apply clause
IPv6 PBR supports the following types of apply clauses, as shown in Table 9. You can specify multiple
apply clauses for a node, but some of them might not be executed. The apply clauses that determine the
packet forwarding paths are apply access-vpn vpn-instance, apply next-hop, apply output-interface,
apply default-next-hop, and apply default-output-interface in a descending priority order.

apply precedence Sets an IP precedence. This clause is always executed.
apply loadshare { next-hop |
output-interface |
default-next-hop |
default-output-interface }
Enables load sharing
among multiple next
hops, output interfaces,
default next hops, and
default output interfaces.
Multiple next hops, output interfaces, default
next hops, or default output interfaces operate in
either primary/backup or load sharing mode:
• Primary/backup mode—The first configured
next hop or output interface is used. When
the primary next hop or output interface fails,
the first configured backup next hop or output
interface takes over.
• Load sharing mode—Multiple next hops or
output interfaces load share traffic on a per
packet basis in turn according to the
configuration order.
By default, the primary/backup mode applies.
apply access-vpn vpn-instance Sets VPN instances.
If a packet matches a forwarding entry of a
specified VPN instance, it is forwarded in the
VPN instance.
apply next-hop and apply
output-interface
Sets the next hop and sets
the output interface.
Only the apply next-hop clause is executed
when both are configured.
apply default-next-hop and
apply default-output-interface
Sets the default next hop
and sets the default output
interface.
Only the apply default-next-hop clause is
executed when both are configured.
They take effect only when no next hop or output
interface is set or the next hop and output
interface are invalid, and the IPv6 packet does
not match any route in the routing table.
apply continue
Matches packets against
the next node upon
failure on the current
node.
The apply continue clause applies when the
apply access-vpn vpn-instance, apply next-hop,
apply output-interface, apply default-next-hop,
and apply default-output-interface clauses are
not configured or become invalid. For example,
the specified next hop is unreachable, the
specified output interface is down, or the
packets cannot be forwarded in the specified
VPN instance.
