Border Gateway Protocol (BGPv4)
– 963 –
Command Usage
◆
When MD5 authentication is configured on a TCP connection between two
peers, neighbor authentication occurs whenever routing updates are
exchanged. Authentication must be configured with the same password on
both peers; otherwise, the connection between them will not be made.
◆
If you configure or change the password used for MD5 authentication between
two peers, the local router will not tear down the existing session after you
configure the password. It will attempt to maintain the peering session using
the new password until the BGP hold timer expires. If the password is not
entered or changed on the remote router before the hold timer expires, the
session will time out.
Example
Console(config-router)#neighbor 10.1.1.64 password frost
Console(config-router)#
neighbor peer-group
(Creating)
This command configures a router peer group which can be easily configured with
the same attributes. Use the
no form to remove a peer group.
Syntax
[ no ] neighbor group-name peer-group
group-name – A BGP peer group. (Range: 1-256 characters)
Command Mode
Router Configuration
Default Setting
No peer groups are defined.
Command Usage
◆
Neighbors with the same BGP attributes can grouped into peer groups. This
simplifies the application of various policies, such as filter lists. Other
configuration settings can be applied to a peer-group using any of the
neighbor commands. Any changes made to the peer group affect all
members.Use this command to create a peer-group.
◆
To assign members to a peer group, use the neighbor ip-address peer-group
group-name command.
Example
Console(config-router)#neighbor RD peer-group
Console(config-router)#
