Configuring BGP Services
5-45
Parameter: Peer Route Echo Switch
Default: Enable
Options: Enable | Disable
Function: Controls the way the router echoes a BGP route that is selected for
forwarding. (Echoing in this case means advertising the route back to the
peer from which it was received.) If this parameter is enabled, the router
advertises the route back as reachable and includes the local AS. If this
parameter is disabled, the router echoes the route as UNREACHABLE/
withdrawn.
Instructions: If the peer router saves routes that contain its own AS number and is
running short of memory, send an UNREACHABLE echo.
A BGP speaker that participates in inter-AS multicast routing must
advertise a route it receives from one of its external peers. If the router
stores the route in its routing table, it must also advertise it back to the
peer from which the route was received. For a BGP speaker that does
participate in inter-AS multicast routing, such echoing is optional.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.5.1.2.1.33
Parameter: Discard Duplicate Route Switch
Default: Disable
Options: Enable | Disable
Function: Indicates whether BGP discards routes with identical path attributes.
Instructions: This parameter is for RS clients only. When you enable this feature, the
RS client will discard duplicate updates received from route servers in the
same cluster.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.5.1.2.1.34
