|
Delays sending the BGP Open message until an OPEN message is received. |
Delaying sending the BGP open message | |
|
Specifies the maximum number of routes that BGP will accept for installation into the Routing Information Base (RIB). |
Specifying the maximum routes that BGP will accept for installation into the RIB | |
|
Enables the comparison of the Multi Exit Discriminator (MED) for paths from neighbors in different autonomous systems. |
Enabling comparison of MED for paths from neighbors in different autonomous systems | |
|
Specifies the number of time an Autonomous System number can appear in the AS_PATH. |
Enabling comparison of MED for paths from neighbors in different autonomous systems | |
|
Configures Border Gateway Protocol (BGP) to not consider the autonomous system (AS)-path during best path route selection. |
By default, the AS-path is considered during BGP best path selection. |
Configuring BGP to not consider AS_PATH |
|
Specifies to break ties between routes based the Originator ID value instead of the neighbor’s router ID. |
Breaking ties between routes based on originator ID value | |
|
To configure a Border Gateway Protocol (BGP) routing process to compare identical routes received from different external peers during the best path selection process and to select the route with the lowest router ID as the best path, use the
|
Comparing identical routes received from different external peers | |
|
To configure a Border Gateway Protocol (BGP) routing process to assign a value of infinity (max possible) to routes that are missing the Multi Exit Discriminator (MED) attribute (making the path without a MED value the least desirable path), use the
|
Assigning value of infinity to routes missing MED attribute | |
|
Causes a BGP MED to be set on routes when they are advertised to peers. |
Setting BGP MED on routes when advertised to peers | |
|
A route’s preference specifies how active routes that are learned from BGP (compared to other protocols) will be selected. |
Specifying a route's preference | |
|
Enables or disables client-to-client route reflection. |
When acting as a route-reflector, this functionality is enabled by default. |
Enabling client-to-client route reflection |
|
Specifies the cluster ID to be used when the BGP router is used as a routereflector. |
The cluster ID default is the router ID. |
Specifying cluster ID when BGP router is route-reflector |
