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:
Switch(config-router)#neighbor 10.1.1.66 allowas-in
35.46 neighbor attribute-unchanged
Command: neighbor {<ip-address>|<TAG>} attribute-unchanged [as-path] [med] [next-hop]
no neighbor {<ip-address>|<TAG>} attribute-unchanged [as-path] [med] [next-hop]
Function: Configure certain attributes which is kept unchanged for transmitting, namely the attribute
transparent transmission. The “no neighbor {<ip-address>|<TAG>} attribute-unchanged [as-path]
[med] [next-hop]” command means the attribute transparent transmission is not performed.
Parameter: <ip-address>: IP address of the neighbor.
<TAG>: Name of the peer group.
Default: No attribute transparent defined.
Command Mode: BGP route mode and address-family mode
Usage Guide: With this configuration specified route attributes will not change when transmitted to the
specified neighbor. The BGP route mode is the IPv4 unicast configuration. No parameter refers to above
three parameter are configured together.
Example:
Switch(config-router)#neighbor 10.1.1.64 attribute-unchanged
35.47 neighbor capability
Command: neighbor {<ip-address>|<TAG>} capability {dynamic | route-refresh}
no neighbor {<ip-address>|<TAG>} capability {dynamic | route-refresh}
Function: Configure dynamic update between neighbors and the route refresh capability negotiation.
The “no neighbor {<ip-address>|<TAG>} capability {dynamic | route-refresh}” command do not
enable the specific capability negotiation.
Parameter: <ip-address>: Neighbor IP address.
<TAG>: Name of peer group.
Default: Not configure the dynamic update capability but the route refresh capability.
Command Mode: BGP route mode and address family mode.
