Table 3-7. User-Defined Criteria for IP Inbound Traffic Filters

When specifying the user-defined criterion length, use 8 bits whenever possible.

IP inbound traffic filter criteria with a length of 1 bit work only when aligned on a

byte (word) boundary. Lengths from 2 through 7 bits do not work.

IP Actions

In addition to the Accept, Drop, and Log actions common to all inbound traffic

filters, there are the following IP actions:

• Forward to Next Hop

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 Drop If Next Hop Is Unreachable.

If you specify 255.255.255.255 as the next hop, any frame that matches this

filter will be forwarded normally.

• Drop If Next Hop Is Unreachable

This action is valid only when Forward to Next Hop is in use. It specifies that

if the next-hop address specified is unreachable, the frame is dropped.

• Forward to IP Address

Specifies that any frame that matches the filter will be forwarded to a single

address in a list of specified IP addresses. The destination address of the

original packet changes to the specified IP address.

• Forward to Next Hop Interfaces

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 (unless you also specify Drop If Next Hop Is

Unreachable).
