Packet Data Network (PDN) Interface Rules

The following engineering rules apply to the interface to the packet data network (PDN):
• Configure the logical interfaces used to facilitate the PDN interface within the egress context.
• The default is to use a single interface within the egress context to facilitate the PDN interface.
• You can configure multiple interfaces in the egress context by using static routes or dynamic routing
• You may also configure next-hop default gateways.

ASR 5000 Packet Processing Card Rules

The following engineering rules apply to the packet processing application cards:
• Configuring a line card to enter the active mode results in the following:
• If you want processing-only application cards, all line card slots directly behind the such cards can be
• If you want standby (redundant) packet processing cards, do not populate line card slots directly behind
• A line card will not handle subscriber traffic unless the packet processing card directly in front of it is

Context Rules

• A maximum of 63 contexts may be configured per chassis.
• Interfaces per Context
If you have enabled the Port Redundancy feature, it is possible for ports on both line cards to be active
while one provides line card redundancy for the other. With the port redundancy feature, each physical
port has a primary MAC address. Each corresponding standby port has a different (alternate) MAC address.
protocols.
• The total number of packet processing cards that will become operationally active is increased by
one.
• In the event of a failure, the line card(s) directly behind the packet processing cards will become
available directly, or to another packet processing cards via the RCC.
empty. Otherwise, disable those line card slots with the shutdown command described in the Command

command as described in the Card Configuration Mode Commands chapter of the Command Line
Interface Reference.
