Figure 37-4. Creating a Rule Example
Multiple rules can be applied to a single redirect-list. The rules are applied in ascending order, starting with
the rule that has the lowest sequence number in a redirect-list.
Figure 37-5 displays the correct method for
applying multiple rules to one list.
Figure 37-5. Creating multiple rules for a redirect-list
Note: Starting in release 8.4.1.2, FTOS supports the use of multiple recursive routes with the same
source-address and destination-address combination in a redirect policy on an E-Series ExaScale router.
A recursive route is a route for which the immediate next-hop address is learned dynamically through a
routing protocol and acquired through a route lookup in the routing table.You can configure multiple
recursive routes in a redirect list by entering multiple
seq redirect
statements with the same source and
destination address and specify a different next-hop IP address. In this way, the recursive routes are used
as different forwarding routes for dynamic failover. If the primary path goes down and the recursive route
is removed from the routing table, the
seq redirect
statement is ignored and the next statement in the list
with a different route is used.
