Command Mode
Router Configuration
Default Setting
None
Command Usage
◆
If the specified access list for input or output mode does not exist, all input or
output route updates will be filtered.
◆
The neighbor prefix-list and the neighbor distribute-list commands are
mutually exclusive for a BGP peer. That is, only one of these commands may be
applied in the inbound or outbound direction.
Example
Console(config-router)#neighbor 10.1.1.64 distribute-list RD in
Console(config-router)#
neighbor dont-
capability-negotiate
This command disables capability negotiation when creating connections. Use the
no form to restore the default setting.
Syntax
[ no ] neighbor { ip-address | group-name } dont-capability-negotiate
ip-address – IP address of a neighbor.
group-name – A BGP peer group containing a list of neighboring routers
configured with the neighbor peer-group command.
Command Mode
Router Configuration
Default Setting
Capability negotiation is enabled
Command Usage
Earlier versions of BGPv4 require that when a BGP speaker receives an Open
message with one or more unrecognized Optional Parameters, the speaker must
terminate BGP peering. This command can be used when connecting to a partner
known to use an older BGP version which does not support capabilities negotiation
(RFC 2842), thereby allowing the peering session to continue.
Example
Console(config-router)#neighbor 10.1.1.64 dont-capability-negotiate
Console(config-router)#
