BGP dialog box--Generals tab fields


Field Description
AdminStatus
Enables or disables BGP on the current system. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
Note: You cannot enable AdminStatus until you change the LocalAS value to any value other than 0.
LocalAs
Sets a local autonomous system number on the current system. The default value is 0.
  • Specify an integer value in the range 0 to 65535.
Note: You cannot enable AdminStatus until you change the LocalAS default value to any value other other than 0. You cannot change configured values when AdminStatus is set to enable.
Aggregate
Enables or disables the aggregation feature on this interface. The default value is enable.
  • Click the appropriate radio button to enable or disable the option.
Note: You cannot change values when AdminStatus is set to enable.
DefaultMetric
Sets a value that is sent to a BGP neighbor to determine the cost of a route a neighbor is using. This option must be used in conjunction with the redistribute router configuration command to allow the current routing protocol to use the same metric value for all redistributed routes.
The default value is -1.
  • Specify an integer value in the range 0 to 2147483647
Note: A default metric value helps solve the problems associated with redistributing routes that have incompatible metrics. For example, whenever metrics do not convert, using a default metric provides a reasonable substitute and allows the redistribution to proceed.
DefaultLocalPreference
Specifies the default value of the local preference attribute. The default value is 100.
  • Specify an integer value in the range 0 to 2147483647
Note: You cannot change the default value when AdminStatus is set to enable.
DefaultInformationOriginate
Checkbox-- When checked (enabled), allows the redistribution of network 0.0.0.0 into BGP. The default value is disable (not checked).
AlwaysCompareMed
Enables or disables the comparison of the multi-exit discriminator (MED) parameter for paths from neighbors in different autonomous systems. A path with a lower MED is preferred over a path with a higher MED. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
Note: When this option is set to disable (the default value) during the best-path selection process, the MEDs are compared only among paths from the same autonomous system. If you enable this option, the MEDs are compared among paths received from any other autonomous systems.
AutoPeerRestart
Enables or disables the process that automatically restarts a connection to a BGP neighbor. The default value is enable.
  • Click the appropriate radio button to enable or disable the option.
AutoSummary
When enabled, allows BGP to summarize networks based on class limits (For example, Class A, B, C networks). The default value is enable.
  • Click the appropriate radio button to enable or disable the option.
NoMedPathIsWorst
When set to enable (the default value), BGP treats an update that is missing a multi-exit discriminator (MED) attribute, as the worst path.
  • Click the appropriate radio button to enable or disable the option.
BestPathMedConfed
When enabled, allows you to compare multi-exit discriminator (MED) attributes within a confederation. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
DebugMask
Checkboxes--When checked (enabled) allows you to display specified debug information for BGP global configuration. The default value is none (checked).
Mask choices are:
none: disables all debug messages.
all: enables all debug messages.
error: enables display of debug error messages.
packet: enables display of debug packet messages.
event: enables display of debug event messages.
trace: enables display of debug trace messages.
warning: enables display of debug warning messages.
state: enables display of debug state transition messages.
init: enables display of debug initialization messages.
filter: enables display of debug messages related to filtering.
update: enables display of debug messages related to sending and receiving updates.
IgnoreIllegalRouterid
When enabled, allows BGP to overlook an illegal router ID. For example, you can set this command to enable or disable the acceptance of a connection from a peer that sends an open message using a router ID of 0 (zero). The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
Synchronization
Enables or disables the router from accepting routes from BGP peers without waiting for an update from the IGP. The default value is enable.
  • Click the appropriate radio button to enable or disable the option.
MaxEqualCostRoutes
Sets the maximum number of equal-cost-paths that are available to a BGP router by limiting the number of equal-cost-paths that can be stored in the routing table. The default value is 1.
  • Specify an integer value in the range 1 to 4.
IbgpReportImportRoute
Configures BGP to report imported routes to an interior BGP (IBGP) peer. This command also enables or disables reporting of non-BGP imported routes to other IBGP neighbors. The default value is enable.
  • Click the appropriate radio button to enable or disable the option.
FlapDampEnable
Enables or disables route suppression for routes that flap on and off. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
ConfederationIdentifier
Specifies a BGP confederation identifier.
  • Specify an integer value in the range 0 to 65535.
Note: You cannot configure this value when AdminStatus is set to enable.
ConfederationPeers
Lists adjoining ASs that are part of the confederation.
  • Specify a list of ASs separated by commas (5500,65535,0,10,...,...).
RouteReflectionEnable
Enables or disables the reflection of routes from IBGP neighbors. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
RouteReflectorClusterId
Sets a cluster ID. This option is applicable only if the RouteReflectionEnable value is set to enable, and if multiple route reflectors are in a cluster.
  • Specify an IP address that is the cluster ID of the reflector router.
ReflectorClienToClientReflection
Enables or disables route reflection between two route reflector clients. This option is applicable only if the RouteReflectionEnable value is set to enable. The default value is disable.
  • Click the appropriate radio button to enable or disable the option.
