Route Map Continue - Dell S4048–ON Configuration Manual

BGP soft-reconfiguration clears the policies without resetting the TCP connection.
To reset a BGP connection using BGP soft reconfiguration, use the clear ip bgp command in EXEC Privilege mode at the
system prompt.
When you enable soft-reconfiguration for a neighbor and you execute the clear ip bgp soft in command, the update
database stored in the router is replayed and updates are reevaluated. With this command, the replay and update process is triggered
only if a route-refresh request is not negotiated with the peer. If the request is indeed negotiated (after execution of clear ip
bgp soft in), BGP sends a route-refresh request to the neighbor and receives all of the peer's updates.
To use soft reconfiguration (or soft reset) without preconfiguration, both BGP peers must support the soft route refresh capability,
which is advertised in the open message sent when the peers establish a TCP session.
To determine whether a BGP router supports this capability, use the show ip bgp neighbors command. If a router supports
the route refresh capability, the following message displays: Received route refresh capability from peer.
If you specify a BGP peer group by using the peer-group-name argument, all members of the peer group inherit the
characteristic configured with this command.
• Clear all information or only specific details.
EXEC Privilege mode
clear ip bgp [vrf vrf-name] {* | neighbor-address | AS Numbers | ipv4 | peer-group-name}
[soft [in | out]]
– *: Clears all peers.
– neighbor-address: Clears the neighbor with this IP address.
– AS Numbers: Peers' AS numbers to be cleared.
– ipv4: Clears information for the IPv4 address family.
– peer-group-name: Clears all members of the specified peer group.
• Enable soft-reconfiguration for the BGP neighbor specified.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | peer-group-name} soft-reconfiguration inbound
BGP stores all the updates received by the neighbor but does not reset the peer-session.
Entering this command starts the storage of updates, which is required to do inbound soft reconfiguration. Outbound BGP soft
reconfiguration does not require inbound soft reconfiguration to be enabled.
Example of Soft-Reconfigration of a BGP Neighbor
The example enables inbound soft reconfiguration for the neighbor 10.108.1.1. All updates received from this neighbor are stored
unmodified, regardless of the inbound policy. When inbound soft reconfiguration is done later, the stored information is used to
generate a new set of inbound updates.

Route Map Continue

The BGP route map continue feature, continue [sequence-number], (in ROUTE-MAP mode) allows movement from one
route-map entry to a specific route-map entry (the sequence number).
If you do not specify a sequence number, the continue feature moves to the next sequence number (also known as an "implied
continue"). If a match clause exists, the continue feature executes only after a successful match occurs. If there are no successful
matches, continue is ignored.
