Redistributing IBGP routes
27
Syntax: [no] compare-med-empty-aspath
Disabling or re-enabling comparison of the
AS-path length
AS-Path comparison is Step 5 in the algorithm BGP4 uses to select the next path for a route.
Comparison of the AS-Path length is enabled by default. To disable it, enter the following command
at the BGP configuration level of the CLI.
BigIron RX(config-bgp)# as-path-ignore
This command disables comparison of the AS-Path lengths of otherwise equal paths. When you
disable AS-Path length comparison, the BGP4 algorithm shown in “How BGP4 Selects a Path for a
Route” on page 26-3 skips from Step 4 to Step 6.
Syntax: [no] as-path-ignore
Redistributing IBGP routes
By default, the device does not redistribute IBGP routes from BGP4 into RIP, OSPF, or ISIS. This
behavior helps eliminate routing loops. However, if your network can benefit from redistributing the
IBGP routes from BGP4 into OSPF, ISIS or RIP, you can enable the device to redistribute the routes.
To enable the device to redistribute BGP4 routes into OSPF, RIP, or ISIS, enter the following
command.
BigIron RX(config-bgp)# bgp-redistribute-internal
Syntax: [no] bgp-redistribute-internal
To disable redistribution of IBGP routes into RIP, ISIS, and OSPF, enter the following command.
BigIron RX(config-bgp)# no bgp-redistribute-internal
Disabling or re-enabling client-to-client route reflection
By default, the clients of a route reflector are not required to be fully meshed; the routes from a
client are reflected to other clients. However, if the clients are fully meshed, route reflection is not
required between clients.
If you need to disable route reflection between clients, enter the following command. When the
feature is disabled, route reflection does not occur between clients but reflection does still occur
between clients and non-clients.
BigIron RX(config-bgp)# no client-to-client-reflection
Enter the following command to re-enable the feature.
BigIron RX(config-bgp)# client-to-client-reflection
Syntax: [no] client-to-client-reflection
