Route map continue
The BGP route map continue feature (in ROUTE-MAP mode) allows movement from one route-map
entry to a specific route-map entry (the
sequence number). 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.

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.
• If a set actions operation occurs in the first route map entry and then the same set action occurs with a
different value in a subsequent route map entry, the last set of actions overrides the previous set of
actions with the same
set command.
• If the
set community additive and set as-path prepend commands are configured, the communities
and AS numbers are prepended.
