Configure BGP General Settings

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 BGP > IPv4 or IPv6.

Step 4

Click General.

Step 5

In General, update the following sections:

  1. 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.

  2. 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.

  3. 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.

  4. 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.
