Active
List box {On; Off}, default = "Off"
Enables the dynamic routing and the BGP protocol.
Router ID
IP address, default = 0.0.0.0
M!DGE3 unit acts in the BGP network as a dynamic router. Every router is identified by an ID having
the format of an IP address. This IP address does not have to be ‘real’. Router ID is shared with
the OSPF protocol.
Local AS
Number {0 – 2
32
-1}, default = 65000
Local Autonomous System identification number. AS numbers are assigned by IANA. Part of the
range is reserved for private network usage: 64512 – 65534 and 4200000000 – 4294967294. AS
numbers from this range can be safely used by anyone.
Preference
Number {0 – 2
32
-1}, default = 100
Router preference within the local AS. The higher the number, the higher the preference.
MED (Multi-Exit Discriminator)
List box {Off; Static; OSPF metric 1}, default = "Off"
Setting of MED (Multi-Exit Discriminator) on the routing rules being exported to other AS. MED
makes it possible to advertise which of the routers in the local AS is the preferred input point to the
AS. "Static" option sets the fixed value for all rules (
Static MED ). "OSPF metric 1" copies the OSPF
metric to MED; for the rules which are not from the OSPF it enters the fixed value Static MED .
Static MED
Number {0 – 2
32
- 1}, default = 0
Metric to be used for the preferred input point to the AS selection (see MED (Multi-Exit Discriminator)
description). The higher the number the lower the preference.
Route reflector
List box {Off; On}, default = "Off"
Enables the Route reflector function on this router. iBGP requires connection in between all routers
under normal circumstances. Route reflector makes it possible to avoid this requirement by distrib-
uting routing updates to all its clients. Such clients do not need any other connection except con-
