Configure Route maps, Administrative Route Distances, Synchronization, Next-hop, and packet forwarding. The defaults for these settings are appropriate in most cases, but you can adjust them to fit the needs of your network.
Procedure
Step 1 | On the Device Management page, click Routing. |
Step 2 | (For a virtual-router-aware device) From the virtual routers drop-down, select
the virtual router for which you are configuring BGP. |
Step 3 | Choose or IPv6. |
Step 4 | Click General. |
Step 5 | In General, update the following sections:
-
In the Settings section, enter or select a
Route Map object and click
OK.
Note |
The Route Map field is applicable only to
IPv4 settings.
|
-
In the Administrative Route Distances section,
update the following as required, and click
OK:
-
External — Enter the administrative
distance for external BGP routes. Routes are external when
learned from an external autonomous system. The range of
values for this argument are from 1 to 255. The default
value is 20.
-
Internal — Enter administrative
distance for internal BGP routes. Routes are internal when
learned from peer in the local autonomous system. The range
of values for this argument are from 1 to 255. The default
value is 200.
-
Local — Enter administrative distance
for local BGP routes. Local routes are those networks listed
with a network router show command, often as back doors, for
the router or for the networks that is being redistributed
from another process. The range of values for this argument
are from 1 to 255. The default value is 200.
-
In the Routes and Synchronization section,
update the following as required, and click OK:
-
(Optional) Generate default routes —
Check the check box of this option to configure
default-information originate.
-
(Optional) Summarize subnet routes into
network-level routes — Check the check box
of this to configure automatic summarization of subnet
routes into network-level routes. This check box is
applicable only to IPv4 settings.
-
(Optional) Advertise inactive routes —
Check the check box of this to advertise routes that are not
installed in the routing information base (RIB).
-
(Optional) Synchronize between BGP and IGP
system — Check the check box of this to
enable synchronization between BGP and your Interior Gateway
Protocol (IGP) system. Usually, a BGP speaker does not
advertise a route to an external neighbor unless that route
is local or exists in the IGP. This feature allows routers
and access servers within an autonomous system to have the
route before BGP makes it available to other autonomous
systems.
-
(Optional) Redistribute IBGP into IGP
— Check the check box of this to configure iBGP
redistribution into an interior gateway protocol (IGP), such
as OSPF.
-
In the Forward Packets over Multiple Paths
section, update the following as required and click
OK:
-
(Optional) Number of Paths — Enter the
maximum number of Border Gateway Protocol routes that can be
installed in a routing table. The range of values are from 1
to 8. The default value is 1.
-
(Optional) IBGP Number of Paths —
Enter the maximum number of parallel internal Border Gateway
Protocol (iBGP) routes that can be installed in a routing
table. The range of values are from 1 to 8. The default
value is 1.
