Table 5-113. Advanced BGP Configuration Page Parameters
Parameter Description
Client to Client
Reflection
This parameter configures the Route Reflector to support route reflection to
client peers.
By default, the Route Reflector will reflect routes learnt from a client peer to all
other client peers. If required, the administrator can disable this feature by
disabling client-to-client reflection.
If disabled, then the Route Reflector will not advertise routes learnt from a client
peer to other client peers. This occurs when all peers within a cluster are
fully-meshed and the client peer itself is able to advertise routes to other clients
of the route-reflector.
Dampening Half Life
Time
This parameter specifies the time (in seconds) after which a penalty is decreased
by half. Once a route has been assigned a penalty, the penalty is decreased by
half after the half-life time. The possible values are between 600 and 2700. The
default value is 900.
Dampening Reuse
Value
If the penalty associated with a suppressed route falls below this value, the route
is re-used. The possible values are between 15 and 10800.The default value is
500.
Dampening Suppress
Value
A route is suppressed when the penalty associated with the route exceeds this
value. The possible values are between 2000 and 3999. The default value is
3500.
Dampening Max
Suppress Time
This parameter specifies the maximum time (in seconds) a route can be
suppressed. The possible values are between 1800 and 10800. The default
value is 3600.
Dampening Decay
Granularity
This parameter specifies the time granularity in seconds used to perform all
decay computations. The possible values are between 1 and 10800. The default
value is 1.
Dampening Reuse
Granularity
This parameter specifies the time interval between evaluations of the reuse-lists.
Each reuse lists corresponds to an additional time increment. The possible
values are between 15 and 10800. The default value is 15.
Dampening Reuse
Array Size
This parameter specifies the size of the reuse index arrays. This size determines
the accuracy with which suppressed routes can be placed within the set of reuse
lists, when suppressed for a long time. The possible values are between 256 and
65535. The default value is 1024.
Confederation
Identifier
This parameter specifies the BGP confederation identifier. The possible values
are between 1 to 65535. Configuring 0 removes the existing configuration.
Best Path MED
Confed
This parameter enables or disables MED comparison among paths learnt from
confed peers.
Confederation Peers This parameter configures the ASs that belongs to the confederation.
