The Virtual Router (BGP) – BGP Neighbor Setting page enables you to configure settings that indicate how the current Border Gateway Protocol (BGP) routing instance interacts with its BGP peer.
This page supports both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6) if you set the IPv6 environment variable. The first area of the page contains general parameters that apply to both IPv4 and IPv6. The second area is for IPv4 parameters, and the third area is for IPv6 parameters. If IPv6 is not enabled, the third area will not appear.
This procedure applies to both IPv4 and IPv6 if you set the IPv6 environment variable. Unless otherwise indicated, the descriptions of the user interface are the same for both protocols.
Enter the necessary information:
EBGP Multihop: Select Enable to connect to the peer through multiple, intervening routing nodes. Enter the number of hops for the connection.
Keep Alive: Specifies the number of seconds between keepalive packet transmissions sent by the BGP routing instance to its peer. Select one of the following:
Use node default: Sets the keepalive transmission interval to one-third of the hold time.
Custom: Sets the keepalive transmission interval to the value you specify.
Hold Time: Select Enable to specify the time that can elapse between the receipt of successive KEEPALIVE and UPDATE messages by the local BGP routing instance or its neighbor. Enter the maximum number of seconds. The minimum number of seconds allowed is three.
Retry Time: Enter the number of seconds following an unsuccessful BGP session establishment with a peer that a session establishment by the BGP routing instance is retried.
Peer Authentication: Select Enable to enable Message Digest version 5 (MD5) authentication for the peer. Enter the MD5 password.
Force Reconnect: Select this setting to cause the peer to drop the existing BGP connection and accept a new connection.
Peer Enabled: Select this setting to enable the peer connection.
Send default route to peer: Select this setting to send the IPv4 or IPv6 default route to the peer.
Ignore default route from peer: Select this setting to ignore the IPv4 or IPv6 default route sent from the peer.
Self as next hop: Select this setting to indicate that the next-hop value is the local BGP virtual routing instance.
Send Community: Select this setting to send the community to the peer.
Remove Private As: Select this setting to remove private asynchronous system (AS) numbers from the AS_PATH list before the routes are propagated to a BGP peer.
Reflector Client: Select this setting to designate the neighbor as the route reflector's client.
MED: Enter the value that indicates the preference for entry into the AS. The lower the MED value, the higher the priority of the link.
Weight: Enter the value that indicates the priority of the path between the local BGP virtual routing instance and its neighbor. The higher the value, the greater the priority of the path.
Advertisement Interval: Select Enable toconfigure the advertisement interval for a specific neighbor according to the address family. Enter the interval value.
Route Map: From the lists, select previously configured route maps for incoming or outgoing exchanges with the peer.
Peer Activated: Sets the address family for a neighbor. By default, the IPv4 address family is supported for an IPv4 neighbor and the IPv6 address family is supported for an IPv6 neighbor when the neighbor is created. You should disable the BGP neighbor (clear the Peer Enabled option) before you use this feature so that the new address family can be negotiated through open messages at the session start stage.
