Display Parameters Description
BGP Global State BGP global state, In this version, BGP always is enabled.
Version BGP protocol version.
BGP Router Identifier BGP process’s router ID.
Synchronization BGP synchronization state.
Enforce First AS When the setting is enabled, any updates received from an external neighbor, that
does not have the neighbor’s configured Autonomous System (AS) at the beginning
of the AS_PATH in the received update, will be denied.
Local AS Number The local AS number.
Hold Time The system will declare a peer as dead if a keepalive message is received that is
more than the hold time.
Keepalive Interval Frequency that a BGP send keepalive message to peer.
Always Compare MED Enable or disable the comparison of the Multi Exit Discriminator (MED) for paths
from the neighbors in different Autonomous Systems.
Deterministics MED Enable or disable to enforce the deterministic comparison of the Multi Exit
Discriminator (MED) for paths received from the neighbors within the same
Autonomous System.
Med Confed If enabled, the BGP process will compare the MED for the routes that are received
from confederation peers.
Default Local Preference Specifies the default local preference value. The default value is 100.
AS Path Ignore If enabled, the BGP process will ignore the AS path in the path selection process. By
default this value is disabled.
Compare Router ID If enabled, the BGP process will include the router ID in the path selection process.
Similar routes are compared and the route with the lowest router ID is selected. By
default this value is disabled.
MED Missing as Worst If enabled, the BGP process will assign a value of infinity to routes that are missing
the Multi Exit Discriminator (MED) attribute.
Compare Confederation Path If enabled, the BGP process will compare the confederation AS path length of the
routes received. The shorter the confederation AS path length, the better the route
is.
