Parameters
router-id: Router ID in IP address format.
Usage guidelines
To run BGP protocol, a router must have a router ID, which is an unsigned 32-bit integer, the unique ID
of the router in the AS.
To enhance network reliability, you can specify the IP address of a local loopback interface as the router
ID.
Examples
# Specifies the router ID as 10.18.4.221.
<Sysname> system-view
[Sysname] bgp 100

Usage guidelines
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.
Examples
# In BGP view, enable automatic route summarization.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] summary automatic
# In BGP-VPN instance view, enable automatic summarization (the VPN has been created).
