSTOM

DEFAULT

If specified, remove MD5 authentication from the BGP peer.
--custom-learned-route-priority=PRIORITY
An integral value0 <= priority <=65535, to beapplied to all custom learned route IP address ranges for this peer. If notspecified, a Google-managed priority value of 100 is used. The routes with thelowest priority value win.
--[no-]enable-ipv4

--region=REGION
Region of the router to operate on. If not specified, you might be prompted toselect a region (interactive mode only).

To avoid prompting when this flag is omitted, you can set thecompute/region property:

gcloudconfigsetcompute/regionREGION

A list of regions can be fetched by running:

gcloudcomputeregionslist

To unset the property, run:

gcloudconfigunsetcompute/region

Alternatively, the region can be stored in the environment variableCLOUDSDK_COMPUTE_REGION.

--set-advertisement-groups=[GROUP,…]

--bfd-session-initialization-mode=BFD_SESSION_INITIALIZATION_MODE
The BFD session initialization mode for this BGP peer. Must be one of:

ACTIVE - The Cloud Router will initiate the BFD session for this BGP peer.

PASSIVE - The Cloud Router will wait for the peer router to initiate the BFDsession for this BGP peer.

DISABLED - BFD is disabled for this BGP peer.

BFD_SESSION_INITIALIZATION_MODE must be one of:

ACTIVE
The Cloud Router will initiate the BFD session for this BGP peer.
DISABLED
BFD is disabled for this BGP peer.
