Table 8-5. Actions and Dependencies for Inbound IP Traffic Filters
Action Command Syntax Description and Dependencies
accept action accept The router processes any packet that matches the
filter criteria and ranges. This value is the default
action.
drop action drop The router does not route any packet that matches
the filter criteria and ranges.
fwd-next-hop fwd-next-hop
<ip_address>
Specifies that any frame that matches the filter will
be forwarded to the next-hop router. You must
specify the IP address of the next-hop router. If the
next-hop router is not reachable, any packets
matching the filter will be forwarded normally unless
you also specify
drp-nh-unreach
.
If you specify 255.255.255.255 as the next hop, any
frame that matches this filter will be forwarded
normally.
drp-nh-unreach action drp-nh-unreach This action is valid only when
fwd-next-hop
is in
use. It specifies that if the configured next-hop
address is unreachable, the frame is dropped.
fwd-next-hop-interfaces fwd-next-hop-interfaces
<ip_address>
Specifies that any frame that matches the filter will
be duplicated and forwarded to a group of next-hop
IP addresses that you specify. If none of the
next-hop interfaces is active, the router forwards
packets that match the filter to the packet
destination address.
fwd-first-up-next-hop action fwd-first-up-next-hop This action is valid only when
fwd-next-hop-interfaces
is in use. It specifies that
any frame that matches the filter will be forwarded to
a specified next-hop router or to a network
connected to the router. If the specified hop is not
reachable, the filter tries all addresses on the
next-hop interfaces list using ARP messages. If
none of the next-hop interfaces is reachable, the
router forwards packets that match the filter to the
packet destination address.
fwd-ip-dest fwd-ip-dest
<ip_address>
Specifies that any frame that matches the filter will
be forwarded to the addresses in a list of specified
IP addresses. The destination address of the
original packet changes to the specified IP address.
