General Limitations

RF billing and Lawful Interception do not work together.

DMVPN Limitations

Cisco ASR 1000 devices does not support the ip nhrp server-only command used to configure an interface to operate in Next Hop Resolution Protocol (NHRP) server-only mode.

In a phase 2 deployment, NHRP server-only mode configured on one spoke stops all traffic from the configured spoke to other spokes.

In a phase 3 deployment, NHRP server-only mode configured on one spoke stops the shortcut tunnel from the configured spoke to other spokes and consequently all traffic from the configured spoke to other spokes have to be forwarded by Hub.

We recommend that you do not use the ip nhrp server-only command on Cisco ASR 1000 devices.

MPLS over IPv6 GRE Tunnel is not supported

The mpls ip command can be configured on the IPv6 GRE Tunnel, but it does not take effect.

Limitations and Restrictions in Release 3.6.0

Mediatrace sessions are not established with crypto on WAN link

Mediatrace does not work on ASR 1006 Routers when crypto map is applied directly on the egress interface. This is because mediatrace uses RSVP, which in turn relies on IP Headers that cannot be encrypted in ASR 1006 Routers.

We recommend that you use GRE tunnel interface to apply the crypto map.
