Adding a BGP Peer to Nokia IP40n Security Platform
Nokia IP40 Security Platform supports both internal and external BGP neighbors. Internal
neighbors are in the same autonomous system; external neighbors are in different autonomous
systems. Normally, external neighbors are adjacent to each other and share a subnet, while
internal neighbors can be anywhere in the same autonomous system.
Use the following command to add BGP neighbors:
add bgp neighbor <value ip_address> remote-as <value>
Use the following command to delete a BGP neighbor:
delete bgp neighbor <value ip_address>
Clearing BGP
Clearing a BGP neighbor session resets BGP connections to enable inbound and outbound
policy changes. Use the following commands to clear a BGP neighbor session:
clear bgp <neighbor <value ip_address> | neighbors>
Creating Prefix Lists on Nokia IP40 Security Platform
Prefix lists are used to filter the updates to and from a peer on the basis of network prefixes, and
masks. A prefix list is associated with a sequence number and prefix length range for a specified
prefix and mask. The sequence number determines the order of the lookup and permits heavily
used prefixes. Prefix lists filtering is easier to use and is more efficient than access lists.
Use the following commands to add prefix lists:
add bgp prefix-list <list-name>
Use the following commands to delete prefix lists:
delete bgp prefix-list <all-unused |name <value> [seq-no <value>] >
130
event <on | off >
keepalive <on | off >
update <on | off >
fsm <on | off >
seq-no <value> action <permit | deny>
any prefix <value>
