Interior Border Gateway Protocol (IBGP)

Interior BGP (IBGP) is an exterior routing protocol designed to exchange routing information between routing domains (i.e., autonomous systems). However, BGP may be used for routing within a domain. In this application, it is referred to as Interior BGP. You can now configure Oracle Talari Appliances to learn routes and advertise routes using Interior BGP.

To configure Interior BGP (IBGP):

  1. Under Connections, and then [Site Name], and then Route Learning, and then IBGP, and then Basic Settings click the Edit (INSERT ALT TEXT) icon.
  2. Click the Enable checkbox, click the Advertise APN Routes checkbox if you wish to advertise Routes, enter an optional Router ID, and enter the number of the Local Autonomous System to learn routes from and advertise routes to in the Local Autonomous System field. Click Apply to enable IBGP.

    INSERT ALT TEXT

Figure 18: Enable IBGP

  1. Expand IBGP, and then Basic Settings, and then Neighbors and click the Add (+) icon.

INSERT ALT TEXT

Figure 19: Add a Neighbor to a Site with a Single Routing Domain

Note: If there is only one Routing Domain configured, the Routing Domain column will not appear. If Identity is not checked for a specific Virtual IP Address (see the Virtual IP Address Identity section for more details), the associated Virtual Interface will not be available for IP services

  1. For Sites with multiple Routing Domains, choose a Routing Domain from the drop-down. The Routing Domain determines which Virtual Interfaces are available.
  2. Choose a Virtual Interface from the drop-down menu. The Virtual Interface will determine the Source IP Address.
  3. Enter the IP Address of the IBGP Neighbor router in the Neighbor IP field.
  4. In the Hold Time (s) field, enter the Hold Time, in seconds, to wait before declaring a neighbor down (the default is 180).
  5. In the Local Preference (s) field, enter the Local Preference value, in seconds, which is used for selection from multiple IBGP routes (the default is 100).
  6. Click the IGP Metric checkbox to enable the comparison of internal distances to calculate the best route.
  7. In the Password field, enter a password for MD5 authentication of IBGP sessions (authentication is not required).
