The MAP-E CGN solution without service cards (VSM/ISM) is supported on Cisco IOS XR and Cisco IOS XR 64 bit operating system. |
Restrictions for Configuring MAP-E without Service Card on Cisco IOS XR 32-bit Operating System
-
MAP-E is supported on the 3rd and 4th generation of Cisco ASR 9000 Series Ethernet line cards.
-
MAP-E without service cards can be enabled only in a default VRF.
-
If MAP-E or MAP-T is enabled on an interface, other policy based routing (PBR) features such as CLI PBR, BGP Flow Spec, One Platform Kit (onePK), OpenFlow, ingress ACLs and BNG are not supported. This is because only one PBR policy is allowed on the interface per direction.
-
In a router, only one mode of either inline-service with service card or inline-service without service card is supported.
