Summary Automatic - HP FlexNetwork 3600 v2 Series Command Reference Manual

Default level
2: System level
Parameters
router-id: Router ID in IP address format.
Description
Use router-id to specify a router ID.
Use undo router-id to remove the router ID.
To run BGP protocol, a router must have a router ID (an unsigned 32-bit integer), the unique ID of the
router in the AS.
You can specify a router ID manually. Otherwise, the system selects the highest IP address among
loopback interface addresses as the router ID. If no loopback interface addresses are available, the
system selects the highest IP address among physical interface IP addresses as the router ID.
Specify a loopback interface address as the router ID to enhance network reliability.
If the interface whose IP address is selected as the router ID or the manual router ID is deleted, the
system selects a new router ID for the router.
Examples
# Specifies the Router ID as 10.18.4.221.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] router-id 10.18.4.221

Description
Use summary automatic to enable automatic summarization for redistributed subnets.
Use undo summary automatic to disable automatic summarization.
By default, automatic summarization is disabled.
Neither the default route nor the routes imported using the network command can be summarized
automatically.
The summary automatic command helps BGP limit the number of routes redistributed from IGP to
reduce the size of the routing table.
