Prerequisites for Configuring ANCP on Cisco ASR 9000 Series Routers

Prerequisites for Configuring ANCP on Cisco ASR 9000 Series
Routers
The following prerequisite is required for configuring ANCP on your network:
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment
is preventing you from using a command, contact your AAA administrator for assistance.

ANCP Adjacencies

The ANCP server accepts TCP connections from access nodes. An ANCP neighbor is any access node
that establishes an adjacency with an ANCP server. ANCP is configured globally, and as long as it is
IP-enabled, there is no restriction on whether ANCP messages are received on the physical or logical
interface.
TCP creates a separate connection socket for each access node. Because access nodes are not identified
explicitly in ANCP messages, the TCP socket serves as the ANCP neighbor identifier for the ANCP
server.

Only Rate Adaptive Mode is supported in Cisco IOS XR Release 3.7 FCI.
VPN routing and forwarding (VRF) awareness is not supported in Cisco IOS XR Release 3.7 FCI.
All IP interfaces receiving ANCP traffic should be in default VRF.
ANCP over IPv6 is not supported for Cisco IOS XR Release 3.7 FCI.
Only VLAN subinterfaces over Ethernet ports (excluding bundles) can be mapped to AN ports using
ANCP.
