Basic Configuration Tasks; Enabling Bgp4 On The Router - Foundry Networks Switch and Router Installation And Configuration Manual

5. Optionally change the Keep Alive Time and Hold TIme.
6. Optionally enable fast external fallover.
7. Optionally change the maximum number of BGP4 load sharing paths.
8. Optionally specify a list of individual networks in the local AS to be advertised to remote ASs using BGP4.
9. Optionally change the default local preference, default information originate, default MED (metric), or
administrative distances. (You change these parameters independently of one another.)
10. Optionally configure the router to always compare MEDs (metrics) when choosing a route.
11. Optionally enable synchronization of routes between BGP4 and IGP.
12. Optionally enable automatic summarization of subnets at the classical IP boundaries (classes A, B, and C).
13. Optionally aggregate routes in the BGP4 route table into CIDR blocks.
14. Optionally configure the router as a BGP4 route reflector.
15. Optionally configure the router as a member of a BGP4 confederation.
16. Optionally change the default metric for routes that BGP4 redistributes into RIP or OSPF.
17. Optionally define BGP4 address filters, AS-path filters, or community filters.
18. Optionally define IP prefix lists.
19. Optionally define neighbor distribute lists.
20. Optionally define BGP4 route map entries.
21. Optionally define route flap dampening parameters.
22. Save the changes to flash memory.

Basic Configuration Tasks

The following sections describe how to perform the configuration tasks that are required to use BGP4 on the
Foundry Layer 3 Switch. You can modify many parameters in addition to the ones described in this section. See
"Optional Configuration Tasks" on page 19-27.

Enabling BGP4 on the Router

When you enable BGP4 on the router, BGP4 is automatically activated. To enable BGP4 on the router, enter the
following commands:
USING THE CLI
BigIron> enable
BigIron# configure terminal
BigIron(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
BigIron(config-bgp-router)# local-as 10
BigIron(config-bgp-router)# neighbor 209.157.23.99 remote-as 100
BigIron(config-bgp-router)# write memory
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Select the Enable radio button next to BGP.
3. Enter the local AS number in the Local AS field.
4. Click the Apply button to apply the changes to the device's running-config file.
