www.dell.com | support.dell.com 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 is displayed: 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. The following example shows how to enable 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 performed later, the stored information is used to generate a new set of inbound updates.

If the sequence number is not specified, 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. continue [sequence-number] Match Clause with a Continue Clause The continue feature can exist without a match clause. Without a match clause, the continue clause executes and jumps to the specified route-map entry. With a match clause and a continue clause, the match clause executes first and the continue clause next in a specified route map entry. The continue clause launches only after a successful match. The behavior is: • A successful match with a continue clause-the route map executes the set clauses and then goes to the specified route map entry upon execution of the continue clause. • If the next route map entry contains a continue clause, the route map executes the continue clause if a successful match occurs. • If the next route map entry does not contain a continue clause, the route map evaluates normally. If a match does not occur, the route map does not continue and falls-through to the next sequence number, if one exists. Set Clause with a Continue Clause If the route-map entry contains sets with the continue clause, then the set actions operation is performed first followed by the continue clause jump to the specified route map entry. 248 | Border Gateway Protocol IPv4 (BGPv4)
