By default, it is 30 seconds for external peers and 5 seconds for internal peers.
Router Configuration Mode.
Address Family Configuration Mode (VRF).
Level: 8. (EI Mode Only Command)
If you specify a BGP peer group, by using the PEER-GROUP-NAME argument, all
the members of the peer group will inherit the characteristic configured with this
command.
Use the show ip bgp neighbors or show ip bgp peer-group command to verify
your settings.
This example shows how to set the minimum time interval between sending BGP
routing updates to 15 seconds.
Specifies the IP address of the BGP peer.
Specifies the name of a Border Gateway Protocol (BGP) peer group. The maximum
length is 16 characters.
(Optional) Specifies the maximum number of local AS to allow appearing in the AS-
path attribute of the update packets. The value is from 1 to 10. If no number is
supplied, the default value of 3 times is used.
By default, this option is disabled.
Router Configuration Mode.
Address Family Configuration Mode (IPv4 Unicast, VPNv4 and VRF).
Level: 8. (EI Mode Only Command)
The BGP router will do AS path loop checks for the received BGP update packets. If
the BGP router's own AS appears in the AS path list, it is identified as a loop and the
packets will be discarded. If the allowas-in setting is enabled, the BGP router's own
AS is allowed in the AS path list.
Use the show ip bgp neighbors or show ip bgp peer-group command to verify
your settings.
This example shows how to set the number of times of the local router's own AS to
allow appearing in the update packets received from the neighbor 100.16.5.4 to 5.
