config bgp router_id
Description The address of a loopback interface is preferred to an IP address on a physical interface
because the loopback interface is more effective than a fixed interface as an identifier
because there is no physical link to go down.
The user must specify a unique router ID within the network.
This command will reset all active BGP peering sessions.
When a router ID is not configured, the router ID is selected by the following rules:
If a loopback interface is configured, the router ID is set to the IP address of the loopback.
If multiple loopback interfaces are configured, the loopback with the highest IP address is
used.
If no loopback interface is configured, the router ID is set to the highest IP address on a
physical interface.
Note: One newly created interface whose address may be preferred to be the router ID
according to the rules above, but, it will not be chosen to be router ID immediately. Only
when the router ID is set to zero or when recreating a BGP instance, the new interface may
be selected as the BGP router ID.
Parameters
<ipaddr> - An ID to identify a BGP router. If it is set to zero the router ID will be automatically
determined. The default value is the highest IP address on a physical interface.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To configure the BGP process’s router ID:
DGS-3627:admin# config bgp router_id 10.10.10.1
Command: config bgp router_id 10.10.10.1
Success
config bgp synchronization
Purpose This command is used to configure the BGP synchronization ability.
Syntax
config bgp synchronization [enable | disable]
Description Usually, a BGP speaker does not advertise a route to an external neighbor unless that route
is local or exists in the IGP. By default, synchronization between BGP and the IGP is turned
off to allow the BGP to advertise a network route without waiting for route validation from the
IGP. This feature allows routers and access servers within an Autonomous System to have
the route before BGP makes it available to other autonomous systems.
Parameters
enable - Specifies to enable synchronization..
disable - Specifies to disable synchronization. By default, this setting is disabled.
Restrictions Only Administrator and Operator-level users can issue this command.
Example usage:
To enable the BGP process’ synchronization ability:
DGS-3627:admin# config bgp synchronization enable
Command: config bgp synchronization enable
Success
