Assigning Values to the ATM CLP Bit

You can use the forward interface command to specify multiple interfaces and the
forward next-hop command to specify next-hop addresses as possible forwarding
solutions. If you define multiple forwarding solutions for a single CLACL, use the order
keyword to specify the order in which the router chooses the solutions. The router uses
the first reachable solution in the list, starting with the solution with the lowest order
value. The default order value is 100.
NOTE: The forward interface and forward next-hop commands replace
the nest-interface and next-hop commands.
The switch route processor (SRP) module Fast Ethernet port cannot be
the destination of the forward next-hop and forward next-interface
commands.
If you specify a next-hop address as the forwarding solution, you can specify that the
default route is not used as a routing solution for the next-hop address when selecting
a reachable forward rule entry.
IP interfaces referenced with this command can be tracked if they move. Policies
attached to an interface also move if the interface moves. However, statistics are not
maintained across the move.
You can no longer use an interface specifier of tunnel:mpls with the forward interface
command, because that usage requires IP interfaces on top of RSVP-TE tunnels. Such
interfaces are no longer present in the redesigned MPLS architecture. However, you
can configure a static route for an address that is not otherwise used to point to a
tunnel, and then use the forward next-hop command in the policy:
host1(config)#ip route 10.10.10.10/32 tunnel mpls:foo
host1(config)#ip policy-list bar
host1(config-policy-list-classifier-group)#forward next-hop 10.10.10.10

The mark-clp command assigns a value of 0 or 1 to the ATM CLP bit for packets
conforming to the current classifier control list.
Modules on E Series routers support classifying and marking of the ATM CLP bit according
to the following rules:
Modules on E120 and E320 routers support classifying of the ATM CLP bit only for
frame-based interfaces (ATM Adaptation Layer 5 [AAL5] encapsulation), but not for
individual ATM cells (ATM Adaptation Layer 0 [AAL0] encapsulation). In this case, if
the CLP bit in any cell in the frame has a value of 1, the router treats the reassembled
AAL5 frame as if it also had a CLP value of 1.
