Description
Define a BGP peer group. BGP peer groups share
a common type, peer autonomous system (AS) number, and cluster ID,
if present. To configure multiple BGP groups, include multiple group statements.
By default, the group’s options are identical to the global
BGP options. To override the global options, include group-specific
options within the group statement.
The group statement is one of the statements you
must include in the configuration to run BGP on the routing device.
Each group must contain at least one peer and can establish up to 2048 peers. Before establishing a BGP session, RPD checks for established peer count for the group. If the peer count is more than 2048 then the BGP session fails.
Options
| group-name |
Name of the BGP group |
| link-bandwith auto-sense |
Enable this option to automatically detect the
bandwidth towards the peer and attach the
link-bandwith value to the interface speed over
which the BGP route was received. This prevents a
policy churn when there is a change in the
link-bandwidth of an interface. Make sure that you
also include the |
| send-non-transitive-link-bandwidth |
Enable this option to send non-transitive-link-bandwidth-extended-community towards EBGP neighbors only for link-bandwidth communities. All non-transitive link bandwith community values are advertised including originated or received and readvertised link-bw community. |
The remaining statements are explained separately. See CLI Explorer.
