peers ever reached, and the number of times a dynamic peer was rejected because the
maximum was reached.
Because dynamic peers always fully inherit their configuration from a peer group, any
features that are available for peers but not for peer group members are not supported
for the dynamic peers. Currently, only ORFs are not supported for peer group members
and therefore are not supported for dynamic peers.
clear bgp ipv6 dynamic-peers
clear ip bgp dynamic-peers
•
Use to remove all dynamic peers in the specified scope.
•
You can specify the IP address of a BGP neighbor or the name of a BGP peer group as
the scope. For IPv4 only, you can also include a VRF in the scope.
•
Use the asterisk (*) to remove all BGP dynamic peers.
•
This command takes effect immediately.
•
Example
host1# clear ip bgp 192.168.1.158 vrf boston5 dynamic-peers
•
There is no no version.
•
See clear bgp ipv6 dynamic-peers.
•
See clear ip bgp dynamic-peers.
neighbor allow
•
Use to configure a peer group to accept incoming BGP connections from any remote
address that matches the specified access list.
•
When the BGP connection is accepted, a dynamic peer is automatically created.
•
This command is supported only for peer groups; it is not available for individual peers.
These dynamic peers are not displayed by the
show configuration command and are
not stored in NVS. However, the dynamic peers are displayed by show commands that
display information about BGP peers, such as show ip bgp neighbors , show ip bgp
summary , and so on.
•
Incoming connections that match the specified access list are rejected if no peer type
has been configured for the peer group.
•
This command takes effect immediately. Any existing dynamic BGP sessions that are
no longer allowed by the new configuration are removed automatically and immediately.
Preexisting dynamic peers that are still allowed by the new configuration are not
affected.
•
All the members of the peer group inherit the characteristic configured with this
command. It cannot be overridden for a specific peer, because the command applies
only to peer groups.
•
Example
host1(config-router)# neighbor promispeers allow remotelist1 max-peers 1023
