Yes, you use policy routing to implement this, however, all packets
will be process switched (at this time). To implement policy routing,
you do something like the following (mostly from the CCO docs):
access-list 1 permit 174.21.3.0 0.0.0.255
!
interface serial 0
ip policy route-map policy-map
!
route-map policy-map
match ip address 1
set ip next-hop 174.21.3.20
This will route all packets that arrive on Serial0 that have a source
address of 174.21.3.* via the next hop address 174.21.3.20 rather than
what they would have normally used. See
http://www.cisco.com/univercd/cc/td/doc/product/software/ios112/112cg_cr/5rbook/5riprout.htm#xtocid2198498
for more info (but there is a bug in the original example -- you have
to use an access list to specify the 'match ip address' part of the
route map).
