no neighbor {<ip-address>|<TAG>} allowas-in
Function:
Configure the counts same AS is allowed to appear in the neighbor route AS table. The "no
neighbor {<ip-address>|<TAG>} allowas-in" restores to not allow any repeat.
Parameter:
<ip-address>: IP address of the neighbor.
<TAG>: Name of the peer group.
<1-10>: Allowed count of same AS number.
Default:
In default conditions AS is not allowed repeating in the same route, and when set the repeat count it
is defaulted at 3 when <1-10> parameters not set.
Command Mode:
BGP route mode and address family mode
Usage Guide:
Normally BGP will not allow same AS number appears in the route more than one time. The system
will deny a route when its AS number appears in the AS-PATH. However to support some special
needs, especially the VPN support, the extended BGP allows the AS re-appear counts by
configuration. This command is for configure the re-appear counts.
Example:
Allow the same AS to appear in the route three times for neighbor 10.1.1.66.
Example:
Set the route update interval as 20s with neighbor 10.1.1.64.
Switch(config-router)#neighbor 10.1.1.66 allowas-in
