Enabling Ipv4 Or Ipv6 On An Access Interface - Cisco ASR 9000 Series Configuration Manual

Enabling IPv4 or IPv6 on an Access Interface

The process of provisioning an IPoE session involves:
• Enabling the processing of IPv4 or IPv6 protocol on an access interface. See
• Creating dynamic template that contains the settings for the IPoE sessions. See
• Creating policy-map to activate dynamic template. See
• Enabling IPoE subscriber creation on access interface by activating service-policy. The service-policy
Note If an access interface in BNG is configured to support only packet (PKT) triggered sessions, or both DHCP
and PKT triggered sessions, then a burst of traffic with unique flows can affect the BNG router in terms
of processing each packet to determine if it is an IPoE (PKT triggered) packet. New subscriber sessions
cannot be established in these scenarios and this can in turn lead to system instability. Therefore, it is
mandatory to configure static lpts policer for unclassified rsp protocol, on each of the line cards (LCs),
such that the traffic rate does not exceed 150 pps per LC. The rate configured is applied at network
processor (NP). Therefore, for an LC with 4 NPs, the rate should be configured as 38 (150/4), to achieve
a traffic rate of 150 pps. For example,
rsp rate 38
Enabling IPv4 or IPv6 on an Access Interface
Perform these tasks to enable IPv4 and IPv6 processing on an access interface. In this example, the IPv4 is
being provisioned on an unnumbered bundle-interface.
