BGP Aggregate Address Settings

This window is used to create an aggregate entry in the Border Gateway Protocol (BGP) database.
To view this window, click L3 Features > BGP > BGP Aggregate Address Settings, as shown below:
To configure BGP aggregate address settings on the Switch, complete the following fields:
®
xStack DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch
Used to enable or disable AS Path Ignore, Compare Router ID, Med Confed, MED Missing
As Worst, and Compare Confed Aspath. The default is Disabled.
Enter a default local preference between 0 and 4294967295. The default value is 100.
This field is used to set BGP router ID. An ID to identify a BGP router. If it is set to zero the
router ID will be automatically determined. User must specify a unique router ID within the
network.
The valid values are from 0 to 65535. The system will declare a peer as dead if a keepalive
message is received that is more than the hold time. The default value is 180 seconds. If the
holdtime is set to zero, then the holdtime will never expire. If the two routers that build a BGP
connection have a different hold time, then the smaller hold time will be used. If the timer is
specified for specific neighbors, then the neighbor specific timer will take effect. The hold time
needs to be at least three times that of the keepalive timer.
The valid values are from 0 to 65535. This specifies the interval at which keepalive messages
are sent to its peer. If the keepalive value is set to zero, then the keepalive message will not
be sent out. The default value is 60 seconds. If the two routers that build a BGP connection
have a different keepalive timer, then the smaller keepalive timer will be used. If the timer is
specified for specific neighbors, then the neighbor specific timer will take effect.
Enter the BGP scan timer value from 5 to 60 seconds or tick the Default check box. The
default value is 60 seconds.
Enable or disable fast external fallover. This configures a Border Gateway Protocol (BGP)
routing process to immediately reset its external BGP peer sessions if the link used to reach
these peers goes down. The default state is Enabled.
Enable or disable aggregate next hop check. This is used to configure the BGP aggregated
routes' next hop check. Only the routes with the same next hop attribute can be aggregated if
the BGP aggregate next hop check is Enabled. The default state is Disabled.
