Nokia IPSO 4.0 manual BGP Neighbors Example, To configure Ibgp on Nokia Platform a

Note

Make sure that IPSRD is not swapping memory. Look at the memory sizes occupied by user-level daemons like Check Point, ifm, xpand, etc.

To find out how much memory IPSRD occupies, run the following command:

ps -auxww grep ipsrd

The fourth column labeled, %MEM, displays the percentage of memory that IPSRD occupies.

BGP Neighbors Example

BGP has two types: internal and external. Routers in the same autonomous system that exchange BGP updates run internal BGP; routers in different autonomous systems that exchange BGP updates run external BGP.

In the diagram below, AS100 is running IBGP, and AS200 and AS300 are running external BGP.

To configure IBGP on Nokia Platform A

1.Configure the interface as in “Ethernet Interfaces” on page 34.

2.Configure an internal routing protocol such as OSPF or configure a static route to connect the platforms within AS100 to each other.

For more information see “Configuring OSPF” on page 356 or “To configure a default or static route” on page 395.

3.Click BGP under Configuration > Routing Configuration in the tree view.

4.Enter a router ID in the Router ID text box.

The default router ID is the address of the first interface. An address on a loopback interface that is not the loopback address (127.0.0.1) is preferred.

5.Enter 100 in the AS number text box.

6.Enter 100 in the Peer autonomous system number text box.

7.Click Internal in the Peer group type drop-down list; then click Apply.
