Command Mode:
BGP route mode and address family mode
Usage Guide:
This is an extended BGP capability. With this configuration supported
capabilities by both side will be negotiated in the OPEN messages, and the partner will
respond if this capability is supported by the partner and send NOTIFICATION if not. The
originating side will then send an OPEN excluded the capability to reestablish the
connection. The dynamic capability refers to when the address family negotiation
changes, the connection don’t have to be restarted. Route refresh refers to sending
refresh request when configuring some soft reconfigurable attributes and the partner will
retransmit the existing route to the originating side. With route refresh attribute, the
connection will not have to be restarted but be refreshed with the clear ip bgp * soft in
command.
Example:
Switch(config-router)#neighbor 10.1.1.64 capability dynamic
Switch(config-router)# no neighbor 10.1.1.64 capability route-refresh
13.8.3.44 neighbor capability orf prefix-list
Command: neighbor {<ip-address>|<TAG>} capability orf prefix-list
{<both>|<send>|<receive>}
no neighbor {<ip-address>|<TAG>} capability orf prefix-list
{<both>|<send>|<receive>}
Function:
Configure the out route filter capability negotiation between neighbors. The
“
no neighbor {<ip-address>|<TAG>} capability orf prefix-list
{<both>|<send>|<receive>}
” command set to not perform the negotiation
Parameter: <ip-address>
:Neighbor IP address
<TAG>
: Name of peer group
Default:
ORF capability not configured
Command Mode:
BGP route mode and address-family mode
Usage Guide:
This is an extended BGP capability. With this configuration supported
capabilities by both side will be negotiated in the OPEN messages, and the partner will
respond if this capability is supported by the partner and send NOTIFICATION if not. The
originating side will then send an OPEN excluded the capability to reestablish the
connection. With this capability, the side configured with in prefix-list filter rules will
transmit its own filter rules to the peer, the peer group will apply this rule as its own out
rules, so to avoid sending route which will be denied by the partner.
Example:
Switch(config-router)#neighbor 10.1.1.66 capability orf prefix-list both
13.8.3.45 neighbor collide-established
